American Pro Diving Center, Crystal River

American Pro Diving Center helps visitors and locals explore the clear, teeming waters of Florida with year-round manatee tours and diving adventures. All-equipment-included manatee snorkel tours in Crystal River let snorkelers rub flippers with the rivers' large population of resident sea cows. In-water guides keep the experience safe and fun for both manatees and people, and snorkelers swim in between the gentle creatures, giving them a gentle pat or a canister of whisker wax.

For deeper subterranean adventures, the center offers classes that range from Discover Scuba Diving to full PADI open-water certification, in addition to specialty courses on rescue and wreck diving. Divers can plunge into one of seven diving excursions, including night dives in Rainbow River or mermaid line dancing in the lost city of Atlantis.
