Airelles Takes Over Rosewood Le Guanahani in St. Barth: How to Book the Newest Maison

St. Barth has long been the Caribbean's most exclusive island, and this winter it gains the address to match. On November 1, 2026, Airelles, fresh from Versailles, Courchevel, and its Venetian debut, reopens the legendary Le Guanahani, formerly the Rosewood Le Guanahani and the largest, most storied resort on the island, as its newest Maison. It is the first time the French collection has crossed the Atlantic, and it arrives just in time for the holidays. Here is what to know, and how to plan a stay.

Airelles takes over the former Rosewood Le Guanahani and opens on November 1, 2026. This first winter is a careful evolution rather than a wholesale reinvention: the essence that made the resort beloved stays intact, the private peninsula within a protected nature reserve, the secluded white-sand beaches, the intimate Caribbean atmosphere, and the warm, familiar teams who have always run it. What changes, gradually and then more extensively over time, is what Airelles does best: new dining, reimagined family experiences, a new beach club, and the collection's signature generosity, in a setting that already ranks among the finest in the Caribbean.

St. Barth is the Caribbean's most exclusive island. Airelles is one of Europe's most exclusive collections. For the first time, they meet.

The resort occupies a rare position on St. Barth: a private peninsula at Grand Cul-de-Sac, on the island's northeast coast, with two beaches of its own, a calm, reef-protected lagoon on one side and the open sea on the other. It sits within a protected marine nature reserve, which is why the water is so clear and the setting so quiet. On an island defined by small, intimate hotels, its scale and grounds have always set it apart, and give Airelles the room for gardens, pools, and genuine family space that are hallmarks of the collection.

The Maison keeps what works and adds the touches Airelles is known for. Guests this season will find a new generation of dining, reimagined family spaces, a new beach club, and a level of hospitality, and generosity, that is the collection's signature.

Accommodation is being organised into a new collection of rooms and suites. Among the future room options are the Ocean Bay Room and Ocean Bay Pool Room, the Beach Room set steps from the sand, the Ocean Cove Junior Suite, and, for the widest stretch of sea and a private plunge pool, the Ocean View Suite and Ocean View Pool Suite. Categories, aspect, and configuration vary, and part of what we do is match the right room to the trip, whether that is a couple's escape or a family taking a cluster of rooms together.

The opening lands at the busiest, most coveted moment of the St. Barth calendar. The island's peak runs from American Thanksgiving through Christmas and into New Year, when the harbour at Gustavia fills with yachts and the best tables, villas, and rooms are spoken for months in advance. For its first winter, Airelles St. Barth will be among the most requested addresses on the island, and the earliest stays begin on November 1.

The dates to plan around are the marquee holiday weeks, Thanksgiving, Christmas, and New Year, along with the quieter, and often lovelier, stretches of January, February, and March. Because holiday demand outstrips supply on St. Barth every single year, these weeks are the first to go. As a Fora-affiliated advisory, we submit your request directly to the Maison and add VIP recognition and benefits at no additional cost; the earlier we inquire on your behalf, the better the room category and the dates we can pursue. If those weeks are on your calendar, now is the time to start.

Stays also come with twice-daily housekeeping and the quiet, attentive service the peninsula has always been known for. As a preferred partner, we can layer recognition on top, at the same published rate: a resort credit to use across dining and the spa, a category upgrade when one is available, and early check-in or late check-out when the day allows.
