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. 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.

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.

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.

Akumal means "Place of the Turtle" in the Mayan language, and if you snorkel here, you just might see one swimming alongside you. (Don’t touch it, though. That’s prohibited by law.) You’ll definitely see coral and beautiful fish in the clear, sparkling waters. This tourist-friendly little town is about an hour south of Cancun—but it seems light-years away.

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.

Tulum is relaxation and romance with an ancient angle. Guests can enjoy modern takes on traditional Mayan massage and spa treatments, or sunbathe on gorgeous Yucatan beaches within site of well-preserved ancient ruins. A rare mix of beach, archeology and village, Tulum is a romantic getaway like no other.

In friendly Great Exuma, you'll want to be up early so you don't miss a moment outdoors. From fishing and sailing to snorkeling and windsurfing, there's almost too much to do.

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.

Everything about Santa Monica sizzles, from hundreds of funky shops and restaurants to more than three miles of white sandy beach, to the multitude of celebrities zipping into the local airport and out on Montana Avenue. The subject of popular songs, movies and television shows ("Baywatch" was one of many filmed here), the city has a vibe like no other. Hollywood haute couture meets surfer chic meets hippie casual, and somehow it all works. A word of advice: ditch the car and walk everywhere. Santa Monica is small and prides itself on being pedestrian- and environmentally friendly. You won't need wheels at the auto-free Third Street Promenade, a stroller's paradise known for its multitude of cinemas, restaurants and street performers. Or at the famous and historic Santa Monica Pier, home to tempting smells from fast-food stalls and the solar-powered, nine-storey high Ferris wheel that has long been a symbol of the city. If your feet start to fail, hop on the electrically powered Tide Shuttle, a bus service that runs along the beach offering great views plus a ride to the artsy Bergamot Station and the Santa Monica Museum of Art, or your next spirited Santa Monica destination.

The Cape Verdean island of Sal is all about the beach, baby. White sand stretches along glassy turquoise waters—perfect for a lazy day of sunning or some heart-pumping watersports. Snorkelers and divers will find plenty of tropical fish, turtles, and dolphins to look at. On dry land, kids (and grownups!) will marvel at the Terra Boa mirage, an optical illusion that conjures a peaceful-looking lake in the middle of a large, flat plain.
