Keyhole Falls is the unofficial name for the largest waterfall along the Lillooet River in British Columbia, Canada. The falls are 115 feet (35 m) high and are a punchbowl type of waterfall.[1]

It is called Keyhole Falls because it resembles a giant old-fashioned keyhole.[1]


Keyhole Falls was formed when the Lillooet River was dammed with breccia from a Plinian eruption at the Mount Meager massif about 2350 years ago. The thick breccia soon eroded from water activity, forming Keyhole Falls. There was a massive flood when the water first broke through the breccia. The flood was big enough that small house-sized blocks of breccia were carried away during the flood.[2]

First Descent[edit]

Keyhole Falls was first descended by Spanish Kayaker Aniol Serrasolses.
