🐾 Dogs & Pets at Cayo Costa State Park
Park policy: Cayo Costa's own amenity listing states plainly that pets are allowed here, so the island is not one of the Florida parks with a blanket pet ban — but it keeps them off the beaches and out of the cabin area. Getting a dog there means arriving under your own power: ferry service, tram operations and overnight accommodations have been unavailable since July 28, 2025, and the park is open daily 8 a.m. to sunset for visitors with private vessels.
