Stillwater Cove, Protected inlet at Sonoma Coast, California.

Stillwater Cove is a sheltered inlet along the Sonoma Coast with rocky shores and sandy patches along the waterline. The bay opens to the south and is enclosed by rocky outcroppings that help protect it from heavy ocean swells.

Stillwater Cove lies between Fort Ross and Salt Point State Park, a stretch of Sonoma County coast where the cove was used for abalone harvesting. In 1947, some scenes of the film The Ghost and Mrs. Muir were shot at the cove. The California Coastal Commission later designated it an Area of Special Biological Significance.

Red abalone is hunted in the cove, and the California Coastal Commission has declared it an Area of Special Biological Significance. Scenes of the 1947 film The Ghost and Mrs. Muir were filmed here. The cove lies between Fort Ross and Salt Point State Park and is open to the public.

The cove lies between Fort Ross and Salt Point State Park, with Stillwater Cove Regional Park adjacent; a nearby ranch sits close by. It faces south and is shielded from northwesterly winds, so only large winter northwest swells reach the water. Depths run from about 9 m to 14 m, and around 12 m near the Pescadero rocks.

The cove's shape creates a natural barrier that blocks most northwestern winds year-round. Only in winter when large swells form offshore do substantial waves reach its waters.
