National Monument

Motorized Travel

In order to protect monument resources, motorized and mechanized vehicles must stay on open roads in the monument. Motorized and mechanized vehicles are not allowed on roads closed by the proclamation or roads identified for decommissioning. Vehicles in this classification include Off-Highway Vehicles (OHVs), motorcycles, game carriers, all-terrain vehicles (ATVs), snowmobiles, bicycles, and tractors. These vehicles are restricted to roads that are designated as open to the public for motorized access see the CSNM Motorized Travel Map (PDF).


OHVs are allowed on open roads in the monument, but not on any closed roads as described above. All OHVs used on public lands in Oregon require a State of Oregon ATV Operating Permit.
