Visiting distant backcountry areas requires accessing hiking trails and then backpacking or horseback riding into remote destinations. Free permits are required for use of the wilderness and can be obtained at trailheads. Group size is restricted in the wilderness, open fires are not permitted in some high-use areas, and visitors are expected to follow Leave No Trace practices. There are abundant trails throughout the forest, with over in the SNRA, in the Fairfield District, and in the Minidoka District. Two National Recreation Trails are found on the forest, the Fishhook Creek Boardwalk at Redfish Lake and the Wood River Nature Trail at the Wood River Campground. All-terrain vehicles are allowed on over of forest roads and some trails, but access may be restricted depending on season and environmental conditions. The Sun Valley area has an extensive network of mountain biking trails. Hunting and fishing are popular recreational activities permitted throughout the forest, provided that proper permits are obtained and the applicable rules and regulations are followed. Hunting and fishing licenses are available from the state of Idaho through the Idaho Department of Fish and Game.
