Ride in Yellowstone for free and before the Park is open to public automobiles or buses. It’s a perfect way to spend a day. Bicyclists can travel 49 miles of park roads from the West Entrance at West Yellowstone, Montana, to Mammoth Hot Springs. There is no bicycle access to Old Faithful or Canyon until the first interior park roads open to public motorized vehicle access on Friday, April 21. A bicycle trip into Yellowstone this time of year is not to be undertaken lightly. The quickly changing weather can be challenging. Snow and ice may still cover sections of road. Tall snow banks may line roads and pullouts be may be snow packed. Bicyclists are required to ride single file and follow all other rules of the road. Cyclists should expect to encounter and yield to snowplows or other motorized vehicles operated by park employees or construction workers traveling in conjunction with park operations. Bicyclists should be prepared to encounter bears, bison, elk, wolves, and other wildlife at any time. Riders are strongly encouraged to carry bear spray, be prepared to turn around when encountering wildlife on the road, and must stay out of closed areas. No services are available along these sections of road. Cell phone coverage throughout the park is sparse and unreliable for communicating emergencies. Riders should plan for self-rescue or repair, and be prepared for severe winter conditions for an extended period of time in the event they experience a mechanical breakdown, injury, or other emergency. More information can be found on the park’s website at Spring Bicycling. Cyclists can call 307-344-2109 from 8:00 a.m. to 4:30 p.m. on weekdays for updated road access information.
