Site details

Sebastian Inlet State Park straddles a man-made cut between the Atlantic and the Indian River Lagoon, with miles of shallow nearshore rock reefs starting just south of the inlet. Snorkeling and scuba are allowed everywhere except under the bridge and in the boat channel, and spearfishing is prohibited within the park. The shallow reefs hold tropicals, lobster and rays, but the inlet's powerful tidal flow makes timing around slack/high tide essential.
