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.

Most visitors to Playa Paraiso stay at one of the five huge Iberostar-branded resorts in town. Judging from the TripAdvisor reviews, everyone from honeymooners to families with kids can have a blast at the properties’ beaches and pools. Two excellent golf courses are also located in town.

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. Choose a beach with soft white sand for relaxing, or snorkel off a rockier vista. A destination for both adventure and romance, Cozumel has a year-round Caribbean climate, untrammeled jungle and abundant nightlife.

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.

Lively nightclubs pulsing with Caribbean beats drive the nightlife scene of Cabarate, a breathtaking beach town. Not even the stubbornly two-left-footed can keep their toes from tapping when the sun goes down on Cabarete, which brims with culture and energy. Beachfront bars cum discotheques are the perfect spot to shake what your Mami gave you.

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.

Vines, wines and the people who love them are central to the economy of Napa Valley. Other treats for the taste buds are in store, too, in the form of local olive oils, tomatoes, cheeses and mustard. The other senses are catered for with a vibrant visual arts scene. Hire a car or book a taxi or limousine to travel safely between sights. The Napa Valley Wine Train offers an unusual way to experience the views and vintages. A relaxing array of spas and mud baths and the Old Faithful geyser are attractions in Calistoga.

Portimao is a sailor’s delight, thanks to its calm waters and beautiful conditions. Plenty of elite international competitions happen here, but you don’t have to be a professional to set sail. Cruising the coast on the double-masted Santa Bernarda pirate ship is a family favorite. On dry land, you can wander the lovely Alvor boardwalk, enjoy a succulent seafood meal or zip around the go-kart track at the Autódromo Internacional do Algarve.
