OFFROAD ATLAS

What is a MVUM? It is a map that shows where you can legally operate a motor vehicle on National Forest land. OFFROAD ATLAS uses your phone’s GPS to show your location on our seamless map. We combine the MVUM with other data such as local roads and our map is easily downloaded for offline use.

You may browse the map while you have wifi or cell service and OFFROAD ATLAS will automatically download any of the areas you view for offline use when you don't have network access. You may also bulk download any of the areas you plan on visiting.

Always have as much information as possible, please consult the published (printable) PDF Motor Vehicle Use Maps available for any individual forests you plan on visiting to get the latest dispersed camping allowances, seasonal closures, and any other relevant information. As always, be careful, many trails and roads are not suitable for passenger car travel. Some are only traversable in the most capable off road vehicles by the most experienced drivers.
Have fun, be safe, and respect the trails.

The OFFROAD ATLAS map service depicts Forest Service roads and trails that are designated for motor vehicle use under the official U.S. Government Code of Federal Regulations for identifying designated roads and trails (36 CFR 212.56). Road and Trail MVUM. Additional roads, such as highways, county roads or public roads, are included for mapping purposes. This map service shows the specific types of motorized vehicles allowed on the designated routes and seasonal designation. Data used in this map service are designed to be consistent with the MVUM (Motor Vehicle Use Map). The road and trail data are compiled from the GIS Data Dictionary data and Infra tabular data that the U.S. Forest Service administrative units have prepared for the creation of their MVUMs. This data is published and refreshed on a unit by unit basis as needed and approved by the individual units in order to stay in sync and consistent with the published MVUMs. Interstate, Highway, Other Major Non USFS Roads, and Historic roads for reference are for mapping purposes only and should not be relied upon for their availability for motorized use.
