Muir Beach (the beach) is part of Golden Gate National Recreation Area and located in the small town of Muir Beach, California. Redwood Creek flows down to the ocean here, but slows down near the beach forming a lagoon, some ponds, and wetlands that are great for birding. There are hiking trails that branch out from Muir Beach in many directions inviting exploration of the headlands. Hike far enough and you’ll find the hidden beach called Pirates Cove.
