Bicyclists willing to brave the often unpredictable elements of spring in Yellowstone National Park are able to travel 49 miles of park roads from the West Entrance at West Yellowstone, Mont., to Mammoth Hot Springs, Wyo., beginning mid-March. There is no bicycle access to Old Faithful or Canyon until the first interior park roads open to public motorized vehicle access in mid-April. (Watch for schedule information from the NPS Website)

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 which may be lined with tall snowbanks. Pullouts may remain snow packed. Extra caution is advised traveling through the five mile long road construction zone north of Norris Junction, which is not paved and may be muddy.

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 will encounter wildlife

Bears, bison, elk, wolves and other wildlife could be encountered at any time. Riders are strongly encouraged to carry bear spray, and should be prepared to turn around and backtrack 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 need to have a plan for self-rescue or repair, and be prepared to be out in severe winter conditions for an extended period of time in the event they experience a mechanical breakdown, injury or other emergency.

The road from the North Entrance at Gardiner, Mont., to Cooke City, Mont., at the park's Northeast Entrance is open all year to cyclists and automobiles, weather permitting.

Cyclists are urged to call 307-344-2109 from 8:00 a.m. to 4:30 p.m. on weekdays for updated road access information, or call 307-344-2113 for 24-hour weather information before committing to any ride in the park. Additional planning information is also available online at http://www.nps.gov/yell/planyourvisit/springbike.htm.
