Explore Littleton. This trail provides a safe way to navigate town with access to the Columbine and Dutch Creek trails. The beautiful landscaping is an added bonus.

Here's a great suburban trail that get's you around town. The Columbine is an important cog in the network of trails in this area.

Cherry Creek Regional Trail

Good trail, inconvenient to access

September, 2017 by alysiacaringi

The trail is great in that it's separated from cars, in some sections it's even separated from walkers and runners, and it makes accessing downtown a breeze. However, there is a major disconnect between this trail and all of the bike friendly streets of downtown. Because the trail follows Speer, arguably the most dangerous and busy street in Denver, it's extremely nerve-wracking trying to get off the trail to access anywhere downtown from most exit points.

Denver's done a decent job of making their streets bike-friendly but the major thing the area lacks is connection of those streets to other streets and trails. Turning left is a nightmare and getting on the Cherry Creek trail is nearly impossible without riding on the sidewalk for a few blocks.

I know what you are thinking. It's a 5 mile trail it's hardly worth the drive. Idaho Springs has made an effort to improve the tourism in their historic town. The trail follows Clear Creek and winds through history. See a narrow gauge steam locomotive, a water wheel, a water fall and the historic district. This ride illustrates the the mineral belt and it's grand history. See how the west was won.

Bumpy workout

September, 2017 by dani.ann.anderson

Good workout but trail pretty bumpy in spots. Take caution as sand and gravel over asphalt periodically. Nice views along Clear Creek.

Fraser River Trail

itty-bitty signage!

August, 2017 by astroman

If you can find the 8" blue signs where the trail starts in Winter park, the first 2 miles are blacktop and really pretty traveling through a forested area with views of the creek and occasional benches to rest. The trail then becomes sidewalk through the busy touristy spots with nice food and beverage options, and LOTS of sidewalk traffic. Again, if you can see the tiny 8" blue sign, you can cross hwy 40 and continue on a blacktop trail for the remaining few miles. There is a great park along the way and this could be a nice stroll for a traveling family.

Good skate

August, 2017 by processing_tl

Good for an inline skate over distance. Some solid downhills and uphills. You will get some serious speed going on the final approach to Boulder. There are a few sharper turns to watch out for in other locations. 95% fresh, immaculate concrete.

Coal Creek Regional Trail

Gradual incline was terrific!

August, 2017 by deb.goss

Had fun on this trail. I started in Erie, although I couldn't locate the trail head by using the directions on here, instead it took to me a residential neighborhood, so I parked there without upsetting homeowners.
Didn't notice the gradual incline, although there were two significant climbs, it wasn't until my return from Superior back to Erie did I notice the decent and FLEW back..... Awesome! Will definitely do this again!

There is a visitor center, the bridge is out just past the center.

High Line Canal Trail (CO)

Be aware of the Santa Fe area of the trail

July, 2017 by jeremy.barton

Approaching Santa Fe is where the trail seems to become really neglected. No crossing assistance whatsoever across Santa Fe is extremely dangerous. Once across Santa Fe heading SW, the trail is extremely rutted and then ends in the middle of nowhere with no signage or any instruction on how to get to the Chatfield section. This section appears to be run/managed by Denver Water but I would highly avoid this area until improvements are made.

Little Dry Creek Trail

Little Dry Creek Trail

July, 2017 by john_man_25

It's an OK trail with a lot of surface street crossings that link cement paths behind backyards in the Northwest section. Heading east from 76th and Sheridan the path dips down into a concrete channel that carries the creek. The feel is industrial, it's an old urban / housing projects area. You climb back out of the channel around Lowell. This area has been closed for construction for about 4 years, but is nearing completion. You can get through it when they are not actively working, otherwise you will have to detour on surface streets. I recommend it for family walks, only OK for cycling.
