The Original Underwater Sculpture Park Snorkel Tour
Book on Viator →Operated by Under SXM · Bookable on Viator
Snorkeling among art feels like science fiction. This Under SXM tour is interesting because you snorkel right over 300 underwater sculptures at about 15 feet, guided by the park’s own creators and owners. I really like the short 10-minute boat ride (less travel, more water time), and I like that the guide explains how the reef sculptures were built and installed, not just what you’re looking at. One possible drawback: in cloudy conditions, both the sculptures and the fish can be harder to spot.
You also get a cruise-friendly setup. The tour runs three times daily (9am, 11.30am, and 2.30pm), lasts about two hours, and keeps groups small (max 18). It’s designed to be stress-free: you have gear sorted, safety floats provided, and a plan to get you back on time.
Logistics are simple too. You use a mobile ticket, meet near Bobby’s Marina (two blue sculptures), and the meeting point is a 10 to 15 minute walk from the cruise ship terminal. Just note it is not recommended for non-swimmers.

Key highlights you should care about
- Park creators as guides: You’re led by the original designers/builders/owners, so the stories are specific to how and why the park was made.
- 300 sculptures at snorkel depth: The art sits around 15 feet down, which means most snorkelers can float and watch without constant “hunting.”
- Small group size (18 max): Less crowding in the water, more attention when you need it.
- Quick boat transfer: A short scenic ride gets you from Great Bay to Little Bay fast.
- Gear plus safety floats included: You don’t have to bring your own snorkel kit.
- Optional digital underwater photos: You can buy professional digital shots onboard for a ready-to-share souvenir.
Under SXM: the underwater art park that actually functions like reef
Under SXM is one of those rare snorkel attractions where the “wow” isn’t just the photos. Yes, it’s a sculpture park, but the real point is that it acts like a reef structure. You’re floating above man-made forms placed to support marine life, and the whole experience feels like a working habitat that also happens to be art.
The scale helps. You’re snorkeling over 300 reef sculptures, and they’re positioned so you can see them while staying near the surface. Instead of trying to swim around searching for one subject, you get a whole gallery you can slowly scan. That matters if you’re not the strongest swimmer or you just want an easy rhythm.
The guide angle makes a big difference too. Since the tour is created and run by the park’s original designers, builders, and owners, the explanations tend to be grounded in practical details—how installation was done and what they expected to happen once the sculptures were in the water. When you hear that kind of context, the park goes from “cool stuff” to “I get why it’s arranged that way.”
If you’re a fan of sea life, you’re in the right place. You should expect to see fish cruising near the structures, and you may spot things like squid and puffer fish depending on conditions and what’s moving around that day. Visibility plays a role, so on glassy days the whole area usually looks more readable.

Getting to the water: Bobby’s Marina meeting point and the short transfer
This tour is built for cruise timing, and you’ll feel it right from the start. You meet at Bobby’s Marina in Philipsburg, at the two blue sculptures, and your walk from the cruise ship terminal is typically 10 to 15 minutes. That’s close enough that you’re not spending your day budgeting for taxis or long shuttles.
Once you’re at the marina, you head out by boat and keep it simple. The ride is about 10 minutes, from Great Bay to Little Bay. That short transfer is a smart design choice for snorkel tours: it limits time on the water before you even gear up.
The boat setup also helps with comfort. You get enclosed totes to keep your stuff dry, so you’re less stressed about towels, phones, and dry clothes. The boat ride itself tends to be calm and scenic, and it’s long enough for everyone to settle in before you reach the snorkeling area.
One thing to keep in mind: the tour does not provide road transportation to the boat pick-up location in Philipsburg. If you’re not already near the meeting point, you’ll need to handle that part yourself. For most cruise schedules, though, the short walk and cruise-friendly timing are a big win.
How the tour works: gear, safety floats, and what you do in the water
Plan on an easy-flow experience. You’ll get snorkeling gear and safety floats provided, and the guide joins you in the water. That matters because you’re not thrown into a free-for-all. The guide is there to explain what you’re looking at and to keep you pointed toward the best parts of the sculpture area.
The sculptures are around 15 feet below your floating position. You don’t need to be a spearfishing-level diver. The expectation is that you’ll float above and look down. If you’re new to snorkeling, that surface-floating style is often less intimidating than a deeper-water plan.
The group size is limited to 18, which usually keeps the experience from feeling crowded. In practical terms, it’s easier to manage your breathing, stay aware of where people are positioned, and avoid the chaos that can happen when lots of snorkelers pile into the same small space.
Not recommended for non-swimmers is clearly stated for a reason. Even with floats, you’ll be in open water. You’ll want basic comfort in the water and the confidence to follow instructions.
If you’re concerned about boat steps or getting on and off safely, you’ll be glad this tour is run with a safety-first mindset. I’ve seen praise for staff who help older visitors handle the boarding process smoothly, which tells me the team is used to supporting different comfort levels.
Stop at Under SXM: what you’ll see over 300 sculptures
This is the main event: your hour-long snorkeling session over the Under SXM sculpture field. When you enter the water, the first thing you’ll notice is how your brain switches from “searching for something” to “reading a scene.” The structures are spread out enough that you can take your time, but close enough that you don’t feel like you’re swimming through empty ocean.
The big advantage of this location is depth and visibility. Because the sculptures are about 15 feet down, they’re reachable by eye from the surface, which lets you conserve energy. You can float and scan, then pause and look longer when something interesting moves near a statue or opens into a shadowy pocket.
You’ll also want to practice slow, calm movement. Quick flailing doesn’t help anyone here. The fish tend to cruise around structures rather than darting everywhere, so the more smoothly you move, the more you’ll notice patterns—like fish hanging out near edges, or larger movement circling the sculpture forms.
What to expect in terms of sea life: there’s a strong chance you’ll spot multiple fish species. Squid have been sighted, as have puffer fish and other varieties, though what you see depends on the day. If it’s overcast or cloudy, you might find the sculptures and animals less distinct. The good news is you’re not relying on one tiny highlight; even when visibility softens, the overall “art museum underwater” idea still comes through.
Also, remember the sculptures are artificial reef structures honoring the history and culture of St Maarten. So while it looks like fantasy, it’s also a cultural experience. You’re looking at symbols and forms placed with intention, and the guide’s stories can help you connect what you see with what the creators were aiming for.
Sea conditions and photo options: turning the day into a souvenir
Visibility is the biggest factor that can change your day. If conditions are cloudy, you may struggle to see both the sculptures and fish clearly. That doesn’t mean the tour is wasted, but it does mean you should adjust your expectations: instead of crisp, close-up viewing, you might focus on silhouette shapes and general activity near the structures.
When visibility is better, the experience tends to feel more precise. You can track fish movement along the sculpture edges and recognize more detail in the forms. The difference is real enough that it’s worth keeping an eye on the sky when you’re deciding which departure time to choose.
Photos are available, but they’re optional. There are digital underwater photos you can purchase onboard, and they’re offered as professional shots of you and your family. If you’re traveling with someone who wants a memento but doesn’t love trying to capture underwater photos with a phone, this option can be worth it.
One practical tip: even if you buy photos, bring a plan for your personal device. Use the dry totes and keep expectations realistic. Underwater phone photography is hit-or-miss, and the park is best enjoyed by watching live.
Cost and value: is $49 a smart cruise-day purchase?
At $49 per person, this tour is priced for value, especially if you’re on a cruise and want something more meaningful than a basic shore walk. You’re paying for more than gear. You’re paying for:
- a guided experience in the water with the park team behind it
- the boat transfer that gets you quickly to Little Bay
- the sculpture field itself (300 structures, not just one stop photo-op)
- a cruise-friendly time window that helps you avoid the stress of running late
A key part of value is the structure of the day. You’re on the water for about two hours total, and there’s a clear rhythm: short boat ride, gear up, snorkel, back. That keeps the cost tied to real time in the water rather than long logistics.
The only “value question” is visibility. If the day turns cloudy, the sculptures and animals may be harder to see. Still, you’re snorkeling over a massive installation, so you’re not depending on one small moment. And even when people rate the experience as just good rather than perfect, they still point to the quality of the captain and guide.
There’s also an emotional value here. Being guided by the park’s own original creators can make the underwater scene feel more intentional, and it gives you something to talk about long after you’re back ashore.
Who should book, and who should skip
This tour fits best if you want an easy snorkeling experience with a clear payoff. If you enjoy sea life, love art, and want a guided explanation that goes beyond pointing at pretty shapes, you’ll probably have a great time.
It also fits well for cruise schedules because the meeting point is close to the terminal and the tour is designed to return you on time. If you’re choosing between several shore options, this one often feels like the best use of a limited day because it combines movement, scenery, and real time in the water.
Book with extra care if you are a non-swimmer. This tour is not recommended for non-swimmers. Even with safety floats, it’s still open-water snorkeling.
If you’re older or have mobility concerns, take heart. The tour has been praised for handling boarding and boat transfers with care. Ask questions before you go, wear the right footwear, and consider a calm pace once you’re in the water.
Best match checklist:
- Comfortable with snorkeling basics
- You want guided meaning behind what you see
- You’re traveling on a cruise and want a tight schedule
- You’re okay with the fact that cloudy weather can reduce visibility
Should you book Under SXM snorkel tour?
I’d book Under SXM if your priority is a guided snorkel experience with real structure. The combination of park creators as guides, a manageable two-hour time frame, included gear and safety floats, and the sheer number of sculptures makes it a strong value for St Maarten.
I’d hesitate if you’re set on maximum underwater visibility. Cloudy conditions can make the sculptures and fish harder to spot, so if you’re the kind of snorkeler who wants crystal-clear detail every time, you might feel disappointed on a gray day.
If you want a cruise-day win that feels authentic—artful, marine-focused, and run by the people who made it—this is an easy yes.
