On the southeast corner of Cypress Island, Secret Harbor is a deeply formed cove on the far southern end of Deepwater Bay (see article this website). All the uplands are closed to public access due to private property, hidden hazards from demolition, natural area recovery projects, and delicate new plantings of native vegetation. The water depth in Secret Harbor is shallow. Much of the cove becomes a large mudflat during lower tides. Use care when entering or leaving Deepwater Bay, currents and counter-currents can be strong during tidal changes.
