Crystal River, Florida, may be the world’s only manatee town.
While the world has plenty of college towns and ski towns and government towns, this town of just over 3,100 has a booming economy based on… sea cows. That’s because the consistently warm waters in Kings Bay — which runs through Crystal River — make it a hotspot for manatees in the winter. And it is the only place in the world where you can get right in and swim alongside them.
