At Logan Pass, the highest point on the Going-to-the-Sun Road in Glacier National Park, the parking lot is notorious for filling up extremely early. During the peak summer months of July and August, the lot is typically completely full by 7:00 AM, and sometimes as early as 6:30 AM on holiday weekends. If you do not arrive by this time, you may find yourself circling for hours or being turned away by park rangers. Because this is the primary trailhead for the popular Highline and Hidden Lake Overlook trails, demand far exceeds the roughly 300 available spaces. To avoid the stress of parking, many savvy travelers use the free National Park Service Shuttle, which runs from the Apgar and St. Mary Visitor Centers. In 2026, the park continues to use a vehicle reservation system for the Going-to-the-Sun Road, but even with a reservation, a parking spot at the Pass is never guaranteed unless you are an early riser.
