St Maarten snorkeling tours
The Caribbean’s real treasures aren’t in the shops — they’re underwater.
St Maarten has two sides, two languages, and one ocean. Creole Rock, right here in Grand Case Bay, is one of the most vibrant reefs around the island. Tintamarre is where sea turtles graze in the seagrass like they own the place. And beneath Little Bay, 300 sculptures are slowly becoming a reef.
These are the snorkeling tours I’d actually look at first if I wanted to spend a real day in the water.
Quick answer

Best overall
Ten years at the top — not because of marketing, but because people come back from this tour and can’t stop talking about it. The speedboat takes you everywhere in one day: turtles at Tintamarre, the reef at Creole Rock, lunch on Pinel, and planes skimming your head at Maho. It’s for you if you want to see it all — both sides of the island, multiple snorkel spots, beaches and wildlife.
First-time visitors who want the full St Maarten water day.
Open bar, lunch, snorkel gear and several stops.

Best catamaran
Boomerang isn’t a tour, it’s a mood. A 54-foot catamaran that moves fast but feels like a floating living room — the crew cooks the BBQ while you’re underwater at Tintamarre looking for turtles, and you surface to a cocktail already waiting. Creole Rock, Pinel Island, Tintamarre: the holy trinity of snorkeling in St Maarten, all in one day.
Travelers who want the catamaran vibe without missing the best snorkel stops.
Open bar, BBQ lunch, paddleboards and snorkel gear.

Most local feel
This is the tour that shows you the whole island — not a highlight reel, the real thing. You leave Philipsburg with rum punch in hand and sail the coastline: Tintamarre first, then Creole Rock in Grand Case Bay, lunch onboard, and the afternoon unwinds slowly before the captain hands you a glass of champagne as you pull back into Great Bay. For people who want to understand St Maarten from the sea — both sides, all the way around.

Best for families and groups
Same crew, same catamaran, different rhythm. Where the full island tour covers more distance, this one slows down — more beach time, more water time, less pressure. Creole Rock, Tintamarre, open bar, lunch on board: everything you need, nothing you don’t. It’s for families, mixed groups, or anyone who’d rather float in turquoise water for an extra hour than tick off another landmark.
Families, mixed groups and relaxed travelers.
Open bar, lunch onboard and snorkel gear.

Most unique experience
Nobody sees this one coming. Beneath the surface of Little Bay, 300 sculptures are slowly becoming a reef — life-cast from real people of St Maarten, standing on the seafloor at about five meters deep, already covered in coral, already full of fish. This isn’t a classic boat tour. It’s an underwater museum, and the guides are the people who built it.
Travelers who want something different from the usual boat day.
Guided snorkel, gear and access to the sculpture park.
Decision guide
Choose Captain Bob. You see the most in one day — snorkeling, beaches and island highlights.
Choose Boomerang. More space, better food, open bar and a relaxed but still active day.
Choose Eagle’s full island sail. Creole Rock and Tintamarre make it feel more local.
Choose the Tropical Catamaran. More beach time and an easier rhythm.
Choose Under SXM. Shorter, different, and genuinely memorable.
Choose Captain Bob or Boomerang for strong Tintamarre access and good odds.
Where to snorkel
The one I always mention first. Right here in Grand Case Bay, a short boat ride from shore, with reef, fish and turtles passing through.
Uninhabited and protected — the sea turtles graze in the seagrass like they’ve never heard of tourists.
More beach than reef, but the rocky edges are worth exploring if you’re already there.
Where Under SXM lives now — calm water and 300 sculptures on the seafloor.
Before you go
Book early, especially between December and April. The good tours fill up fast and the best ones can sell out weeks ahead.
Morning is usually best. The water is calmer, the light is better, and you still have the afternoon free.
Bring reef-safe sunscreen, a waterproof phone case, a towel, and cash for tips. The crews on these tours usually earn it.
And if the captain tells you the turtles are there, trust him and get in the water. I have watched people hesitate on the boat while a sea turtle grazed a few meters below them. That is not a mistake you want to make.
