Steep Ravine Hot Springs occupies a dramatic coastal setting in Marin County, California, where rugged sea cliffs meet the redwood-draped headlands of the Mount Tamalpais State Park watershed. Perched above the Pacific on a shoreline known for its wild beauty and perpetual sea mist, this hot spring resort sits within one of the most scenically intense stretches of the Northern California coast.

The thermal water at neutral pH flows into a small, rustic tub shelter that has long attracted those willing to navigate the narrow coastal path. The experience is deliberately unpolished: bare wood, crashing surf within earshot, and the vivid contrast between warm water and salt-laden ocean air. Access is limited, lending Steep Ravine an air of exclusive discovery. For those who reach it, the combination of thermal immersion and elemental Pacific scenery is memorably restorative.

Insider tip — Steep Ravine is a Marin County (California) state park on the Pacific cliffs, at the foot of Mount Tamalpais. The site is best known for its isolated cabins and oceanfront campsites; the presence of a notable thermal spring there is uncertain, and it may be only a minor geothermal seep.
