Saint Mary Lake, located in Glacier County, Montana within Glacier National Park, is the park's second-largest lake and offers paddlers a stunning alpine experience. This 10-mile-long, glacier-fed lake sits at the eastern gateway to the park along the Going-to-the-Sun Road, surrounded by dramatic peaks including Little Chief Mountain, Mahtotopa Mountain, and Red Eagle Mountain.

**Access and Conditions** Paddlers can launch from the Rising Sun area on the lake's north shore or from other access points near St. Mary. All watercraft require an Aquatic Invasive Species (AIS) inspection before launching, with permits available from park rangers. The lake is typically accessible from late May through September, though exact dates vary with snowmelt and weather conditions.

**Paddling Character** Saint Mary Lake is known for its crystal-clear turquoise waters and dramatic mountain backdrops. The lake's finger-like shape creates a corridor flanked by towering peaks, offering unparalleled scenery. Wild Goose Island, the lake's iconic small island, is a popular destination for paddlers seeking photo opportunities and a unique close-up experience.

**Hazards and Considerations** Wind is the primary challenge on Saint Mary Lake. Mountain weather patterns create strong afternoon winds that generate significant chop and waves, sometimes reaching several feet. Early morning or evening paddles are strongly recommended for calmer conditions. Water temperatures remain extremely cold year-round (around 50°F or below), making immersion dangerous. Paddlers should wear life jackets, dress for immersion, stay within a safe distance of shore, and monitor rapidly changing mountain weather. The exposed nature of this alpine lake means limited shelter from wind once on the water. The combination of cold water, potential high winds, and remote location requires paddlers to exercise caution and proper preparation for wilderness conditions.
