There are some 31 miles of the Florida National Scenic Trail within Big Cypress National Preserve. From the southern terminus, which can be accessed via Loop Rd, the trail runs 8.3 miles north to US 41. The way is flat, but it's hard going: you’ll almost certainly be wading through water, and you’ll have to pick through a series of solution holes (small sinkholes) and thick hardwood hammocks.
There is often no shelter from the sun, and the bugs are…plentiful. There are three primitive campsites with water wells along the trail; pick up a map and a free hiking permit (required) at the Oasis Visitor Center. Most campsites are free, and you needn’t register. Monument Lake has water and toilets.
