Diving and Snorkeling

Learn how to dive in a day, get your Florida Keys scuba diving certification, or take a specialty scuba class right here in Marathon. Turtle Island Watersports employ the finest captains and dive professionals, so you’re in safe hands.

Water Craft

The best way to enjoy our island paradise is from the water. Try kayaking, rent a Wave Runner or Hobie Cat, or witness our amazing sunsets on aboard a 40-foot sailing catamaran.

Eco Tours

Discover the tropical wildlife that makes the Keys a true paradise. Jump aboard a Wave Runner or kayak and join Turtle Island’s guided eco tours.

Pool Adventures

You don’t have to venture far for Florida fun. Our lush tropical lagoon swimming pool is home to a wide variety of activities, all developed by our Adventure Concierge. Try snorkel lessons, watch a scuba demo, or let the kids enjoy a bubble-blowers’ adventure.

*Please note: The last watersports reservations of the day are taken at 4:00 p.m. and the watersports reservation tent closes at 5:00 p.m. If reservations are not made by 4:00 p.m., the tent may close earlier.
