Just north of Cancun, this seaside resort community is a far cry from the spring-break crowd. Bordered on one side by the Mexican Caribbean and the other by a wetlands wildlife preserve, the vibe in Playa Mujeres is one of laid-back luxury in a natural, untouched landscape. Unlike many other such tranquil places, Playa Mujeres is not a pain to get to. It's an easy ride from Cancun airport.

Isla Mujeres offers a wide variety of tempting options for beach lovers, and is a relative bargain. Snorkel with tropical fish amid coral reefs, skim the blue waters by kayak or boat, or windsurf along the shores of soft, sandy beaches. On land, you can sunbathe, dine on seafood, dance to Latin rhythms, tour on a moped or belly up to the bar for fresh, delicious drinks.

Puerto Morelos, a peaceful village on the Mayan Riviera, is a place to experience the genuine Yucatan. Puerto Morelos makes an excellent base if you’re looking for someplace quieter than glitzy hotspots like Cancun and Playa del Carmen. Government eco-reserve designations protect the reef and mangroves—and the village itself—from development. Outdoor options range from thrilling jungle and diving adventures to serene bike rides or moped explorations.

Stretching from the fishing village of Puerto Morelos to the biosphere reserve of Sian Ka'an, the Mayan Riviera offers an unforgettable Caribbean coastline experience. Divers and snorkelers will be dazzled by the wrecks of Xcaret and the Puerto Morelos reef. Use a zip line to descend into the sacred subterranean caverns of LabnaHa Eco Park, where you can snorkel an underground river under a canopy of stalactites. The nearby Tulum Monkey Sanctuary will put you in a playful mood.

One of the top diving destinations in the world for its bright storybook coral reefs, the island of Cozumel is also home to a variety of natural beaches.

Puerto Aventuras mingles tropical beauty with the riches of the sea. Beaches are fantastic, with powdery, white sand, and there's excellent fishing as well. For a fun day, explore the eco-archaeological park Xcaret, or snorkel at Xel-ha, a natural inlet water park. The Mayan ruins at Tulum, only 25 minutes away, are another must-see.

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.

Jamaica is a melting pot of African, Asian, European and Middle Eastern cultures.

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!

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.

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?

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.

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.

Visit Aruba once and you'll instantly start planning your next visit. The island wins you over with gorgeous weather, serene beaches, exciting land and sea activities (ATVs in the outback, anyone?), and terrific nightlife, from restaurants to casinos and nightclubs.

You'll find crashing waves off Cabo's Pacific coast and sheltered, calm water on the Sea of Cortez.

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.
