Looking for a high-energy water activity in Marathon? Discover the floating fun of The Lagoon on Grassy Key, with trampolines and climbing walls perfect for all ages. Dive into this unforgettable aqua adventure today!
The Lagoon in Marathon, Florida, is a watersports center offering a broad selection of lessons, rentals, and guided experiences across the Florida Keys. It provides cable wakeboarding with unique 2-point cable systems, kiteboarding and kite-flying courses, wingboarding, E-Foiling lessons, basic sailing instruction, and stand-up paddle activities including guided downwinders. The site also hosts a large floating aqua park, Rhum Runner at The Lagoon on Grassy Key, featuring floating trampolines and climbing walls for family-friendly fun.
Instruction spans beginner to advanced levels with options for private one-on-one lessons, goal-oriented advanced coaching, and combined classroom and on-water sessions. Specific programs include beginner cable reservations that mimic the feel of boat-towed wakeboarding, intro and advanced kite lessons with ground school, and tailored advanced cable reservations that allow riders to use larger features such as XL kickers and rails. Guided downwinders target experienced paddlers and kiteboarders and run with a small-group limit and shuttle service.
Safety and skill progression are emphasized through structured ground school, self-rescue techniques, and controlled practice sessions. Scheduling depends on weather for many offerings, and several experiences combine shore-side instruction with water time. Courses teach kite setup, control, board starts, upwind riding, power strokes, and self-rescue to promote safe progression on the water. Private and group bookings are available for families, solo travelers, and experienced athletes looking for targeted sessions. Advance reservations are recommended.
