Elaho River, River in Coast Mountains, British Columbia, Canada

Elaho River is a mountain stream in British Columbia that flows through forested terrain and rocky canyons in the Coast Mountains. The water originates from glacial sources and travels through a landscape of steep valleys and dense woodland before reaching lower elevations.

The Elaho River runs about 70 km from the outlet of an unnamed lake fed by the Elaho Glacier to its confluence with the Squamish River. Its largest tributary is Clendinning Creek, followed by Sims Creek; between Marlow Creek and Clendinning Creek the river cuts through Elaho Canyon. The Elaho is larger than the Squamish when the two meet and is subject to flash flooding.

The river's name comes from the Squamish language, and its course lies in the traditional territory of the Squamish Nation. Today the Elaho is known for whitewater rafting and kayaking, especially the run through Elaho Canyon between Marlow Creek and Clendinning Creek. Its largest tributary is Clendinning Creek, followed by Sims Creek.

The river offers different difficulty levels with rapid sections that flow better during warmer months when water levels are favorable. Visitors should go with proper boats and experienced guides who know how to navigate the challenging current conditions.

The Elaho is larger than the Squamish River at their confluence, and it is prone to flash flooding. Its largest tributary is Clendinning Creek, which joins after the river runs through Elaho Canyon; Sims Creek is the second largest. The river begins at an unnamed lake fed by the Elaho Glacier.
