An infrequently used trail from US Hwy 6 to the ridge overlooking I-70 just West of the Eisenhower Tunnel. Beginning with an old jeep track, this long neglected trail has numerous deadfall obstacles, stream crossings and challenging route finding (and ascent) as the valley forks near the 1.5 mile mark. Solitude, a cascading stream and expansive views from the ridge.

Good hike once you find the trailhead. Nice river sound the whole way and some nice clearings once you get in 30-40 min.

The trailhead is actually another 1/4 mile east (a little shoulder area big enough for 4 cars at most) of where it takes you from the app. Trailhead is buried in the woods a bit but once you pull in you can see it.

Hard to find the trailhead. Very limited parking. Incredibly steep first 10 minutes but then evens out, although the trail feels overgrown at this point and was difficult to find after about a mile and a half.

I like this trail it's a good quick uphill at the beginning then rolls a little. We went up at the beginning of June and there was still a lot of snow but nothing you can't walk through. The river was running and made for a gorgeous view. We only saw one other couple on the trail and parking is Very limited! The location in the directions is not quite right, just keep going a little up the road, before you hit the run away truck ramp. There is probably parking for 3 or 4 cars.

Gorgeous and quite. Steep incline for the first 10 mins. Runs along side a river. It's not well travelled hence the path can be a bit hard to find after a mile. If you keep going, you will not be disappointed though.

Really nice trail. Stays fairly close to fast running streams which you cross and under the trees making for a cool hike in the summer. Nice variety of terrain. Steep at first but mostly a mild elevation gain.

I like the solitude of this hike. The forest is also very healthy, unusual for this area with the pine beetle infestation throughout summit county. This looks like it may be a good ski tour when the snow flies although parking may be an issue.
