Roads that Open for Spring Bicycling
- Bicycling, walking, jogging, roller blades, roller skis and similar means of non-motorized public travel may be permitted beginning sometime in late March or early April between the West Entrance and Mammoth Hot Springs prior to these roads opening to motorized public travel.
- Snow removal efforts may also allow for a brief period of bicycle access into the park from the East Entrance to the east end of Sylvan Pass (6 miles from the entrance) and the South Entrance (to West Thumb Jct) depending on road conditions for these early spring activities.
- The road from the North Entrance at Gardiner, Montana, to Cooke City, Montana, at the park's Northeast Entrance, is open all year to cyclists and automobiles, weather permitting.
- The first day of "spring bicycling" is never predetermined and is dependent on road conditions as determined by park staff.
