Florida’s Everglades National Park is the third-largest national park in the lower 48 states after Death Valley and Yellowstone national parks. Visiting the Everglades is also a unique experience; unlike its western counterparts, much of this 2,400-square-mile park is covered in water and only accessible by boat. The vast tropical wilderness is home to a rich diversity of wildlife and filled with fun outdoor activities such as hiking, biking, kayaking and canoeing.
