Active Pursuits

Biking--Opportunities for biking in the park are limited, since bikes may be ridden only on established roads, bike routes, or in parking areas, and are not allowed on trails. Restrictions apply to the most hazardous portions of Going-to-the-Sun Road during peak travel times from around mid-June to Labor Day; call ahead to find out when the road will be closed to bikers. During low-visibility periods caused by fog or darkness, a white front light and a back red reflector are required. A few campsites for bicyclists are held until 9pm at Apgar, Sprague Creek, Fish Creek, Many Glacier, Two Medicine, Avalanche, Rising Sun, and St. Mary Campgrounds, for $3 per person.

From June 15 to Labor Day, bikes are prohibited between Apgar and Sprague Creek campgrounds between 11am and 4pm in both directions, and from Logan Creek to Logan Pass (eastbound) between 11am and 4pm. It takes about 3 hours and 45 minutes to ride from Sprague Creek to Logan Pass.
