Fast Fact: Located within Florida’s famous Everglades National Park, the Marjory Stoneman Douglas Wilderness is the largest subtropical wilderness in the United States and the largest wilderness area of any kind east of the Rocky Mountains.
Within the Everglades National Park—the first park designated to protect an ecosystem as opposed to preserve beautiful scenery—lies a vast expanse of wilderness areas: nearly 86 percent of the park has been designated as wilderness.
The wilderness areas within the park have been dubbed the Marjory Stoneman Douglas Wilderness, and represent the largest wilderness area east of the Rocky Mountains. Within the area, nearly one-third of the land is submerged. Within those waters swim bottle-nosed dolphins, sea turtles, sharks, and manatees. On land, the elusive Florida panther wanders in search of food and shelter—today, its native habitat has been reduced to less than five percent of its original range.
