Due to a lapse in federal funding, this USDA website will not be actively updated. Once funding has been reestablished, online operations will continue. On-going operational updates will be posted here (https://www.fs.fed.us/shutdown) as we are able to provide them.


OHV Trail Riding

Many roads and trails are open to dirt bikes and all-terrain vehicles (ATVs) called off-highway vehicles (OHVs). Roads and trails are designated, by the MVUM, as open or closed to various types of motorized vehicles. Bikes and vehicles must meet all state standards and regulations for noise levels, spark arresters, age of riders, helmet requirements and other
restrictions. Your dirt bike or vehicle must be registered with Colorado State Parks.
