The calm Gulf waters and pristine white-sand beaches of Fort Myers and Sanibel beg visitors to go island-hopping, and there's a string of barrier-island beauties to explore. Sanibel and Captiva are probably the best known, famous for their sublime sunsets and world-class shelling. They are just a short drive from Fort Myers over the Sanibel Causeway. With vacation rentals where you can stay overnight in island style, the more remote private-island community of North Captiva is three miles offshore and can be reached via a short ferry ride from Pine Island. Useppa is another private-island community accessible by boat only, with cottages for rent and beautiful beaches. For a fun lunch outing, hop over to the island of Cabbage Key, where there's a historic restaurant and a lively bar popular with boaters. Nine miles of blissfully undeveloped beaches await day trippers and overnight campers at Cayo Costa State Park, easily accessible by ferry from Sanibel, Captiva, Fort Myers, and other nearby locales.
