Fat bikes in Gallatin National Forest




BOZEMAN – Fat bikes may be one of the fastest growing winter recreational trends

in the area, and the Gallatin National Forest’s recreation staff has created a list of

recommended – and legal – areas to ride.

Pedal bikes with large frames and large tires designed for flotation and stability on snow,

fat bikes require snow compaction.

Currently, the Gallatin National Forest’s Travel Management Plan Decision from 2006

prohibits all wheeled vehicles of any type from traveling on National Forest marked or

groomed winter trail systems, including snowmobile and ski trails. This decision pre-
dated the now common occurrence of fat bikes.             

The Forest plans to review the potential for accommodating this growing recreation

activity. However, travel plan amendments take into account many considerations

including safety and potential trail damage; additionally, as a public process, the

amendments involve considerable time and effort, so it is currently unknown what

administrative changes could take place.

Official winter travel routes are shown on the free Gallatin National Forest Over

Snow Vehicle Use Map, available at District offices across the Forest, and online at or on your smart device with the new Avenza PDF map tool. With

Avenza PDF you can download geo-referenced pdf files of Gallatin Visitor Maps, Motor

Vehicle Use Maps, and soon, the Gallatin Over Snow Vehicle Map.

All of these routes may be somewhat compacted by other trail users and snowmobiles, but are
