Garibaldi Lake, Alpine lake in British Columbia, Canada.

Garibaldi Lake is a turquoise alpine lake in Garibaldi Provincial Park, British Columbia, with its surface at nearly 1,500 m above sea level and a depth exceeding 250 m. It lies in a deep subalpine basin almost entirely ringed by mountains, with volcanoes along the north, west and south sides. The turquoise colour comes from glacial flour carried by meltwater from the Sphinx and Sentinel glaciers.

The lake basin formed from volcanic activity when a lava plug created a natural barrier that accumulated glacial meltwater over time. The surrounding landscape has been shaped by glacial movements and erosion across thousands of years.

The lake serves as a gathering place for outdoor enthusiasts in British Columbia who come to hike, camp, and photograph the mountain surroundings. People experience the landscape across all seasons and value it as a natural retreat from daily routines.

The hike to the lake begins at the Rubble Creek Trailhead and requires sustained effort over approximately 9 kilometers with significant elevation gain. Starting early and bringing weather-appropriate gear are essential since mountain conditions can shift quickly.

The lake's outflow normally seeps through cracks in The Barrier lava dam rather than over the surface; Rubble Creek emerges from springs at the dam's base. Only during spring snowmelt does a shallow channel carry surface water west into Lesser Garibaldi Lake and Barrier Lake, about 1.6 km from the main shore.
