The largest subtropical wilderness in the United States and the third largest national park in the U.S., Everglades National Park is in a league of its own. First created to protect a fragile ecosystem, it is home to 36 endangered species including the Florida panther, American crocodile and West Indian manatee. Immersing yourself in the wild with a canoe or kayak excursion or an airboat safari is the best way to get inside the world of the Everglades. High season is December through March when temperatures take a dip and mosquitoes aren’t as bloodthirsty. The park has miles of biking and walking trails for all levels of skill, a 15-mile bike loop at the Shark Valley entrance, as well as tram tours year round. For a different view of the Everglades, consider staying near the southern end of the park in nearby Homestead or Key Largo.
