Motorized Travel Regulations

The San Luis Valley Public Lands Center (SLVPLC) manages over 2,500 miles of motorized roads and trails open to the public. 

Authorized Travel All over-land motor vehicles are restricted to designated routes, except where designated as an open travel area (found only on the BLM’s San Luis Resource Area).  If a road or trail does not have a sign designating it open to motorized travel, it is not authorized for motorized use.

OHV Registration Off-highway vehicles (OHV) operating on public lands must have a Colorado OHV registration or a nonresident permit. Registration permits are available from Colorado State Parks. For more information, go to

Game Retrieval Motorized big game retrieval is allowed, but restricted to areas specified on the Rio Grande National Forest Motor Vehicle Use Map. Only all-terrain vehicles (ATVs) may be used to retrieve game between 12:00 p.m. and 5:00 p.m. ATVs must not exceed 50 inches in width and must have large tire surface area and less than 10 lbs of tire pressure. Game retrieval with ATVs must not damage soils and vegetation.

Motorized big game retrieval is NOT allowed on lands managed by the BLM.

Tread Lightly on Public Lands!

Travel responsibly on designated roads and trails or in permitted areas.

Respect the rights of others including private property owners and all recreational trail users, campers and others to allow them to enjoy their recreational activities undisturbed.

Educate yourself by obtaining travel maps and regulations from public agencies, planning for your trip, taking recreation skills classes, and knowing how to use and operate your equipment safely.

Do your part by leaving the area better than you found it, properly disposing of waste, minimizing the use of fire, avoiding the spread of invasive species, restoring degraded areas, and joining a local enthusiast organization.
