Sleeping on your own private island..
Shell Key is one of the larger uninhabited islands off of the west coast of Florida near St. Petersburg. It is managed by the county, and all campers wishing to stay must get a (free) camping permit from Pinellas county. The key itself can only be accessed by water and you must carry in/out everything as there are no bathroom facilities available and all campers must bring a port-a-potty.
Once you decide to stay, you will be amazed by the white sands, abundant wildlife, crazy beautiful sunsets all while pitching your tent among the seagrass in one of the designated camping spots. On the west coast of the island is the blue waters of the Gulf of Mexico, while only footsteps away is the lush waters of the Intercoastal waterway. You can enjoy most water activities as well as what nature has to offer from bird and dolphin watching to fishing and hiking the almost 2 mile long island.
