Sebastian Inlet State Park is a Florida State Park located 10 miles south of Melbourne Beach and 6 miles north of Vero Beach, Florida. The park lies on both sides of the Sebastian Inlet, which forms the boundary between Brevard and Indian River counties. The land for the park was acquired by the state of Florida in 1971. In 2010, it was the second most visited state park in Florida.
The park mainly provides leisure activities, particularly fishing from both its Atlantic and Indian River shores; fishing jetties extend from both sides of the inlet into the ocean. There are facilities for swimming, surfing, snorkeling and scuba diving from the 5 km (3.1 mi) of Atlantic Beach. Boats can be launched into the Indian River, and there is a marina complex at the north end of the park. Camping is permitted in designated area.
Wildlife is abundant in the park, and the casual visitor can reasonably hope to see ospreys and many species of shorebird. Sea turtles nest in the park, and visitors during the summer may make reservations for a nighttime foray to observe nesting Loggerhead Turtles. The park also contains two museums: McLarty Treasure Museum and Sebastian Fishing Museum.
