MEXICO

The Rosewood Mayakoba is a way-cool, brand-new luxury retreat in Mexico’s Riviera Maya opening this December. Situated on a mile-long white sand beach surrounded by a mangrove jungle just 30 minutes south of Cancun, Mayakoba is sure to be the wave of luxury resort future: high-end accommodations with a definitive “green” nod to the environment. Relax in luxury without carbon-emitting guilt in one of the modern, chic beachfront units made of indigenous materials, or be at one with nature in a lagoon suite that respects the local flora and fauna. Move throughout the property via waterways on boats called lanchas so as not to disturb the herons and manatee. Play on the championship Greg Norman golf course, swim in the spa’s natural crystal-clear sinkhole, scuba or snorkel at the world’s second largest coral reef, travel to nearby Mayan ruins, or explore the in-house tequila library. From $490 per night. 888-767-3966; www.rosewoodmayakoba.com.

TURKS AND CAICOS

The Turks and Caicos Islands are located just 575 miles southeast of Miami and have become just as hip. But with popularity comes development, construction, noise, and the very destruction of the island’s original allure. Amanresorts has managed to restore some serenity with the opening of Amanyara—appropriately meaning “peaceful place”—along the coast of Providenciales. With its secluded white sand beaches, rocky coves, and proximity to some of the best reef walls and dive sites in the world, Amanyara provides the perfect mix for beach and water-sports enthusiasts. Forty pavilions—nestled within vegetation, on the edge of ponds, or along the oceanfront—have an Asian feel, with large glass doors that open to the elements. There’s a tranquil reflecting pool, library to borrow reading materials, pool with endless views of the turquoise ocean, and bar with large lounging beds. You’re clearly here to unwind. Rates start at $1,000 per night. 866-941-8133; amanresorts.com.

ST. LUCIA

For another chic new resort, there’s Jade Mountain at Anse Chastanet, one of St. Lucia’s most luxurious offerings. Jade Mountain is an exclusive resort within a resort, with 24 infinity-edge pool sanctuaries that are virtual rooms built high into the mountainside that seem to float in space. Check in at Jade Mountain’s own private reception area and get ready for an experience of a lifetime. Each suite combines a living room, bedroom, bathroom, and infinity-edge pool in one large open area with 15-foot ceilings and the fourth wall missing entirely, providing some of the most phenomenal views of the Caribbean and the island’s Piton mountains. The entire resort is tech-free—no telephones, radios, or televisions—but each suite has a unique bell pull cord to summon room service and housekeeping 24 hours a day. And if you ever decide to retreat from your exclusive digs in the sky, you can visit the resort’s spa, take a dip in the Club’s large communal pool, or enjoy access to all of Anse Chastanet’s leisure and sports facilities, including two beaches. This place is chic, it’s swank, it’s exclusive, and it’s bound to create memories—along with views—you will never forget. Rates start at $1,150 per night. 800-223-1108; www.jademountainstlucia.com.

BARBADOS

ROOM WITH A VIEW: Above: Relaxation is on the horizon at Jade Mountain in St. Lucia. Whether on land or at sea, the service at Sandy Lane in Barbados aims to please.

Pack your Bermudas, your clubs, and a dinner jacket, and head to Sandy Lane in Barbados for some of the best the British West Indies has to offer. This ultra-traditional, ultra-luxe, and ultra-stuffy resort isn’t the grande dame of the Caribbean for nothing. Originally built in 1961, this coral-stone Palladian-style mansion has seen the likes of Jacqueline Kennedy, Mick Jagger, Princess Margaret, Elton John, and Luciano Pavarotti. And after a recent multimillion dollar overhaul and expansion, it’s equally at home with today’s celebrities, royals, and business elite—Tiger Woods even chose to get married here. Situated on a beautiful crescent-shaped beach with three golf courses, Sandy Lane offers plantation furnishings, wall-mounted wide-screen plasma televisions, packing and unpacking services, personal butlers, a 24-hour concierge, remote-control everything (even the drapes), two open-air dining rooms on the beach, Bentley airport transfers, and beachside service—including sunglass cleaning. The list of world-class amenities is as long as the guests are famous. Rooms start at $950 per night. 866-444-4080; www.sandylane.com.
