Bicycles are prohibited on backcountry trails and boardwalks. We strongly recommend that safety gear, including helmet and high visibility clothing, be worn by all bicyclists. During April, May, and June, high snowbanks make travel more dangerous. Relatively long distances exist between services and facilities. Motorists frequently do not see bicyclists or fail to give them sufficient space on the road.
Drivers sometimes pass on hill crests, blind curves, or in oncoming traffic.
Vehicles, especially motor homes or those towing trailers, may have wide mirrors posing an additional hazard. For more information about bicycling in Yellowstone, visit our bicycling pages or ask at a visitor center. Following the fires of 1988, thousands of dead trees, known as snags, were left standing in Yellowstone. These snags may fall with very little warning. Be cautious and alert for falling snags along trails and roadways, and in campsites and picnic areas.
