OFFROAD ATLAS allows you to safely explore our National Forest land, even offline. The app shows your GPS location on our seamless Motor Vehicle Use Map (MVUM) to help you identify roads, stay on trails, obey use classifications, and navigate alternative routes in and out of the forest. We also offer quick access to the official MVUM PDFs.

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.

Works good WITH cell service

Says you can down load maps for use with out cell service but Map Cache said "download maps will not work till you regain cell service"
If that true what good is it back in the mountains with no cell service

Excellent App! Knew where we were all day long!

We spent 9 hours over two days in a national forest which we’ve never visited before and ALWAYS knew where we were. I could keep track of our progress and made all my turns. We were in a Jeep running roads and trails which were properly labeled to keep us off the atv and utv only trails. I downloaded maps for the forest ahead of time, hooked my iPhone to a Garmin Glo Bluetooth gps, carried the phone in a Ram mount, and ran 12v to both units, not a hiccup all day. Part of the time we had no service too. I was able to investigate the area and trails we wanted ahead of time using the app also. No way I could have the confidence I had using paper maps, this app is worth every penny. Keep up the good work.

Great App for serious off-roading and outstanding customer service.

First off. Those giving bad reviews most likely didn't read what the app is intended for and the areas that is covers. I live in Washington state and all of the national forest are available. Furthermore, I had a few questions and Mike went out of his way to help me with making the most of the app. This app ensures that I tread lightly, plan accordingly and stay on roads that I can legally travel.
