Other Names

Sawtooth National Forest, Ketchum Ranger District, Greenhorn Creek, Mahoney Butte, Poison Flat, Warfield Creek

Last Known StatusOpen

Located a short distance south of Sun Valley, Idaho, this part of the Sawtooth National Forest features miles of pure single track trails that form multiple loops and wind through grassy meadows, pine and aspen trees.

The trails are mostly smooth with some loose chunk rock and occasional tree roots with light to moderate elevation changes. Dirt bike riders should note that this area is popular with mountain bikes and hikers, so use caution.

The staging area offers plenty of room for parking and while there is no fee charged to park or ride, an Idaho OHV Registration Sticker is required for all dirt bikes. For current conditions contact the Ketchum Ranger District.
