Glacier in July: what the park service says

July is when Logan Pass gets its summer rules. In 2026 Glacier dropped vehicle reservations, but from July 1 to Labor Day it limited parking at Logan Pass to three hours, enforced around the clock, with a free timestamped permit from the kiosk on your dashboard. Three hours covers the Hidden Lake Overlook hike or the visitor center; a longer hike from the pass, such as the Highline Trail, meant taking the ticketed Logan Pass Shuttle from Apgar, Lake McDonald, Rising Sun or St. Mary. Check whether the park repeats this in 2027.
