John Pennekamp Coral Reef State Park: Add some marine biology to your camping voyage by seeing coral reefs from a glass-bottom boat or get more up close and personal with a snorkel tour. The park has camping, canoeing and kayaking, nature trails, a visitor center with an 30,000 gallon aquarium and small museum and offers clean facilities and concessions. The short road trip to Key Largo is its own detour through nature and Florida history as you cut through the Everglades. (Mile marker 102.5, Key Largo. 239-451-1202.)
