Biking
For information on where bicycles are prohibited year-long, seasonal restrictions, and trail timeshare information, please see the alerts page.
Miles of mountain biking and road cycling exist on the Custer Gallatin National Forest. These opportunities are typically best between June and October, but regardless of season, bikers should always:
- Electric bikes (or E-bikes) are considered motorized vehicles and are ONLY allowed on motorized routes.
- Practice low impact to the soil by limiting riding shortly after the rain, keeping skidding to a minimum, packing out litter and staying on designated trails.
- Control your bicycle, anticipate other trail users including runners, hikers, bicyclists or horses around blind corners and slow down accordingly.
- Always yield the trail. Bicycles are fast and can scare people or livestock. Always make your approach known well in advance; a friendly greeting or bell works well.
- When approaching oncoming traffic on narrow trails, slow down and move off the trail to the downhill side. Give animals extra room and time to adjust to you, all mountain bikers are judged by your actions. Make contacts friendly no matter how brief.
- Leave gates as you found them, respect private property and route closures.
- Know the area, your equipment and plan accordingly, dressing for the weather. Riders should be self-sufficient at all times, wear a helmet and carry necessary supplies for changes in equipment or weather conditions.
- During fall rides, wear a hunter orange mesh vest or bright colors and attach a bear bell to your bike bag to warn hunters of your presence. Do the same for any dog companion joining the ride.
