Rules of The Road
The Forest has many unpaved roads of varied terrain that provide miles of fun for the mountain biker. Pick up an Inyo National Forest map, which shows all Forest Service roads and follow these few simple rules.

Stay on open Forest Roads - Closed roads will be posted. Comply with signs and barriers, and leave gates as you found them. Wilderness areas are off-limits to all bicycles and vehicles.

Protect the environment - Minimize erosion by staying on trails and not cutting switchbacks. Meadows, lakeshores, stream banks and vegetation are easily damaged. Avoid wet, muddy areas, as they are more susceptible to erosion. Teach new riders trail etiquette. Don't litter! Pick up more than your share. Lead by example.

Ride safely, Stay in control - You share the forest with other users. Be considerate of hikers and equestrians. Horses can be unpredictable, so yield to them. Wear your helmet and protective gear!

Plan your trip - Take a map, water, first-aid kit, sunscreen and snacks. Be prepared for sudden changes in weather. Don't ride alone and tell someone where you plan to ride; then stick to your plans. Don't take unnecessary chances; help may be miles away in case of an emergency.

About Horses and Mountain Bikes - Over a decade ago, when mountain bikers first encountered horses on the trail, the incompatibility became evident. The swift, quiet approach of a mountain bike upon a horse or pack train can put the animal riders in jeopardy of being thrown. Especially vulnerable are novice animal riders.

Recognizing this, the Forest Service outlawed bikes on trails frequented by pack animals. In the Mammoth area, because of the close proximity to the John Muir Trail, mountain biking was outlawed on many backcountry trails. This policy is enforced. Meanwhile, the Mammoth area has endless miles of forest management roads that are little used and superb for mountain biking.
