Similkameen Falls, Natural waterfall on Similkameen River, British Columbia, Canada

Similkameen Falls is a waterfall on the Similkameen River in British Columbia, about 25 km upstream from Princeton, just below the Pasayten River mouth. Over roughly 0.2 km the river drops about 25 feet through a canyon flanked by igneous rock walls up to 250 feet high. The first drop is a 5-foot chute no more than 3 feet wide, plunging into a deep pool.

Remains of an old bridge structure stand above the first cascade, showing where people once crossed the river. This structure marks a historical crossing point that served the area for crossing the waterway.

The name Similkameen Falls is a rarely used alternate name for Coyote Falls, a different waterfall further downstream in Washington State, so the two are sometimes confused. The river's name, and with it the falls' name, comes from the Similkameen, the Indigenous people of the valley.

The lower falls are visible from Highway 3 by looking upstream into the canyon. The upper sections are hidden from the road because the falls bend about 45 degrees below the first drop; they can only be seen from the canyon edge on the north side of the river.

The river channel narrows to just 3 feet wide at the first drop, forcing water through an extremely tight passage. This sudden constriction creates a powerful rush before the water spreads into a deep pool below.
