There are two drive-in campgrounds accessible from the Homestead entrance of the park: Long Pine Key Campground and Flamingo Campground, according to NPS. Both accommodate tents and RVs. Hiking, biking, canoeing and kayaking opportunities in the huge park of more than 2,400 square miles will keep you entertained. In fact, you may have to use one of these options to reach most backcountry camping sites. Be on the lookout for manatees, alligators and crocodiles.
