Use extreme caution when riding on park roads; roads are winding and narrow while shoulders are either narrow or nonexistent. Vehicle traffic is heavy most of the time. There are no bicycle paths along roadways.

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. Road elevations range from 5,300 to 8,860 feet (1615 to 2700 meters), and services and facilities are relatively far apart--typically 20 to 30 miles (37 to 56 kilometers).

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, stop at a visitor center.

Bicycling Routes

Several gravel roads are open to BOTH bicycle and automotive traffic. The Old Gardiner Road and Blacktail Plateau Drive allow two-way bike traffic and one-way auto traffic. These roads are best suited for mountain bikes. Please do not block entrance gates when parking at these locations.

Biker / Hiker Campsites

Camping for bicyclists is limited to the developed campgrounds located throughout the park. Campsites are available by reservation and on a first come, first served basis.

The distances separating campgrounds and the fact that the campgrounds typically fill early each day during the peak visitation season will pose logistical problems for the bicycle camper in Yellowstone. A limited number of campsites are reserved for hikers and bicyclists at all campgrounds with the exception of Slough Creek. Camping is not available at Old Faithful. If you are traveling with a group of bicyclists, call Amfac Park and Resorts prior to your arrival to check on group campsite availability; not all campgrounds can accommodate groups. If you have access to a vehicle, use it to find a campsite in your destination campground early each day.

Bicyclists camping without a vehicle can use designated hiker/biker sites for $ 4.00 per individual per night. All other vehicle campsites range from $ 10 to $ 16 per night depending on the campground. Opening and closing dates vary considerably for each campground. Check the Opening & Closing Dates for Facilities page or Camping Page to make sure that a campground is open if you are planning a spring or fall visit to Yellowstone.
