“A difficult motorcycle trail that you can technically mountain bike on.”
— Tom Robson
While insanely beautiful, the Nate Creek Trail is not for the faint hearted mountain biker. Its steep ups and downs are indicative of motorcycle use and I wouldn't consider them "mountain bike friendly." However, if you're into hiking your bike uphill and sending it downhill, you should probably try this trail. It has some of the best aspens and views I've ever seen.
From Owl Creek Pass, the trail descends steeply all the way to Nate Creek itself. After crossing Nate Creek, the trail continues north on a very steep ascent. The uphill is mostly rideable and has awesome views of Courthouse Mountain and Chimney Rock. From here, the trail heads uphill on a rideable grade.
Eventually, after rolling past insane amounts of aspen, the trail hits a plateau. From this point, the trail points down on a gnarly and super fun descent. Continue north to then pay penance for the descent and hike your bike uphill. From here, the trail is on and off rideable and may or may not be fun, depending on your inclination.
And finally, you'll reach the intersection with Lou Creek #222. Turn left here to descend an ATV trail, or turn right to hike your bike up to Lou Creek Pass.
