Sebastian Inlet State Park occupies 755 acres on both sides of Sebastian Inlet along Florida’s Atlantic barrier island coast, linking the Indian River waterway with the ocean. Acquired by the state in 1971, it combines maritime history with heavy recreational use. The area is tied to the 1715 wreck of a Spanish fleet, and the survivors’ camp site is recognized on the National Register of Historic Places; artifacts from that episode are displayed at the McLarty Treasure Museum. Known for fishing, boating, swimming, surfing, and diving, the park also supports ospreys, shorebirds, and nesting sea turtles, and became one of Florida’s busiest state parks.
