"Most people come to the sleepy little Gulf Coast Florida town of Crystal River, about an hour north of Tampa, to swim with the many, many manatees that descend on spectacularly beautiful and cerulean freshwater springs like Three Sisters within the Crystal River National Wildlife Refuge. The Plantation on Crystal River, an old-school hotel with a lagoon-style pool and rooms right on the river, also runs manatee tours right from its watery doorstep."
