Stillwater Cove is an inlet between the museum and town of Fort Ross, California and Salt Point State Park.

Stillwater Cove is shielded from northwesterly winds, facing southward along the California coast.

It has a favorable geographical location which lets only large winter northwest swells propagate into the cove's repaired environment, refracting around Pescadero Point.

The cove's depth ranges from ~9 m to ~14 m, while the region directly surrounding the Pescadero rocks is ~12 m deep.

Stillwater Cove has been declared by the California Coastal Commission an “Area of Special Biological Significance”.
