Spend your day swimming or snorkeling at Florida's southernmost state park. A sprawling beach of sand and pebbles, and nearby breakwaters teeming with tropical fish, ensure great fun in the sun for both beachcombers and snorkelers. Known by the locals as 'Fort Zach,' or 'rocky beach,' our park boasts the best swimming on the island. Situated next to the main shipping channel, the currents here keep the water clean and clear. Snorkeling equipment can be rented or purchased at the concession located in the picnic area. Showers are available to rinse off after a relaxing day in the sun. Water shoes are recommended because of the rocky sea bottom. No lifeguards, swim at own risk.
