The 8 Best Adults-Only All-Inclusive Resorts in St. Lucia

·Extraordinary Piton and Caribbean Sea views from open-wall sanctuaries.

One of the Caribbean's true originals, adults-only 'sanctuaries' with no fourth wall and a private infinity pool framing the Pitons. There are no TVs and barely a reason to leave the room, though the organic chocolate lab and included diving tempt you out. Architectural, romantic, unforgettable. Best December through May.

·Exceptional Piton views

Ladera sits on a ridge above Soufriere with the Pitons filling the view. Its 37 suites are open on the fourth side, three walls and no glass, with a private plunge pool in every one. That design is the whole reason to come and the thing to understand before booking, because open walls mean birds, insects and weather come in with the view. Guests who knew that adore it. It is adults-only.

·Exceptional private-suite setup

Serenity at Coconut Bay is a couples-only enclave of plunge-pool suites beside St. Lucia's international airport, for a short luxury trip. It is about 5 minutes from Hewanorra, on the flat southern tip of the island, and shares its beach and its grounds with the much larger Coconut Bay resort next door. The Pitons are a day trip up the coast; the suite, the pool on its terrace and the butler are what you are buying.

·Excellent snorkeling beach

·Strong adults-only romantic positioning.

·Excellent calm-beach setting

Sandals Grande St. Lucian is a couples-only all-inclusive on the causeway to Pigeon Island, for couples who want St. Lucia's calmest beach. The included activities are the most on the island. It sits at Rodney Bay in the north, about 90 minutes from the international airport, with twelve restaurants, seven bars, five pools and overwater bungalows on the lagoon. The transfer is long and included; the beach at the end of it is the reason the resort exists.

·Highly romantic low-rise beach setting.

·10 restaurants and 8 bars included.

Sandals Regency La Toc is a couples-only resort on a hilly 220-acre estate near Castries, for couples who will trade flat ground for the view. It is about 75 minutes from Hewanorra, with ten restaurants, eight bars, three pools and a half-mile crescent beach below the hill. The hills are the appeal and the drawback at once: the views are why people book it, and the walking is real.
