Cayo Costa was a Cuban fishing rancho, then a quarantine station for Tampa-bound ships. Cabbage Key's inn was built in 1938 on a Calusa shell mound by the family of novelist Mary Roberts Rinehart. The Calusa built these mounds over 1,500 years without agriculture, living entirely on the estuary. Anchorage: Pelican Bay behind Cayo Costa is one of the best-sheltered anchorages on Florida's Gulf coast, with state park moorings. Cabbage Key has a small dock. Hazards: Shoal-draught navigation in Pine Island Sound; the passes run hard. This coast was badly hit by Hurricane Ian in 2022, verify current facilities. Más
