About this tour

Discover St Maarten’s one-of-a-kind underwater sculpture park, Under SXM, with the people who know it best — the creators, builders, and owners of the park itself. This 2-hour adventure begins with a short scenic 10 minute boat ride from Great Bay to Little Bay, where over 300 sculptures transform the seafloor into a breathtaking gallery teeming with marine life.

Your expert guide will join you in the water, sharing insider stories about the design, build, and installation of the park, while also pointing out fascinating sea life along the way. Snorkel gear and safety floats are provided, and optional digital underwater photos can be purchased onboard to capture your memories.

With three tours daily at 9am, 11.30am & 2pm and a meeting point just a 10-15 minute walk from the cruise ship terminal, this experience is designed to be easy, memorable, and stress-free. We guarantee you’ll always be back to your cruise ship or your sun lounger on time.
