This foreboding world world seem the least appealing of the natural riches in Florida, where white-sand beaches line an immense coastline.  

Yet every year tourists venture beyond that cypress to experience one of the most intimate encounters with nature that you can find: a swamp walk. There's no airboat here. No Kayak. No boardwalk. Just old shoes, a walking stick and mucky brown swamp water rising, at times, up to your thighs.
