Located in the community of Mussel Shoals, Mussel Shoals Beach is a long and narrow beach situated in the northern part of Ventura County. A part of the beach is lined with a row of houses situated side-by-side and has light brown sand. The beach also has a gradual slope, and parts of Mussel Shoals Beach have been fixed with rocky embankments to prevent erosion. The southern part of the beach is narrower than its northern part, and there are also patches of vegetation on the beach. An artificial islet spread over two acres called Rincon Island (which was previously used for extracting oil) is present near Mussel Shoals Beach. This island is located around 3,000 feet away from mainland Ventura County and is connected to the mainland via an oil pier (known as Richfield Pier) situated near the southern end of Mussel Shoals Beach. However, it is important to note that both Richfield Pier and Rincon Island are currently off-limits to public.
