High Line Canal Trail

Trail now extends to Green Valley Ranch

April, 2025 by rlandis24

Huge improvements to the far northern end of the trail especially north of Colfax Ave. A bike/pedestrian bridge now carries the trail over I-70 to the Green Valley Ranch neighborhood. The city of Aurora has added numerous trail maps. The only thing preventing a 5-star rating are too many road crossings, some of which can be difficult.

Yankee Doodle Trail

Short trail if you live walking distance

March, 2025 by zxr7cncn2c

Nice trail for a lunch time walk. Not worth commuting to. Walked in early spring so not too green yet. I’m sure it gorgeous during summer!

Broomfield Trail

nice, safe, quiet paved trail

January, 2025 by hayes.w.becky

Been walking parts of this trail daily for weeks. It’s a nice, clean, safe and quiet area to walk and ride bikes.

Accordion

Chatfield Dam & Internal Trail

Mostly flat and easy, little traffic

November, 2024 by gcole18594

The only significant climbs are to the top of the dam, whether clockwise past Massey Draw (links to C-470 Trail) or counterclockwise after crossing Plum Creek. The latter climb is gravel as is a 1.2 mile section on top of the dam. A nice, easy, pretty ride.

Boulder Creek Path

This path is littered with homeless people! Their tents, clotheslines, and trash line the river and completely destroy what would be a beautiful view of the river. Worse than the bike paths in downtown Denver!!

Mineral Belt Trail

Amazing Views and Full of History

September, 2024 by mrex2005

This is a great trail for all! It’s paved and there are some side trails. You can take if you want a mountain bike. I would definitely start the trail clockwise. You can park at the Family Dollar. My friends and I rented bikes and packed lunches. Because of so much history along the way it took us 3 1/2 hours to do 12 miles.

Dillon Reservoir Recpath

Don’t be fooled

July, 2024 by vandermolen.m

To go all the way around the lake is very difficult. The entire south side of the lake is very difficult and includes a stretch on a narrow road. The west, north, and east sides were awesome.

Rocky Mountain Greenway Trail

Trail map badly outdated

February, 2024 by kbom

This trail currently extends through the Westminster Hills Open Space and Colorado Hills Open Space almost to Indiana Street.

Big Dry Creek Trail (Westminster)

Great trail for biking

January, 2024 by jennkel5669

Great trail for biking however I wish they would leave the surface alone and stop adding concrete!! Be careful when going into tunnels, these may be flooded and contain debris. You could also take a nasty fall, so please slow down. Lots of wildlife and great for bird watching!

Bear Creek Trail (Denver)

I went hiking here for the first time and it was awesome. Got a real good workout climbing the mountain.

US 36 Bikeway

Great Ride

September, 2023 by oja101

This is an excellent trail to use for your bike rides! Easy to navigate, safe away from all traffic & plenty of rolling hills to enjoy.

Peaks to Plains Trail

Great Trail

August, 2023 by jsafret

We rode this trail as Stage 3 of our Tour de Great Plains and Colorado. Started at the “Big Easy” Trailhead and went west four miles - it’s only open four miles. The pavement is in good shape and about 10 feet wide. The trail is uphill going west and a nice downhill ride back east. There are nice restrooms at the trailhead and plenty of paved parking. This is a beautiful trail and not very crowded. When all segments (65 miles) are completed this will be one of the best trails in the US.
