Sawtooth National Forest/Baumgartner Trail/South Hills
You’ll find 440 miles of inventoried trails in the district, many of which top out in mountain lakes or bowl-shaped basins.
The Baumgartner area, situated alongside the South Fork Boise River, offers hundreds of miles of trails for motorcycles and ATV and UTV riding, so you can explore for miles without ever retracing the same ground. (UTVs are permitted in some areas, but many of the tracks have a 48″ wide limit or less.) Iron Mountain Lookout offers a steep ascent that can prove challenging for even the most experienced riders.
The South Hills area (officially the Cassia Division) is known to local ATV riders to offer more than 50 miles of trails on both sides of Rock Creek Road, in the shadow of Pike Mountain. Trails consist of hardpack, sand and rocks, along with some mud bogs and a few water crossings. Recreation areas here where you’ll find great riding include Diamondfield Jack Campground, Magic Mountain Ski Resort and Porcupine Springs Campground.
