Crystal River runs at 22 °C all year, so when the Gulf drops in winter every manatee for miles moves in. Several hundred can be in the spring system at once. Snorkel only — scuba is banned here — and the rule is passive observation: float, keep your hands to yourself, never chase, never dive down onto one, and never put yourself between a mother and her calf. Parts of the springs are closed sanctuary and marked; they are closed for the animals' rest, not for the look of it. It is a metre deep, it is not a dive in any technical sense, and it is one of the great animal encounters anywhere.

Ninety minutes north of Tampa by road. Operators launch from Kings Bay; the boardwalk gives shore access at the refuge.
