Aquatic park is a San Francisco Maritime National Historical Park. Non-motorized boats and sail/auxiliary boats may anchor here overnight, with the correct permit. The cove is close to Fisherman's Wharf and other famous San Francisco waterfront sights.

Swimmers can enjoy this protected cove and private beach for easy access.  Swimming in the San Francisco Bay can be a challenging environment thanks to strong tides, boat traffic, sea life, and water temperatures ranging from under 50°F in the winter months to the low 60°F over the warmer months.
