Isla Blanca means 'White Island,' and the mile-long (1.6 kilometers) beach here is made of fine white sand. Though the park itself is primarily made for RV's, all visitors are welcome to take a dip in the gulf. Additionally, if you decide to stay on the beach, try to make a reservation and obtain one of the eight cabanas with marvelous views and sand right outside the door. Isla Blanca is a popular fishing and surfing destination.
