Manatees, manatees, what can I say. Have you ever seen one outside of a Florida zoo? Here the manatees come into the small, spring river in the cooler months (mainly) to warm up. They also have a great large spring towards the end of the river and by the walkway that is an awesome experience free diving into. Thousands of gallons of spring fed water pumps from the bottom and it's a challenge to keep from not being pushed away. Get your snorkel and fins; great views. This is not the warm ocean but it is definitely refreshing.
