Take a compass or GPS, as this is a substantial trail network. There is forested single track, double track and a smattering of access roads. Grunt climbs, fast, twisty downhills, both technical and not, it's all here. Most of the trail is in the trees, with great results when the Aspens turn.
From Nederland, take 119 South for about 1 mile. On the West side, across from Magnolia (County Hwy 132) is the trailhead.
