Sunset Falls is the final of the three waterfalls on the South Fork Skykomish River.

The falls drop 104 feet (32 m) in a long, narrow, powerful chute.

The river is thought to attain speeds of 60 kilometres (37 mi) an hour and the chute is nearly 300 feet (91 m) long.

Several local kayakers, most notably Rob McKibbin and Sam Grafton have run Sunset Falls successfully.

It is considered a class 6 rapid, with unavoidable and potentially deadly hazards.
