Why not take a swim with real wild manatees at Crystal River with these peaceful loving animals. Equipped with a wetsuit and a snorkel a boat will take you out to look for for manatees. Once the captain finds a playful family of manatees, you can get off the boat and swim with them. Usually it doesn't take long to find manatees since they enjoy being close to humans.
The best time for this adventure would be from October to March when these large marine mammals are spending the winter in the warmer waters of Crystal River and are leaving again at the end of winter. Some sea cows even remain throughout the year so that these snorkeling trips can be offered all year around.
