Campground Overview
Introduction
St. Mary Campground is the largest campground on the east side of Glacier National Park and is open year-round. Activities such as interpretive programs, book sales, and shuttle service tours are located at the nearby St. Mary Visitor Center. St. Mary requires a reservation throughout the season. Though shade may be sparse, aspen trees grace St. Mary Campground with soothing sounds from spring and summer breezes, and colorful splashes of yellow late in the season.
Campsite Details
Operating Hours
St. Mary operates year-round. All sites require reservations during the spring, summer, and fall. A portion of the campground is open during the winter months in primitive status. Reservations are NOT required in the winter.
Weather
Glacier's weather is highly variable and can be extreme. Warm days and cool nights are the norm in summer. Even when it's in the 80s and 90s in the daytime it can cool down into the 40s at night. Hikers setting out on a warm summer day, should still bring along rain gear and lots of extra clothing. Dressing in layers is key to a comfortable visit all year long.
