McNears Beach developed a fishing industry in the 1870s. The McNear post office operated from 1897 to 1910. The name comes from the McNear Family, former owners of the land. The McNear Brothers, E.B. and J.A., moved to the beach site about 1870 and built two houses (which have since been demolished), a stable, warehouse and general store. The stable remains, and is now used as a Park Ranger Office operated by Marin County Parks. In 1970, the County acquired 55 acres at McNears Beach to create McNears Beach Park. Today, McNears Beach Park is a regional park offering a fishing pier, swimming pool, snack bar, sand volleyball court, picnic areas, and tennis courts.
