3 Day Trips from Key West: Islamorada, Dry Tortugas & Key Largo | Condé Nast Traveler

"This nonprofit organization is dedicated to rescuing dolphins, manatees, and other sea mammals, and visitors to the sanctuary can assist by doing anything from observing their resident animals from the dock and watching the team at work, to shadowing a trainer for the day. But the highlight for most will be getting to take a swim with the dolphins. Some of the other programming here shows visitors how to care for the animals; depending on the day and dolphin, you might see how a dolphin ultrasound is performed, or how to brush a dolphin’s teeth." - Jennifer M.
