One million people visit the Everglades every year to observe its precious ecosystem of tropical wading birds, Florida panthers, crocodiles, and manatees. In the continental United States, it is the third largest park next to Yellowstone and Death Valley at 1.5 million acres and is the largest wilderness east of the Mississippi River. The best way to take it all in is to bike along the seven-mile Long Pine Key Nature Trail where you can see everything from wild turkeys to black bears. 

Don't Miss: The Wilderness Waterway is a 99-mile maze frequented by canoers, kayakers, and powerboaters that takes at least eight days to complete by paddle. But the accommodations are worth it. Sleep at beachfront campsites if you can find them or in chickees – wooden platforms built by the National Park Service – that sit above alligators lurking in the swamps below.
