Backcountry Discovery Trail The view from the top of Little Volcano, elevation 5801 feet. The Plumas Backcountry Discovery Trail (BDT) invites exploration of the remote areas of the Plumas National Forest. You can expect rough road conditions on gravel and dirt roads and a slow pace of travel, maybe only 30-50 miles a day. Be prepared for downed trees or rocks on the road, rough and rocky surfaces, and brush encroaching on the road-way. Much of the route is under snow in the winter and early spring. There are no restaurants, grocery stores, or gas stations along the main route and cell phone coverage is intermittent. Then on-paved roads are currently maintained for travel by sport utility vehicles (SUVs) and high-clearance vehicles. This guide book describes the various routes and makes some recommendations on what types of vehicles canuse them. Alternate routes, which are best traveled in a 4-wheel-drive vehicle, are high lighted as well.
