Welcome to St. Mary, the breathtaking eastern gateway to Glacier National Park where the Rocky Mountains dramatically meet the open plains. You'll find yourself at the starting point of the legendary Going-to-the-Sun Road, with the stunning St. Mary Lake stretching out before you. It's the perfect basecamp for adventure, offering everything from gentle hikes like the family-friendly St. Mary/Virginia Falls trail (a 2.9-mile round trip) to scenic boat tours on the lake.
