Keyhole Falls

Keyhole Falls is a waterfall on Lillooet River in British Columbia that spans about 30 meters across and drops about 37 meters into a wide basin carved in the rock. The water flows into a natural bowl shape created by erosion, forming the distinctive keyhole appearance.

The falls originated after Mount Meager erupted about 2350 years ago, creating a volcanic dam across the river valley. The Lillooet River then carved through this barrier over time, forming the waterfall we see today.

The name comes from how the waterfall resembles a keyhole shape, created as rushing water has carved through rock layers over countless years.

Access is closed from April through November due to seasonal hazards in the area during those months. Check local regulations before planning a visit to understand what restrictions may apply.

The falls receive water from glacial melt originating in two separate glaciers located in the surrounding mountains. This meltwater contribution gives the falls their powerful flow and dramatic appearance throughout the year.
