The Saint Mary area of Glacier National Park is one of the most beautiful parts of the Park. It is from the Saint Mary entrance that you start your drive along the Going-to-the-Sun Road, one of the most scenic drives in North America. The St. Mary area is also home to many beautiful lakes and plenty of waterfalls.

Saint Mary Falls is one of two waterfalls that can be accessed from the St. Mary Falls trailhead. From the shuttle stop where you’ll pick up the trail to St. Mary Falls, you can also hike a bit further on the same trail and enjoy views of Upper Virginia Falls.

The hike is a relatively easy 2.9 miles out and back. It takes most visitors about 90 minutes to complete the roundtrip hike to both St. Mary and Upper Virginia Falls.

St. Mary Falls is one of the most impressive and beautiful falls in Glacier National Park. St. Mary River cuts its path through the hard rock, creating a dramatic canyon.

The falls sit within the canyon and tumble over three separate benches. Even in the peak of summer visitors to St. Mary Falls can hear the roar of the water tumbling down the rock. 

St. Mary Falls is frequently photographed, and the trail is very popular. It is recommended that if you want a more peaceful experience you enjoy the hike early in the morning. This is a great time to enjoy the Park’s wildlife, easier parking, and fewer people on the trail.
