Twin Falls

Part of Glacier NP’s glacially carved landscape that records Belt Supergroup geology and the Lewis Overthrust context, with U-shaped valleys and cirques nearby.

Glacially sculpted terrain in Glacier National Park, underlain by Belt Supergroup rocks within the Lewis Overthrust domain. Twin Falls demonstrates alpine glacial hydrology: outlet streams from surrounding peaks and No Name Lake feed two cascades that descend about 80 feet into the Two Medicine Valley. Nearby Pumpelly Pillar is a prominent glacially carved pillar that helps illustrate the landscape’s geological history. The trailhead sits around 5,180 feet in elevation, with the hike peaking near 5,320 feet.

From Two Medicine Lake area, access Twin Falls via trails from the West End Boat Dock or South Shore Trailhead. Take the shuttle boat across Two Medicine Lake to reduce distance, then follow the Twin Falls trail to the cascades.

Twin Falls trail connects with trails toward Upper Two Medicine Lake; combining hikes is common with boat shuttle or longer treks.
