Bicycles are allowed on open forest roads, on many forest roads that are gated to prevent motor vehicle travel, and on more than 1,300 miles of summer trails on the Boise National Forest. Many trails are open to multiple non-motorized uses; meaning the trails are shared by hikers, horse riders, and bicyclists. Bicycles must remain on authorized roads and trails; cross-country travel is not permitted. Bicycles are a form of mechanical transport and are not allowed in the nearby Wilderness. Information on allowed trail uses is available on trailhead signs or by contacting the nearest Ranger District office.
