It is the most rugged of the long-distance trails. The only section officially designated runs for 795 miles from Canada through Montana and Idaho to Yellowstone National Park. It is open to hikers, pack and saddle animals, and in some places, to off-road vehicles.
Some segments are open for use in other states.
This trail was conceived and initiated by James Kern who formed the Florida Trail Association in 1964. The trail will eventually extend from Big Cypress National Preserve in South Florida through Florida's three National Forests to Gulf Islands National Seashore in the western panhandle. It is especially delightful for winter hiking and camping, passing through America's only sub-tropical landscape. More than 1000 miles are completed and some 300 miles are officially open to public use. At the end of the Ice Age, about 10,000 years ago, glaciers retreated from North America and left behind a chain of moraine hills which defined the southern edge of the glaciers.
