On the eastern side of the island, Grand Cul-de-Sac is unlike any other beach in St. Barths: a shallow lagoon enclosed by a reef that breaks the swell, where the water remains calm even when the Atlantic roars in the background. As a result, two groups of people coexist there in perfect harmony: kitesurfers taking advantage of the trade winds, and families whose children splash around in complete safety.

The Lagoon with Two Faces

When it comes to wind, the lagoon is one of the best kitesurfing spots in the Caribbean: calm waters, steady trade winds, and on-site schools for beginners and those looking to improve. The sight of the multicolored kites is part of the place’s charm, even when viewed from a lounge chair.

As for tranquility, the knee-deep water stretching for dozens of meters makes the lagoon the island’s best beach for young children—and a lovely place to leisurely snorkeling : The seagrass beds are home to turtles and rays, which can be observed by gently paddling along at a respectful distance.

Around the lagoon

The bay is home to a few waterfront hotels and restaurants, perfect for spending a full day there. Hikers can continue on to Petit Cul-de-Sac and the wild coastline of Toiny, one of the island’s most spectacular stretches of shore—the contrast between the peaceful lagoon and the Atlantic crashing just a few hundred meters away is worth the trip alone.

Incorporate it into your trip

From Grande Saline, it’s about a quarter of an hour by car: Grand Cul-de-Sac is perfect for a day trip—kitesurfing or swimming with the kids in the morning, lunch by the lagoon, and a visit to the Toiny coastline in the afternoon. Then head back in the lodge's garden at the end of the day, when Saline Beach is perfect for the last swimmers of the season. For families, it’s the perfect combination: the lagoon for the little ones’ safety, and the villa with a pool for the rest of the time.
