The Zmudowski State Beach is a state park and beach in Moss Landing, California. Some also refer to it as the “Hidden Beach”, being relatively less known by the public.

Named after Mary Zmudowski, a Watsonville schoolteacher who used to own the property where the park stands today, the Zmudowski State Beach was donated to the state in the 1950s. It is best known for fishing. It features the Pajaro River estuary, where a natural preserve is also established. Visitors and anglers would enjoy catching sole, flounder, halibut, perch, kingfish, jacksmelt, salmon, steelhead, lingcod, cabezon, and even rockfish at times around here. Birdwatching and horseback riding are also popular here. Water activities can be hazardous, though, because of strong rip currents and undertow.
