Please do not disturb the black crusts on top of the soil. These 'cryptobiotic crusts' are living plants and protect the desert from erosion. Leave your bike along the road while hiking to viewpoints. Do not ride off-road to avoid sand or mud. Mountain bike riding in a national park requires extra care to protect you and the natural and cultural features.
All routes are on existing unpaved and fourwheel-drive roads.
Riding on foot trails, closed roads or cross-country is prohibited. Pets may not accompany bicycles. Stop at a visitor center, ranger station or park office for current information.
