Small network of singletrack trails. Two loops (maybe more?): Camp Trail and Corner Mountain Trail. Sometimes rocky, with some downed trees and gullies to tackle. Pine forest with aspen groves. Less climbing than Little Laramie Trails nearby. Trails well marked. $5 day use fee, or buy season pass at USFS Visitor center on US 130 near trailhead.
Take US 130 west from Laramie about 30 miles. Continue west past Centennial, WY a few miles. The trailhead is on the south side of the US 130, after Libby Creek and before the N. Fk. Little Laramie River bridge.
