Trail Access Information

Use your discretion and check with the local land management agency before riding or driving on public lands. Ride and drive at your own risk. YOU ARE RESPONSIBLE!
  • Not all routes are open to all vehicles. Follow the Motor Vehicle Use Maps (MVUMs) and signage for the area and ride only on trails open to and wider than your OHV. Almost all trails in Colorado are subject to seasonal restrictions and closures. Visit the road and trail closure info page for more information. Call the responsible agency before making plans to ride in an area.
  • License Required This symbol indicates areas where most routes are open only to licensed, street-legal vehicles. Please refer to the MVUM for designated ATV and dirt bike routes.
  • Some vehicles such as ATVs and side-by-sides are never street legal in Colorado even if licensed and plated in their home state. These vehicles must have a valid Colorado OHV registration or permit to be used on trails on public lands in Colorado.
