Glacier in March: what the park service says

March at Glacier still runs on the winter setup. The 2026 ranger snowshoe walks were scheduled through March 15, and the park says most services in and near it do not reopen until late May or early June, so come self-sufficient and book a room outside the park. Clearing winter snow off the park's roads takes two to four months, and only the lower part of Going-to-the-Sun Road stays open all year. Primitive camping is open year-round at the Apgar and St. Mary campgrounds, and a night in the backcountry needs a wilderness permit. The park also notes that wildlife, bears included, is very active in spring, so carry bear spray.
