Three Sisters Falls is a three-tier waterfall on Boulder Creek in Cleveland National Forest, reached by the rebuilt Three Sisters Trail from Cha'chaany Hamuk Trailhead on Boulder Creek Road. The 4.5-mile round trip drops about a thousand feet and then climbs the same slope in full sun; the Forest Service often closes it in extreme heat.
