St. Mary Falls

St. Mary Falls drops 35 feet in three distinct tiers where Virginia Creek meets the St. Mary River, each tier fanning wider than the last until the water spreads across the full width of the rock face in a frothing curtain. The milky turquoise color — from glacial flour suspended in the water — gives the falls an otherworldly glow, especially in the afternoon when sunlight penetrates the canyon. A sturdy footbridge at the base puts you within arm's reach of the spray.

The trail descends 0.8 miles from the St. Mary Falls shuttle stop, dropping about 260 feet through dense spruce forest to the river and falls. The return climb is the only challenging section of this otherwise gentle hike. Most visitors continue an additional 0.7 miles upstream to Virginia Falls, making for a 3.1-mile round trip with about 470 feet of total elevation change.

June through September offers the best conditions, with glacial melt keeping the falls strong all summer. The free park shuttle system makes access easy and eliminates parking stress during peak season. This is consistently rated one of the top five hikes in Glacier and draws crowds — an early start is essential for a peaceful visit.
