Sanibel Captiva Map. Sanibel island has 15 miles of beaches, 22 miles of bike paths, abundant wildlife and the largest undeveloped mangrove ecosystem in the country. So there’s more to Sanibel island than just shells! Well, not technically. The island is actually made of shells.
They have it all wrong.... Panama City Beach is the BEST. White sand beaches.... Affordable attractions.... Best spring break and Thunder Beach not to mention the best beach ball drop. Don't waste your time with any other FL beach... Visit PCB today :)
