Fishing at Rio Del Mar State Beach on a winter afternoon

Rio del Mar neighbors Seacliff State Beach, which features the remains of the cement ship, the SS Palo Alto. The ship was launched May 29, 1919. It was too late for duty in World War I, and after the war was beached as an entertainment boat, with amenities including a dance floor, a swimming pool and a cafe. The SS "Palo Alto" historically adjoined the beach by a fishing pier which was heavily damaged in the January 2023 storm and subsequently demolished.
