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.

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.

Once a sleepy fishing village, Placencia has emerged as an increasingly popular eco-destination on the Caribbean. For those who enjoy outdoor adventure, the Stann Creek region offers a host of activities: hiking through mountainous rain forests, kayaking, deep sea fishing, diving and exploring Mayan ruins. The peninsula boasts 16 miles of tranquil beaches, with a lagoon to the west and the Caribbean to the east and lots of peace and quiet in the middle. Tour guides and dive centers offer a variety of excursions, with boat rides to the outer cayes an ongoing favorite. Also popular are guided land tours to Mayan Ruins or trekking the jungle trails of Cockscomb Basin Wildlife Sanctuary, where the first Jaguar Reserve in the world was established.
