Three Sisters Falls

Waterfall · California

About this swimming hole

Three Sisters Falls drops in three tiers through a granite gorge in Cleveland National Forest, and the upper two pools are deep enough for swimming. The 4-mile round-trip hike is notoriously hot and steep — start at dawn and carry abundant water. Winter and spring flows make the falls spectacular; by late summer they slow to a trickle.
