Montana
Going-to-the-Sun Road
Going-to-the-Sun Road climbs from Lake McDonald over Logan Pass to the St. Mary Valley. When it is fully open, it is one of the most concentrated scenic drives in the national park system. When it is not, you do not improvise a snowed pass in a rental car. Plan the trip around the park’s current vehicle reservation system and the road status page. Logan Pass parking fills. The Highline Trail and Hidden Lake Overlook are the usual hike add-ons; both involve alpine weather and, early season, snow. This is a Montana trip that rewards two nights on each side of the divide more than a single continuous drive.

Frequently Asked Questions
When does the road open?
Snow removal usually finishes in late June or July, sometimes later. There is no fixed calendar date you can trust from a previous year. Use the NPS road status page the week you travel.
Do I need a reservation and a pass?
Glacier has used a vehicle reservation in addition to the park entrance pass. They are not the same document. Read the current year’s system.
