THE BEST All Inclusive Resorts for Adults Only in Castries

There's more than one way to enjoy the spa experience in St. Lucia. One is to book a treatment at any of the luxury spas or resorts on the island. The other is to visit Sulphur Springs, inside the bowl of an extinct volcano, where you're welcome to try a volcanic mud bath or the 31°C/88°F Roman bath.

This Gallic toehold in the Caribbean exudes a distinctly French air, enticingly spiced up by West Indian warmth. Local culture and cuisine combine both influences. The stylish isle is dominated by Mount Pelée, which destroyed the city of St Pierre in 1902. Black sand beaches and rainforests are found in the north, with yet more beautiful sands to the south. Sights include La Pagerie, birthplace of Napoleon's Empress Joséphine, and Diamond Rock, a 600-foot pinnacle that was once registered as a British warship.

There are 32 islands and cays that make up St. Vincent and the Grenadines (SVG). Nine are inhabited, including the mainland St. Vincent and the Grenadines islands: Young Island, Bequia, Mustique, Canouan, Union Island, Mayreau, Petit St Vincent and Palm Island. The stunning Tobago Cays National Marine Park is also located within SVG. This multi-island Caribbean nation offers a combination of rainforest eco-adventures, scuba diving, classic Caribbean powder-white sand beaches, luxury accommodation and yachting or sailing adventures.

Among the best golf destinations in the world, Punta Cana is the very picture of leisure. Several of the courses have been designed by professional golfers, making for the perfect sort of kicked-back challenge that you want on a golfing vacation. The beaches here are simply perfect: calm, warm waters that gently lap at stretches of fine white sand. Thrill yourself with a zip-line adventure, clap along with traditional Dominican music at a cultural performance, or explore the magical lagoons of the Indigenous Eyes Ecological Park.

The Dominican Republic lies in the same waters as Cuba and Puerto Rico, taking up the eastern two-thirds of the island it shares with Haiti. Offering a lush interior with a mix of caves, Victorian gingerbread houses and the lore of pirates, plus 900 miles of coastline along its brim, island highlights include riding a cable car up Mount Isabel de Torres and basking on stunning Saona Island. Oh, and did we mention the D.R. is family-friendly, has just about perfect weather and is affordable?

Jamaica is a melting pot of African, Asian, European and Middle Eastern cultures. You'll experience this diversity in its strong crafts tradition, performing arts and distinctive dining options, like ackee and saltfish with roast breadfruit. Take your holiday to new heights at famed cliff jumping spot, Negril Cliffs. Jamaica offers long beaches, protected coves, rugged mountains, waterfalls, caves and sunshine and chances to play in the surf, ride horses and swim with dolphins. Jump in!

U.S. citizens still need to jump through a few hoops to visit Cuba, but as visitors from around the world know, this island offers some amazing opportunities for cultural exchange. Havana is a mix of old-world architecture and of-the-moment culture. Head out of the capital city to the small town of Trinidad to see more Spanish colonial architecture. It’s a UNESCO World Heritage Site and a fantastic home base for a visit to the Valley of the Sugar Mills, a pocket of land that formerly served as the centre of Cuba’s sugar industry.

Cayo Coco, an island just north of mainland Cuba, has some of the world’s most gorgeous beaches—think superfine white sand and shallow, clear water. It’s popular with European travelers seeking a sunny escape at one of the island’s beach-side resorts. Snorkeling and diving are fantastic.

There are no two identical Bahamas holidays. With options as diverse as its 700 islands, the Bahamas may seem schizophrenic: is it a family destination, a place for lovers to sneak away, a gambling mecca, a cruise-afficianado’s chief port of call or a shopper’s world market? The answer is, yes. It’s that, too.

Cuba's top beach destination sits on a 13-mile-long peninsula with powder soft sands lapped by waters of the Kawama Channel. Resort hotels teem along the shore that U.S. celebrities and gangsters, including Capone, discovered in the 1920s. Clubs and bars provide mojitos and merriment, after long days baking on the beach, golfing, diving or deep sea fishing. Rent a scooter or hop aboard an open-air tourist train or bus to see more of this stunning spot. Caves, keys and virgin forest add to the area's allure.

It’s not just for spring-breakers. Cancun, with its golden beaches and perfect climate, is the premiere coastal destination in Mexico. And while there is certainly a 365-day party available for college students, resorts cater well to families and to those seeking solitude. This Yucatan paradise is also the gateway to the ruins of Tulum and Chichén Itzá.

Dozens of nightclubs, hundreds of restaurants and some of Mexico's best beaches await you in Puerto Vallarta. The original colonial town still shines through an endless selection of shopping, art galleries, water and land activities, and hotels. Walk the malecon (boardwalk) and just try to take it all in.

Mexico's fastest-growing resort area offers miles of empty desert and deserted beaches. Laid-back nightlife and old-fashioned fun in the sun is the Cabos' lure. Only certain beaches are safe for swimming, however, including Lovers' Beach and the more tempestuous and aptly named Divorce Beach. Whale-watching, hang-gliding, snorkelling, antique-hunting, golf and fishing, Loreto's historic mission, and sport fishing and dining in capital La Paz are other attractions. SuburBaja buses travel the coast.
