Unique underwater experience - Under SXM is an incredibly special addition to the island—truly one-of-a-kind. Having snorkeled all around Saint Martin for over a decade, I can confidently say this underwater museum is unlike anything else here. Our guide, Derek, was outstanding. He not only led the tour with ease but had an amazing eye for spotting sea life that most of us would’ve completely missed. His passion for the project was infectious, and he did a fantastic job sharing the story behind the museum’s art as well as its significance to the local marine ecosystem. The price is more than reasonable—I would honestly pay double if it means supporting and sustaining such a meaningful and impactful experience. My husband and I are already looking forward to returning in the future to see how the reef continues to grow and evolve. Highly recommend this tour to anyone visiting the island!

A Magical Underwater Experience with Underwater SXM! - My time with Underwater SXM was nothing short of amazing! From the moment we arrived, the team made us feel welcome and completely comfortable. Their professionalism, kindness, and genuine love for the ocean really stood out. The underwater experience was peaceful, breathtaking, and unlike anything I’ve ever done before. Swimming among vibrant marine life and exploring the crystal-clear waters of St. Maarten felt like stepping into another world. The guides were knowledgeable, patient, and made sure we felt safe and relaxed the entire time. They also captured beautiful photos and videos that I’ll cherish forever. Whether you’re an experienced swimmer or just looking to try something new, Underwater SXM is an absolute must-do while on the island. It was easily one of the most memorable parts of my trip!

Magical experience - My wife and I did this trip and we both loved it. My wife is a keen swimmer, and at 81 years young, she found the trip to be enlightening and magical. We both did the photo package with Derek which was a wonderful add on and we shall treasure the pictures forever. A must do tour in St Maarten. Highly recommend.

Family fun! - Our family of four (two adults and two kids, ages 9 and 12) had the most unforgettable experience snorkeling the underwater sculpture park in St. Martin! This unique trip was the highlight of our holiday and something we’ll be talking about for a very long time! Swimming through this underwater gallery felt like exploring a sunken museum. The kids were fascinated by the statues and loved spotting the colorful fish weaving in and out of the artwork. We even saw a sea turtle swimming nearby! Everything was well-organized and safety-focused, but still relaxed and enjoyable. We felt completely at ease the whole time. Highly recommend this experience, there’s nothing quite like it!
