About Stillwater Cove
Stillwater Cove is a sheltered Sonoma Coast cove with a gentle beach entry, a rocky-to-sandy shoreline that changes with the tide, and kelp-covered structure farther out. It works well for training, relaxed shore dives, and longer swims to the outer rocks when you want more life and a wall-like profile. Parking, beach loading, and swell windows matter as much as the dive itself.
