Sea Lion Caves

Sea Lion Caves is a connected system of sea caves and caverns open to the Pacific Ocean in the U.S. state of Oregon. They are located 11 miles (18 km) north of Florence on U.S. Highway 101, about midpoint on the 400 miles (640 km) of Oregon Coast. In this area, Highway 101 follows a steep and undeveloped seascape 300 feet (91 m) above sea level. Human access to the caves is through a gift shop building.
