Bear Creek Trail (Denver)

Interesting Trail

June, 2025 by rpfau147

Rode from MM 0, west to Fox Hollow Golf course. The trail starts in a very urban area, surrounded by many houses and shopping centers. This area the trail is narrow, with some sharp turns. As it goes west it opens up with a wider trail and lots of great scenery. It crosses the Bear Creek trail about 6 times in the first 9 miles. It goes through a park where the trail is surrounded by fields of prairie dogs. The scenery around the golf course is very pretty.

Coal Creek Regional Trail

Great gravel ride!

June, 2025 by nicoleworldwide

We started at the trailhead in Superior and road to the Flagg Creek trailhead. This is a really well maintained, mostly gravel, trail. It winds around a number of neighborhoods and through many open spaces with really interesting views of houses AND the front range mountains. It follows a river crossing it many times. There were only a few road crossings with most of the trail having underpasses with no need to deal with traffic. All in all, a really fun ride!

Vail Pass Recpath

One of the best paved trails in the area!

May, 2025 by troutguy5

This trail has two personalities, from the east (Frisco) and from the west (Vail). It's delightful from either direction but can be crowded with rental e-bikes in the summer.

If you're travelling from the east many people park at exit 201 on I-70 near W. Main Street in Frisco. There's a free parking lot to the SE of that exit. Biking on the Tenmile Recpath takes you along Tenmile Creek, passed several ponds and small lakes to Copper Mountain village. You croos Hwy. 91, then pedal through Copper Mountain village and continue west out of Copper Mountain village near Copper Road and Beeler Place. The trail then follows West Tenmile Creek to the west, parallel to I70. Now the trail is called the Tenmile Canyon Recreation Trail. You'll climb fairly gently but steadily now to the summit of Vail Pass (10,666 ft.). Note that this approach (from the east) is a more gentle elevation gain than the approach from the west, covered below.

If you wish to ride up Vail Pass from the west you can start in Vail Village, near Gore Creek USFS campground or elsewhere in the Eagle Valley to the west. If you start near the Gore Creek USFS campground there is a new, large parking area about 1/4 mile to the SW of the campground; parking is free. Vail Village is about 8200 ft. elevation so the gain, biking on the trail from the west is about 2400 ft with 4 or 5 pretty steep climbs. If you start from at Gore Creek USFS campground parking area you'll ascend past the campground, through an open gate and will parallel I70. This paved trail is the former Hwy. 6 before they built I70. You'll pedal passed a few small ponds and creeks through pines and firs, eventually descending briefly to Polk Creek; this is an excellent place to stop in the shade next to a rushing creek. You'll continue under I70 and ascend over new sections of trail, still heading up to Vail Pass. You'll come to Black Lakes where there is usually a primitive port-a-potty. After passing Black Lakes you have a little more uphill and then you're at Vail Pass. Some people continue to the east and then climb back up and back to Vail; it's your choice.

Weather: in the late spring and summer, even into early fall it's usually warm and dry. Pack plenty of liquids due to aridity and elevation - there are no stores or sources of water on the trail, except perhaps at Copper Mountain. Most days from last spring to early fall there will be thunder clouds building up in the afternoons but it rarely rains. Bring a rain coat just in case.

In mid-summer there are groups of ebikes that people rent in Frisco or Vail (or nearby) and many of these non-locals have very little idea of the rules of multi-use trails so watch out for them! There are occasionally walkers and dog-walkers on the trail but usually nearer Frisco or nearer Vail only.

You may see deer, elk, bear (not likely in mid-day), eagles, ospreys, marmots and other typical local creatures. While blasting downhill one side of the pass or the other be aware that you can easily reach speeds of 30-50 mph so watch out for the rare animal on the path - it IS possible! Have fun!

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.

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!
