Imagine waking up to the gentle sway of the sea, the Caribbean sun rising above turquoise waters, and the promise of a perfect day ahead. That’s what a day on a boat in Saint-Martin feels like — effortless, exotic, and unforgettable. Whether you’re sailing on a catamaran, chartering a private yacht, or hopping aboard a boat tour, this island offers endless possibilities.
If you’re wondering what to do in Saint-Martin during a day on a boat, here’s a full guide packed with local tips and must-see spots. Let’s dive in.
Start your day at Simpson Bay Lagoon
Kick off your nautical adventure from Simpson Bay, the heart of boating life on the Dutch side of the island. This protected lagoon is one of the largest in the Caribbean and home to some of the island’s best marinas. Grab a coffee at a dockside café, meet your captain, and prepare to set sail.
Pro tip: Most charters leave from Simpson Bay or Marina Fort Louis on the French side. Both are convenient and close to major attractions.

Sail along the coast to Baie Longue
Once you’re out on the water, cruise along the western coastline to Baie Longue, a dreamy, crescent-shaped beach near Belmond La Samanna. It’s secluded, serene, and perfect for a swim. The contrast between the white sand and the deep blue sea is unreal.
Drop anchor, jump in, and enjoy your first swim of the day — with no crowds, just sea turtles and pelicans for company.
Snorkel at Creole Rock
Next stop? Creole Rock, just off the coast of Grand Case. This protected marine reserve is a snorkeler’s paradise. The water is calm and crystal clear, with tons of colorful fish darting around the reef. Bring your mask and fins — or let your charter provide them.
Even if you’re not a strong swimmer, floating above the reef with a noodle is pure bliss.
Lunch stop in Grand Case
After all that swimming, you’re ready for lunch — and you’re in luck. Grand Case is one of the best culinary destinations in the Caribbean. Many boat charters will dock here for a couple of hours, giving you time to explore the charming waterfront village.
Choose between a beachside lolo for grilled lobster and ribs, or sit down at a French bistro for something more refined. Either way, you’ll eat well. Very well.
Island hop to Tintamarre
In the afternoon, head to Tintamarre Island, a small uninhabited slice of paradise just a short sail from Saint-Martin. The beach here feels completely wild — soft sand, zero infrastructure, and often more iguanas than people.
Some tours include a mud bath here (yes, a natural one!) that leaves your skin feeling surprisingly soft. Or just lay on the beach and soak up the silence.
Champagne and sunset at Pinel Island
On your way back, swing by Pinel Island, a postcard-perfect sandbar with shallow water and lounge vibes. Order a glass of rosé or a cocktail at the beach bar, float lazily in the shallows, and let the afternoon sun kiss your skin.
Many charters like to end the day here with drinks and a last swim before heading back.
Back to the dock – but the day isn’t over
As your boat glides back into the marina, the sun sets behind the hills, painting the sky in hues of orange and lavender. It’s tempting to call it a night, but if you’re not ready to end the magic, Saint-Martin’s nightlife awaits — from beach bars in Simpson Bay to rooftop cocktails in Marigot.
Tips for a perfect boat day in Saint-Martin
- Book in advance: Private charters and popular boat tours sell out quickly, especially in high season.
- Pack light but smart: Sunscreen, sunglasses, a hat, towel, swimsuit, and something dry to wear later.
- Don’t skip the reef shoes: Some beaches and snorkeling spots have rocky entries.
- Bring cash: Especially useful for drinks and food on small islands like Pinel.
- Stay hydrated: It’s easy to forget when you’re sipping rosé in the sun.
