Wilderness camping in the Everglades ranges from ground sites to chickees (raised platforms over the water). Permits are required for all backcountry sites and are arranged through the main visitor centers.
From November to April, backcountry camping permits cost $15, plus $2 per person per night; from May to October sites are free, but you must still self-register at Flamingo and Gulf Coast Visitor Centers or call 239-695-2945.
