Each year an increasing number of bicyclists visit Glacier. Most seek to ride portions of the engineering marvel that is Going-to-the-Sun-Road during the early season while cars are restricted due to plowing operations. Regardless of where you ride, be sure to gather seasonal information such as available services, bicycling restrictions, area closures, and road and weather conditions.
Only those experienced at riding with heavy vehicle traffic in two directions should consider bicycling on Going-to-the-Sun Road during peak summer season.
A limited number of sites at Apgar, Fish Creek, Sprague Creek, and St. Mary are available for those arriving via bicycle or on foot (hiker/biker sites). Sites are shared, with a capacity of up to 8 people; larger groups must split up or use group sites where available. If hiker/biker sites are full or campers do not want to share a site, hikers/bicyclists must use regular unoccupied campsites. Read more about campgrounds on the Camping page.
Peak Season Restrictions
Visitor use patterns have expanded into the fall season, and Going-to-the-Sun Road is extremely busy until it closes. Peak season restrictions are in place due to increased vehicle congestion in this corridor with limited sight distance, exposed ledges, and sections of narrow, steep, and winding road. Restrictions are in effect on portions of Going-to-the-Sun Road from June 15 through Labor Day:
Are There Bike Trails?
Bicycles are permitted on all paved and unpaved roads in the park.
There are also four multi-use trails on which bicycling is allowed:

Spring Bicycling on Going-to-the-Sun Road
In Spring, portions of Going-to-the-Sun Road are open for hiking and biking, beyond the vehicle closure.
Road Crew Closures are in place Monday through Thursday during plowing. Visitors may advance to the Avalanche Hazard Closure when road crews are not working. Avalanche Hazard Closures are in place at all times. Progressive closure locations are determined weekly on Thursdays. Visitors are prohibited from going past the hiker/biker closures. Violators are putting their safety and the safety of our park rangers at risk and could face up to a $5,000 fine and up to 6 months in jail. You can find closure information on our Road Status Page.
