Mountain Biking Twenty Mile Creek Trail

****   Add a review
#86 of 316 mountain bike trails in Idaho
#5,753 in the world

The first 5 miles are mostly smooth rolling singletrack. The last 5 up to Duck
Lake are a good climb with some washed out areas with baby heads and
good technical riding throughout. Turn around at Duck Lake and bomb back
to the trailhead. Most of the technical sections are rideable but will test
your technical riding skills. Much of the area was burned in the mid-90's but
has revegetated well. Good chance at spotting wildlife.

    I have no problem giving this trail a full five stars. It's not for everyone, but I love how it's classic, old school, backcountry riding. The trail is both wicked good fun most of the time and rather frustrating at others, but it's always interesting. There is incredible scenery throughout from rugged mountain ridges to beautiful alpine meadows blanketed in wildflowers. There are rocks, roots, and ruts, all in abundance, especially after the three mile mark, but I love it all.

    As of August 2017, all deadfall was cleared and trail appeared very well maintained, save for a few bad ruts.

    Twentymile Creek Trail was a really fun ride. We did about 8 miles before turning back. Our ride took us to the summit above Duck Lake. On 9/25/2015 the trail was fairly challenging. We only had to lift our bikes over 1 fallen tree but in some places the ruts were really deep. One section was handlebar deep! The lower few miles were in pretty good shape on a flowing trail that meandered through the valley while climbing steadly. After about mile 5 we started to encounter the boulders and rocks. There were a few hike a bike sections. At about mile 6 or so we had to trudge through the overgrown bushes. After the thicket we broke out into a beautiful meadow and continued to the next climb to the summit. This trail has its tough sections where most will walk. It had views that are amazing and can be linked to other trails for either an out and back or a big loop. The Blackwell fire burned through this area in about 1994 and there are still reminders. However the trees are growing back nicely and some areas still have old growth forest. Watch for wildlife at every turn. Animal sightings are common in this area.
    Be safe and have fun!

    too many trees down. Check with forest service before riding.
    First three miles cleared.
    Other good, hard ride.

    The description is good. This isn't a steep trail, but deceptively tough at first. Stay with it, it gets better into several alpine meadows. Its a typical backcountry trail of the area- rocky, rough, technical, but can be fast and flowy as well. If you want a buffed trail stay closer to a major city.
