Fodor's Expert Review Shell Key
Shuttles to this pristine paradise run out of Pass-a-Grille and Dolphin Landings, and you can catch them in the morning and early afternoon most days. If you do, expect some amazing snorkeling, shelling, and bird-watching. (You can also kayak or canoe here from a launch near Ft. De Soto.) Rustic overnight camping is allowed here in the part of the island not designated as a bird sanctuary. Watch for rip currents when swimming, as they can be pretty strong. Amenities: none. Best for: solitude; swimming; walking.
