The Everglades is many things to many people, but above all else, it is a wilderness-1.5 million acres of the most extraordinary and unique habitat. 1,100 species of plants and 350 species of birds live here for at least part of the year, and some of those species live nowhere else on earth. We'll journey into the Everglades on foot, by airboat, on a helicopter and by kayak to see what secrets this wild space is hiding.
