Perilous Falls is a unique canyon waterfall located on Dukes Creek a few hundred feet above Dukes Creek Falls and the confluence with Davis Creek. About 30 feet high, Perilous Falls tumbles in three distinct tiers through a narrow water-sculpted canyon. No established access to this waterfall exists along the Dukes Creek Falls Trail. It's best reached via a steep, unmarked scramble path on the west (opposite) side of Dukes Creek, branching off the unofficial trail to Middle Davis Creek Falls from FR 244.
