About St. Mary Campground
St. Mary Campground, on the east side of Glacier National Park along St. Mary Lake, features 148 sites ideal for tents and small RVs. Proximity to the St. Mary Visitor Center and Sun Point Nature Trail makes it perfect for families. At 4,484 feet elevation, nights dip to 40°F in August. Secure reservations early; first-come sites available but competitive. Adhere to NPS rules on quiet hours (10 PM-6 AM) and bear-aware camping to protect this pristine area.
Safety Considerations
Swift, icy St. Mary River poses drowning risks; NPS warns of mammalian diving reflex in waters under 80°F, causing gasp reflex and heart strain. Avoid crossing near Baring Falls, where currents exceed 10 mph. Black bears frequent campsites; use metal lockers for all scented items, including toothpaste. Layer synthetics like Patagonia Capilene over cotton to combat sudden squalls off the Continental Divide. Photographers on shorelines slip on algae-slick rocks; use microspikes if needed. Wildfire smoke from nearby valleys can impair breathing; carry N95 masks. Mountain lions rarely appear but target solo campers at dawn; travel in groups and keep kids close.
Boaters on St. Mary Lake face 4-foot wind waves; secure paddles and wear PFDs. Check ranger station for trail closures due to goat activity on Otokomi Lake Trail.
