Lake McDonald is Montana's largest lake, drawing visitors with its famously colorful pebbled shores, crystal-clear glacial waters, and sweeping mountain scenery inside Glacier National Park.
Lake McDonald sits at roughly 3,150 feet elevation in the western reaches of Glacier National Park, carved by glacial activity over thousands of years. At nearly ten miles long and nearly a mile wide, it is the largest lake in the park, and its depth reaches around 472 feet in places. The lake's vivid multicolored stones are polished quartzite and argillite, carried and smoothed by glaciers over millennia.
Visitors come to swim, fish, kayak, and simply walk the rocky shore. The historic Lake McDonald Lodge, built in 1914, anchors the southeastern end and offers a rustic base for exploration. Guided boat tours depart from the lodge dock throughout the summer season.
Nearby trails reward those who venture beyond the shoreline. The path to Avalanche Lake begins just a short drive away and passes through one of the finest stands of old-growth cedar in the region. Wildlife sightings, from bald eagles overhead to deer along the forest edge, are common throughout the area.
Lake McDonald earns its place among Montana's most beloved natural destinations through sheer, unhurried beauty that rewards every kind of visitor.
