Best Time to Drive Going-to-the-Sun Road: Monthly Plan
Going-to-the-Sun Road is a 50-mile mountain highway that crosses the Continental Divide at Logan Pass (6,646 ft) in Glacier National Park. According to NPS.gov, the alpine section typically opens in mid-June and closes by mid-October, though weather can shift these dates. NPS IRMA data shows July as the busiest month across the park’s 2,893,996 annual visitors. Late June to early July is a better fit for waterfall seekers and wildflower photographers, compared to the crowded July peak when Logan Pass parking fills by 9:30 AM. Late September, an often overlooked window, delivers larch color with far fewer vehicles. This guide breaks down each open month by crowds, weather, road status, and trail access.
Quick answer: Best time?
Best Time to Drive Going-to-the-Sun Road: Monthly Plan opens with a decisive window: the full 50-mile Going-to-the-Sun Road usually runs from late June or early July through mid-October, per NPS.gov, and July is the peak month for visitors in 2026.
We recommend the late September window for fewer crowds and good alpine color. Logan Pass, Lake McDonald, and St. Mary are the key stops to plan around. According to NPS.gov and park data, driving the whole road without stops takes 2– hours, but plan a full day for views and hikes.

Is the road accessible?
Logan Pass Visitor Center and select pullouts have paved, wheelchair-accessible surfaces, and the 2026 ticketed shuttle includes ADA accommodations, per NPS.gov and shuttle operator guidance.
The Logan Pass boardwalk and the Trail of the Cedars are among the most accessible routes. Park data shows a 3-hour vehicle parking limit at Logan Pass effective July 1, 2026, which affects timing for accessible parking. Visitors and review themes suggest shuttle boarding areas at Apgar Transit Center and St. Mary are level but can be crowded; plan to arrive early for accessible spaces.
Based on the data, consider using the shuttle for point-to-point access if mobility limits make long walks difficult. For a lower-elevation, accessible viewpoint, try a paved pullout near Lake McDonald Lodge, and contact the park accessibility office before arrival for the latest accommodations.
