Lake McDonald, Glacier National Park: Largest Proglacial Lake

Lake McDonald at Glacier National Park, with crystal-blue water reflecting snow-capped peaks and a rocky shoreline.

Turquoise water mirrors the pine-fringed shoreline along a broad, glassy basin. This is a glacial lake formed by late-Pleistocene ice that left a U-shaped valley filled with meltwater. The water stays crystal-clear to the bottom, thanks to the cold depths and minimal plankton. The Going-to-the-Sun Road runs along the southern edge, offering easy roadside access to the lake's expanse.

This scenic alpine lake, the largest lake in Glacier National Park, offers kayaking & canoeing.
