This loop is accessible from multiple major points: Stapleton, Lowry, central Denver, the Highline Canal, and the Cherry Creek Trail. It also gives riders a great opportunity to ride through parts of Aurora that see little cycle traffic and thus to get some relief from the crowding on the Cherry Creek and Platte River Trails. The maps shows the multiple entry points possible to the loop, including brand new connections from the Stapleton area between 26th and 25th avenues.Navigationally, there are a few tricky spots, especially as you make your way from Iliff south to the Cherry Creek Trail. These maps and photos will make it easier.
If you are coming or going from the Stapleton area, the route between Montview Blvd/25th Avenue and Sable Blvd at 13th Ave is pretty straightforward. The Denver portion of Montview has a dedicated bike lane that disappears at the Aurora/Denver border, at Yosemite St. I recommend using 25th Ave to ride between Clinton St and Peoria St. The traffic intensity is lower and the views are better. Once you’ve gotten to Fitzsimmons Parkway near the Anschutz Medical Center, cross over Sand Creek on a bridge just east of the golf course to reach 29th Ave and Sable Blvd. A small amount of dirt (crusher fines) is involved. And if you are coming from Stapleton and are looking for a slightly shorter approach to and from the loop, use Moline St between 25th Ave and 2nd Ave with a jog west to Lima St to reach 1st Ave and the loop itself.
If you riding from Denver, 6th Ave is a great, if surprising choice, between Colorado Blvd and Uinta St. There’s a narrow parking lane in this stretch, but I suspect it is so narrow that most people are reluctant to park in it and it becomes a good de facto bike lane instead. Once you’ve worked your way through the Lowry neighborhood leave Lowry Parkway at Yosemite Way and work you way east and south to Moline and then Lima St. From there it is a fine ride on dedicated bike lanes south to the reservoir, interrupted only by traffic lights at the major intersections. Once across Iliff Ave, work east and south on Wesley and Nome St to reach Yale Ave and then Peoria St. The stretch between Peoria and Parker Rd is fast and reasonably safe, even at rush hour. There are three lanes and drivers are mostly friendly. Watch out for the multiple deep manhole covers in the right lane. At Parker Rd, take the western turn lane to access a wide sidewalk and underpass that avoids the off ramp from I-225. Then ride east to the RTD station (Nine Mile) and south through it to join the Cherry Creek Trail.
If you are northbound on Peoria from Parker or even if you find the traffic intensity not to your liking, there’s a sweet neighborhood route that takes you across Yale from Nome or Oakland streets, through a quiet residential area, and then out to Cornell St on a narrow path through the Cherokee Apartment complex. The path runs parallel to a shallow drainage ditch and shows up as public bicycle route on Arapahoe County GIS maps. I found it odd the first few times I rode the path but nobody I’ve encountered has ever said anything at all.Ride the Cherry Creek Trail into the state park, then follow the trail easterly (towards the east park entrance) until you come across the exit to the Spillway Trail, on your left. Leave the park. Cross on-and off-ramps to Parker Rd to reach the Spillway Trail proper. Follow it northeast, crossing Chambers Rd and Iliff Ave in the process and passing through a nice succession of local parks. North of Iliff you’ve entered the Horseshoe Natural Area, a place where multiple trails converge without great signage. Although it looks as if you should maintain a northerly direction after entering the natural area, it is more convenient to turn right after approximately .3 miles and work your way around the north and west sides of the baseball fields. Hug the creek on your left to reach the Tollgate Creek Trail. Anything else will take you further east (Power Line Trail) or south again (Tollgate Creek Trail and West Tollgate Creek Trail). Ride north.After crossing or passing under the major east-west roads of the metro area, the trail sneaks off to the right just before Alameda Ave so that you do not have to cross Alameda at grade. The by-pass is narrow, looks almost like a concrete foot path and is easy to miss. As you emerge on the north side of Alameda, turn right to ride the Highline Canal Trail under Chambers Rd, pass the Aurora City Government Center, and continue on to Sable Blvd. Ride north on Sable in the right lane, jog right, then left on Sable at 6th Ave and continue north to 13th Ave or 29th Ave, depending on your route selection. 14th Ave dead ends at a scraggly open area which could be a park someday. A path takes you under I-225 and across the creek on a sketchy metal bridge. It is narrow, but safe.
Ride east on 13th Ave to Del Mar Parkway. A quick left and a right on Geneva Street bring you to 11th Ave. Ride it west to Uinta St, go south and you’ve completed the loop.
If you ride this loop in the opposite direction, one of the tricky spots is the left turn from Sable Blvd southbound to the Highline Canal. There’s a median through which you pass–but the pass-through is at an angle, is narrow, and is raised. Patience works well here, first to let southbound traffic behind you pass and clear and second to let northbound traffic go by, as well. The only other tricky spot is northbound on Peoria St between Parker Road and Yale Ave. As discussed above, traffic intensity on the weekends is not terrible on Peoria northbound, but if that’s not a happy option, use the neighborhood by-pass through the Cherokee Apartment complex.
In the dark days of the year, when the days are short and there’s not enough light to ride before or after work, I frequently ride at mid-day, over lunch for an hour or so. The rides are not very complicated. They take about an hour to complete. And they are geographically diverse so that I don’t get that stuck in a rut feeling where I’m always going to Washington Park or out to the Cherry Creek Reservoir and back, like some mindless lemming with no itch for new places and sights. They are also useful as easy recovery rides. These short loops include the Stock Show Loop, which takes you mostly north and slightly east of downtown, the Eisenhower Park Loop (south and east) and the Bible Park Loop (east and south). Bryant Street takes you south and west.
Most of what you need to know is on the maps themselves. But a few words are probably helpful.
Bryant Street Loop features my favorite short hill in metro Denver, between Dartmouth and Bates, two blocks of sheer steepness that flirt with the mid-teens in grade. Were the hill longer, the neighborhood would be overrun with Lycra. There are a few other, smaller hills, too, on Zuni Street as well. If they catch your attention, check out the Hill Junky Circuit. I’ve suggested riding this loop clockwise for two reasons. It makes the Mississippi stretch more manageable (a longish downhill run instead of a slow slog uphill) and it makes the navigation to Washington St (the one-way southbound that parallels Emerson St) a lot easier. But if you’re persistent enough, you’ll figure out how to make it work. The sketchiest part of the ride is between Platte River Dr and Broadway on Mississippi. The road is rough. There’s a gloomy underpass. And sometimes the traffic is intense. Don’t let these factors throw you off. Either time your entrance into the tunnel so the bulk of the traffic has passed, or find and use a sidewalk on the north side of Mississippi for a relatively safe passage through. Don’t miss the sheer bliss of the bike lane northbound on Emerson St. It is a great alternative to Washington Park.
If you are signed up for the Triple Bypass and think you need one more hard training ride to be completely ready, here’s the ticket. The Silver Road Half Century starts in Georgetown, rides up and over Guanella Pass, and returns to Georgetown. 48 miles, more or less, and more than 6,000 vertical feet up to a high point of 11,669. Twice. The combination of serious climbing and serious altitude should be irresistible. The SRHC will be held on June 30, 2013, in conjunction with the Guanella Pass Hill Climb, an organized USAC sanctioned race. So if you are into hard rides but not racing, the SRHC is the one for you. The ride is limited to the first 250 riders who sign up and is fully supported with aid stations, first aid support, and Al’s Pit BBQ on the U.S. 285 side of the ride. (Al’s, by the way, is worth a trip in its own right, but probably not when you are halfway through this ride, with 3,000+ feet of climbing still to go.)
You’ll have to get up early–the ride starts at 7:00 a.m. in waves of 50 a few minutes apart to avoid congestion with the racers, the first group of which head out at 8:45. The ride benefits Colorado Lungs4Life, The Davis Phinney Foundation for Parkinson’s Disease, Georgetown Trust for Conservation and Preservation, and the Bicycle Racing Association of Colorado Junior Development Program. These are serious charities and the ride expects you to raise serious money: registration costs $55 and you must raise $150 or more to enter the ride. At the $150 level you get a beautiful hat and t-shirt. Above that level there are these jerseys and vests from Pactimo.
The Lakewood Gulch Trail system received a much-needed and complete renovation on account of RTD’s development of the West Line of FasTracks. The line runs between Denver’s Union Station and Jefferson County’s Government Center in Golden. The cycling improvements include both dedicated trails and low traffic streets, primarily along 13th Ave north and south of the rail corridor. The only difficulties that you’ll encounter are when you cross the two sets of tracks (one east, one west), something you’ll do at least three times if ride the full length of the trail (which ends just past Kipling St). Sadly, there’s no access through the Federal Center and beyond. There is a crossing within the Sheridan Street Station, a crossing at Estes St, and a crossing at Garrison St. All require caution on account of the tracks themselves (cross them perpendicularly!) but are protected by barriers to prevent the unwary cyclist or car from slipping in front of an oncoming train. The Sheridan Station is different–it is an unprotected crossing with a set of switchbacks on the north side. The trail is otherwise straightforward with a slight hiccup after Sheridan that requires a two-block detour to the north.
You can easily ride out and back to Kipling St on the trail and 13th Ave, but Garrison St is a good place from which to begin a longer adventure. Garrison links to the north with both 20th and 26th avenues and to the south with the Bear Creek Trail system. More exciting is the new link out to the Red Rocks, Morrison and points beyond, shown in this map. At Garrison, ride south 12 blocks to Alameda Ave. A broad sidewalk on the south side of Alameda connects Garrison to Kipling. Cross Kipling and stay on the south side of Alameda all the way to Bear Creek Blvd. A mix of trail, frontage road and sidewalk takes you to the point where Alameda bends sharply west and drops down near Green Mountain to join the C-470 Trail and Rooney Rd with links north (Golden, US 40, and Golden), south (Morrison, Bear Creek Lake Park, C-470 Trail) and west (the Hogback and Red Rocks Park). The only caution required is along the frontage road sections as you cross the many streets large and small between Kipling and Bear Creek Blvd. You must watch for traffic turning from the north and south of these streets as well as traffic coming from the east and west on Alameda. That means looking left, right, in front of, and behind you. Beyond that, this is just great metro riding with many links to the foothills and beyond.
Tollgate Creek is the major tributary of Sand Creek and drains (or at least used to before Cherry Creek and Aurora Reservoirs were built) the eastern plains between the two reservoirs. As close as it is to most urban cyclists, it sees little bicycle traffic. If the lack of use reflects uncertainty about how to link it up to make a loop, this map will help. The trail proper runs from the historic Delaney Farm in Aurora south to Iliff Ave. A branch of the trail heads southeast at Horseshoe Park and winds down to Quincy Ave with an optional tour on the Highline Canal further south to the Aurora Reservoir.
The route shown here is Denver-centric and takes advantage of Montview Blvd and the little-used but very quiet 25th Ave to reach Fitzsimmons Parkway. A bridge across Sand Creek spills you out on 30th Ave and then to Sable Blvd. Sable Blvd will carry you south to the junction with the Highline Canal (apprximately 2nd Ave). Sable Blvd between 30th Ave and the Highline Canal offers very good on-street cycling. There’s a jog at 6th Ave and a left turn back onto Sable, but it’s entirely manageable if you make the turn from the right (north) turn-lane of two. The intersection with, and turn onto, the Highline Canal Trail is not so friendly. First, a very narrow bike lane carries you up a hill to where the trail crosses Sable. Second, the concrete median has a diagonal cut in it for cyclists but it’s a hump, it’s narrow, and not easily accessible if there’s traffic behind you. Third, there’s no turn lane. So if you’re feeling pinched by traffic your first time through, stop to the right, in the bike lane. Wait for traffic to clear behind you and roll into the median slowly while you gauge the flow of northbound traffic. Once across you’re on a great stretch of the Highline Trail. It winds along the canal, passes by the Aurora city center and joins the Tollgate Trail at Alameda Ave. Exit right and up then immediately down to access Tollgate Trail. I’m always a little confused here because you leave a smooth gray concrete trail and connect to Tollgate on a rough, dusty looking stretch of pavement that hardly looks like a trail at all. Go south from here to smooth sailing on Tollgate Trail. At Mississippi Ave you surface, go east, then drop down again to creek level. At Mexico and Iliff Ave negotiate at-grade crossings with traffic lights. You’ll approach a triple trail junction just before Iliff. There’s little signage but the baseball field at Horseshoe Park will be your sign to turn west to cross the creek and then head south.
Follow the trail south through the sprawling Wheel and Olympic Parks to reach the Cherry Creek Reservoir Spillway Trail. Fine riding continues. Cross Chambers Rd at the light. Ride south. Just before reaching the reservoir be wary of high speed traffic at the Parker Rd and Hampden Ave interchange. There are traffic lights at both crossings and they are essential at rush hour. Enter Cherry Creek State Park and make choices about returning to where you start. Turn right for the direct route (along the Cherry Creek Trail) or left to circle the park or explore points beyond.
If you ride this in reverse order, the only caution is the turn from Fitzsimmons Parkway onto Peoria St to reach 25th Ave. It is uphill, there are only two lanes, and there can be high traffic intensity during rush hours. It is a short tenth of a mile but if you are feeling beleaguered, there’s a narrow sidewalk you can use.

Fires in Fort Collins have played havoc with Bicycling Racing Association of Colorado’s ability to stage a championship race for masters and juniors this year. The Fort Collins Cycling Festival was slotted to host the races this year but the High Park Fire, which destroyed 90,000 acres west of Fort Collins, made that impossible. With little time to organize, BRAC, Lima Beans Cycling, and Team Rocky Mountain Health Plans pulled together both a masters and a juniors state championship. The new location is in Keenesburg, Colorado, just 50 minutes from Denver on I-76. I haven’t ridden the course yet but hope to this weekend. The race will also be a fundraiser to help those affected by the High Park and Waldo Canyon fires, a chance as BRAC puts it, “for the cycling community to come together and show Colorado that we care.” Rocky Mountain Health Plans has kicked off the fundraising with a $500 donation. The racing begins at 8:30 a.m., August 19 with the juniors headed out on a 19K course, followed in short order by everyone else. You can find the race flyer here and sign up here.
Metro Denver has a goodly number of fine roads that run east and west (think Dartmouth Ave, Montview Blvd, 26th Ave, and 46th Ave just to name a few) but not nearly enough that run north and south. I’m not sure why this is so and I speculate about it endlessly as I flog my way north and south, interrupted by stoplights, stop signs, hospitals, and golf courses. I’m being slightly hyperbolic. Tennyson St, Zuni St, and Lowell Blvd are good in stretches. Holly St is OK. Sable Blvd in Aurora works OK if traffic intensity is light. Further west Rooney Rd and Johnson Rd connect to create a really good stretch of climbing heaven. That dearth of good north south routes was the genesis of the Metro Loop de Loops ride. Garrison St on the west runs mostly uninterrupted from US 285 (Hampden Ave) to 26th Ave, much of it with a dedicated bike lane. It totals about 7 miles if you include the stretch of Estes St between Morrison Rd and US 285. The east side of this loop is a little more cobbled together: the “standard” route through Washington Park to Dartmouth Ave and then to Clarkson St. The beauties of this loop are many. You’ll use portions of five of the metro area trail systems (Cherry Creek, Clear Creek, South Platte River, Big Dry Creek, and Bear Creek). You’ll pass through or near multiple parks and golf courses. You’ll ride by at least five big lakes and reservoirs. Add in two KOM segments at Berry Ave and Tennyson St and you’ve got all the makings of a classic metro loop.
The route finding is pretty straightforward with maybe three tricky spots at Bowles Ave, in Wheatridge, and then in sneaking across 38th Ave to return to Confluence Park. These are all places you are likely to return to at some point in your cycling life so you may as well figure them out now. I’m including a couple of detailed maps to help you if this is your first time. If you’ve ridden some of CBM’s other routes, you’ll recognize this as a conglomerate of several other routes. The description below is for a clockwise ride, which I like for the short climbing segments on Berry Ave and Tennyson St. Switch them around in your head if you want to go the other way.
Start in Confluence Park. Head upstream along the Cherry Creek Trail to exit at Downing and make your way through Washington Park. Exit the park at Franklin St and work your way south and slightly west to Clarkson St. Ride Clarkson all the way south to Sunset Lane (3 miles) and watch for the Big Dry Creek signs. Jog over to Washington St and Powers Ave and you’ll soon be flying down the Big Dry Creek Trail to join the S Platte Trail, about 2.5 miles. Go south about 1.5 miles and exit at a roundabout immediately before Bowles Ave. Look for the big white tennis bubble as your landmark. Skirt the bubble to the south to gain the sidewalk of Bowles. Cross Federal Blvd (carefully!) on the sidewalk and ride west (still on the Bowles Ave sidewalk) to a narrow fence opening onto Julian St. Home free. Ride north on Julian St to Berry Ave. Go west. The first KOM segment begins at Lowell Blvd. and climbs 5-6 blocks steeply.
Ride through the Bow Mar area skirting Bowles and Marston Reservoirs on roads of your choice (there are several options, all good) or just stay on Bow Mar Drive to connect to Sheridan Blvd. Take note of but ignore the signs at the entrance to Bow Mar that say there’s no exit. They are liars. Ride out of Bow Mar on Sheridan to Quincy and turn east. Both Sheridan and Quincy are fine for riding a bike. At the Lowell Blvd traffic light go south (left) through a narrow opening in the chain link fence. If it is your first time, use caution: cars are not really expecting you to make a left turn here. Ride south on Lowell Blvd past Fort Logan, CMHI, and Mullen School. Just past Mullen, look for the Bear Creek Trail at grade on your left. Get on it and go. This used to be a nasty section of trail but has been considerably improved in the last year (2011) and now makes for some OK riding. (If you want more climbing, stay on Lowell north to Dartmouth Ave and ride it west until it joins the Bear Creek Trail at Webster St.) Ride the trail west to Estes Park, about 3.8 miles. Exit the trail to the north, across Bear Creek on a bridge. There’s no signage, so if it is your first time, watch your odometer: about one mile from Webster St where the trail crosses Bear Creek. Estes Park makes a fine snack/refuel/pit stop. There are restrooms located in the middle of the parking lot.
Ride north on Estes St and Garrison St. As you cross Morrison Rd look for the sidewalk+path on your right. Take it and ride up the hill to Baltic Ave. I don’t usually strongly recommend a sidewalk, but I make an exception here. The short stretch between Morrison Rd and Baltic is scary-narrow with little room for recovery from another’s inattention. Southbound riders have a good bike lane. Ride north until you reach 26th Ave. The bike lane disappears in a couple of places but heads up riding is all it takes to stay safe along this fine stretch of urban riding. Between Colfax Ave and 20th Ave follow the path of least resistance through a series of Scottish themed streets. At 26th Ave ride west. Cross Kipling St. Go north on Paramount, Twilight and Hillside to reach 32nd Ave. Alternatively, you can easily ride one of the many trails through Crown Hill Park to reach 32nd Ave. At 32nd Ave access Holland St, 37th Ave, and Independence St to make your way north to the Clear Creek Trail.
Ride northeast on Clear Creek Trail. This is probably the nicest stretch of Trail, good shade cover from the many large cottonwood trees, proximity to the creek itself, and little of the urban industrial blight that plagues the stretch between Tennyson St and and the confluence with the S. Platte River. It is about 4.3 miles to the at grade intersection with Tennyson St. with all of it on the trail except for a two block stretch between 51st and 52nd Aves at Gray St. Follow the signs northerly (or southerly if you’re coming the other direction) and you’ll be fine.
Ride south on Tennyson St, jogging west and south at 52nd Ave to gain the high ground next to Willis Case Golf Course. This is the other short KOM segment. Ride south to 46th Ave. Turn east and ride to Lipan St. Go south to 37th Ave, east to Inca St and south to a short spur of trail that disappears under the bulk of the I-25 overpass looming in front of you. Follow the spur to Rockmont Dr and Platte St (the one turns into the other at Cuernavaca Park). Platte Street returns you to 15th St and Confluence Park. If you’re smart, though, you’ll stop at the Denver Beer Company for a pint to celebrate.
Guanella Pass runs from I-70 at Georgetown to US 285 just west of Bailey. For the full version of the pass, check out this post. The pass was paved in 2012 (but not quite all the way to US 285), thus adding yet another classic climb to a state that already has an embarrassment of riches in long, steep climbs. Start in Georgetown or better yet start in Idaho Springs. If you start in Idaho Springs , it is 24 miles one way with 4,300 feet of climbing. All but 1,000 feet happen in the 10.5 miles from Georgetown. There are steep sections at the beginning and end that flirt with double digits and a few small breaks as you work your way past a series of artificial reservoirs used to generate electricity through a pump-back process. By the time you reach the top (11,670 feet), you’re above treeline and the views of Mt Evans and Bierstadt are extraordinary. The climb will certainly become one of the classic Colorado climbs, as hard or harder than Squaw Pass from Idaho Springs, Vail Pass (from the west), Lefthand Canyon, and Golden Gate Canyon. As I understand the Rocky Mountain Cycling Club’s formula for difficulty, Guanella Pass rates as the fifth or sixth hardest climb in the state, right up there with Trail Ridge from the east and Molas Pass from the south.
There’s good parking in Idaho Springs at the lot behind Beau Jo’s and also next to the EMS station on Chicago Creek Rd, with free Forest Service bathrooms at the NFS Ranger Station. Don’t actually park in the Forest Service lot–it is for short term information and bathrooms only. The ride up to Georgetown along the frontage road you probably know from shortcuts in the winter when I-70 is backed up. When there’s no traffic, the ride is a sweet one, next to Clear Creek and with little traffic. Leave Idaho Springs on Colorado Blvd. Cross immediately to the south side as you reach the western outskirts of Idaho Springs. Ride upstream. Near Dumont cross back to the north side. This will be obvious because you just need to follow the paved road. Ride through Downieville (there’s a Starbucks there and a convenience store) and cross under I-70. Ride 1/2 mile to a fork. Go left to cross Clear Creek one more time and follow what’s known as Alvaredo Rd and CR 306 all the way into Georgetown. The road is in good shape.
Ride into Georgetown on what is now Argentine St. At the Y with Loop Rd, bear left on Brownell St. Turn left on 6th St, right on Rose St and you’ll be climbing for real in a few short blocks. The climb begins steeply with switchbacks, levels out for a few short moments near the hydropower reservoirs, and gets steep again at the top. You can read a detailed description in Russell Harding’s Blog, The Road to Cat 1, if you like to know in advance how much you are going to suffer. I know I adapt badly to altitude so reading a detailed description does not help me much. Anytime above 9,000 feet hurts. But here’s the profile if you’re a visual learner.
At the top, there’s a large lot to the west with a Forest Service outhouse if you need it. The views are great and the descent is fast and smooth, a treat if you’ve ever suffered coming down from Mount Evans, which you can see from the top to the east.
The Sunnyside neighborhood is one of the four neighborhoods that collectively make up the area that most refer to generically as “The Highlands.” The others are Highland, West Highland, and Berkeley. Bounded by Federal Blvd, 38th Ave, I-25 and I-70, Sunnyside has yet to be overrun by hipsters, espresso shops, and micro-breweries. It took me a while to figure out how to get easily to 46th Ave, which ranks in my personal top ten as one of the best east-west streets in Denver, right up there with Dartmouth Ave, Montview Blvd, and 26th Ave. (Aside: have you ever noticed that there are far more great east-west streets in metro Denver than north-south?) Then I discovered a short piece of trail near an abandoned factory out past Cuernavaca Park that provided the missing link and avoided a scary underpass on 38th Ave and multiple twists and turns along Central Ave. The Sunnyside Loop takes in a good chunk of 46th Ave, the Cottonwoods section of Clear Creek Trail, a short stretch of residential climbing hear the Rolling Rock Golf Course, and returns along 20th Ave. You can ride it in either direction. I like going west on 26th Ave and east on 20th Ave, but everyone has a different idea on which is better.The description below starts at Confluence Park and goes counter-clockwise.
Start at Confluence Park. Get out to Platte St by leaving the Platte Trail at 15th, 16th, or 19th Streets. Ride north on Platte St to where it dead ends in a circle at Cuernavaca Park. This last stretch of road is called Rockmont Drive and honors the now defunct Rockmont Envelope Company that still graces the site, awaiting the right developer and a recovering economy for further direction. Ride north on the trail spur to connect to 37th Ave and Inca St. Some good graffiti and an interesting view of Denver will greet you.
Snake your way along Inca St and 37th ave to reach Lipan St and cross 38th Ave to reach 46th Ave. Ride west on 46th Ave to Tennyson St then go north (right) past Willis Case Golf Course to 52nd Ave, the northern boundary of Denver proper. Jog right and left to stay on Tennyson and descend a fast hill to intersect the Clear Creek Trail. It is not well marked but look for the pedestrian crossing sign and stop if you see the water in the creek.
East of here Clear Creek Trail is pretty industrial, but the stretch between Tennyson and McIntyre streets is more natural with good shade on hot days and interesting parks and bridges to hold your interest. Route finding is generally easy–look for the Clear Creek Trail signs and follow them. Sometimes around the many parks along the way there are two possible routes–just follow the trail of least resistance and you’ll be fine. if there’s been a lot of rain, avoid the underpasses along the major roads. Don’t be stupid or careless. If you are caught in a downpour and Clear Creek floods, move to higher ground–don’t seek shelter in one of the underpasses. The trail is interrupted twice, once at 52nd Ave and once again near Kipling St and the Wheatridge Recreation Center. The first interruption takes you briefly along quiet city streets.
The second detours under Kipling and through the Rec Center parking lot. If the Kipling underpass is flooded (it collects water easily) cross (without a light) at 41st Ave or at Kline St (with a light–just south of the Rec Center).
Watch for two sharp sequential humps along the trail, ridges really, that could throw the unwary cyclist. You can also shorten this loop by exiting the trail just before Kipling St at Independence St and riding south to connect to 32nd Ave. Surprisingly, all you need to do is follow the signs.
Exit the trail at McIntyre St by leaving the trail before Mcintyre and ride west on the Frontage Rd to make the turn on McIntyre. How will you know? Look for this building on your left. And if you pass under McIntyre by mistake, don’t worry. Just reverse course on the ramp and enter McIntyre from the west side–it is just an awkward maneuver and the exit from the Frontage Rd makes it simple and seamless.
Ride south on McIntyre to 32nd Ave. Go east (left) a short distance to Kendrick St (look for the sign for the Rolling Hills Golf Course) and escape 32nd Ave by riding south (right) on Kendrick to Fooothills Rd. Turn east (left) on Foothills. Climb through a small residential area and work your way east to Eldridge St. Go south (right) to join 20th Ave.
2oth Avenue is a great route east back into Denver. Watch out for a narrow area through Lena Gulch (where the Maple Grove Reservoir starts). Otherwise, there is a striped bike lane for most of the return. Just before Sheridan Blvd, detour around Sloan’s Lake at Depew St. Ride south t0 17th Ave, then east again to Sports Authority Mile High Stadium. You’re almost home. Circle the sports complex to the north or south and rejoin the Platte Trail just east of the Stadium. Ride the trail north (left) back to Confluence Park.
