Darwin Falls, Perennial waterfall in Death Valley National Park, California, United States

Darwin Falls is a year-round waterfall in Death Valley National Park, California, flowing through a narrow desert canyon with multiple cascade sections. The water drops approximately 80 feet total, with the lower portion being the most accessible for visitors to view.

The waterfall was named after Darwin French, a nineteenth-century rancher and explorer who operated mining ventures in the region. This early settler's name has remained attached to the location since that era.

The name Darwin runs through the whole area: the falls, the adjacent Darwin Falls Wilderness, the town of Darwin and nearby features all honour Darwin French (1822–1902), a rancher, miner and explorer. The canyon's water supports quail and small fern gullies, and the grotto between the upper and lower falls is a spot hikers stop at.

Since 2023 flooding washed out Old Toll Road, visitors park on State Route 190 about 0.25 miles west of Panamint Springs and walk roughly 2.5 miles to the trailhead; the road is closed to vehicles indefinitely. From there the canyon trail to the lower falls runs 1 mile each way and turns moderately difficult near the end. The full round trip from the highway is about 7 miles with over 700 feet of elevation gain. Reaching the upper falls needs moderate climbing with some exposure.

This waterfall is one of only four year-round water sources across the entire 3-million-acre park. This rarity makes it an exceptional feature in an otherwise extremely dry landscape.
