There are a few Mayan archaeological sites that can easily be visited on day tours from Cancun, and luckily, tours typically include round-trip hotel transfers and lunch. Chichén Itzá is the big one—it’s a UNESCO World Heritage site and was one of the largest of the Mayan civilization’s great cities. Meanwhile, the Tulum Archaeological Zone is known for its perch with views of the turquoise sea, while Cobá boasts the tallest pyramid in the Yucatan.

Just outside the Hotel Zone, Dolphin Beach (Playa Delfines) is a quiet stretch of white sand that feels a world away from the crowded beaches, pool parties, high-rise hotels, and rowdy nightclubs that more often define Cancun. The beach’s elevated position at one of the city’s highest points offers sweeping views of Cancun and the Caribbean Sea, and, often, the pods of dolphins for which it is named, making it the picture-perfect setting for a relaxed beach day.

Some of the Yucatan’s most distinctive natural features, cenotes, are sinkholes that have created natural underground swimming pools. Historically used by the Maya as a water source and the occasional setting for ceremonies, today they are popular with tourists and locals alike who swim in their cool, fresh waters. Many tours combine time at a cenote with a visit to a Mayan archaeological site such as Chichén Itzá or Cobá and on a hot day, there’s nothing better than taking a refreshing dip.

Created by the British sculptor and environmentalist, Jason deCaires Taylor, the Cancun Underwater Museum (also known as Museo Subacuático de Arte, or MUSA) makes for a diving or snorkeling experience like no other. The underwater museum displays more than 500 life-size sculptures on the ocean floor with the goal of promoting ocean conservation. You can explore the submerged statues by a snorkeling or diving tour from Cancun. If you’d rather stay dry, consider a glass-bottom boat tour, instead.

The enormous nature reserve of Nichupté is a system of lagoons that covers 7,400 acres (3,000 hectares) in the heart of Cancun. With crystal-clear water and lush mangrove forests, Nichupté’s seven fresh and saltwater lagoons are places of scenic beauty and playgrounds for an array of water-based adventures, from kayaking to jet-skiing, to watching wildlife such as crocodiles, turtles, and more than 100 bird species.

The small island of Isla Mujeres is just 8 miles (13 kilometers) off the coast of Cancun and offers a quiet and relaxing escape. Catamaran sailing tours and ferries offer transportation from Cancun. Some sailing tours are party-themed, and the alcohol flows freely, while others offer a more relaxing experience suitable for families. Once there, enjoy diving, snorkeling around the colorful reefs, glass-bottom boat tours, and fishing charters.

There are a number of markets around Cancun that sell traditional Mexican crafts such as ceramics, textiles, home decor, and jewelry. Mercado 28 covers an entire city block in the heart of town. While visiting can be an overwhelming experience, it is a great place to pick up some souvenirs before having a bite to eat in the central food court. Another option is Mercado Ki Huic, one of the city’s longest-running markets located on busy Avenida Tulum, just outside the Hotel Zone.

The biggest fish in the sea, whale sharks, gather in the warm Caribbean waters off of Cancun to feed and mate in the summer, typically from mid-June to early September. Many tours depart from Riviera Maya and provide the opportunity to snorkel in these same waters and view the majestic creatures from a safe and respectful distance—be sure to choose a tour operator with a strong environmental track record. You’ll also have the opportunity to spot dolphins, manta rays, and turtles.

South of Cancun, near Playa del Carmen, a collection of family-friendly parks including Xcaret, Xel-Ha, and Xplor offer a multitude of activities including ziplining, water rides, swimming in underground rivers, and cultural experiences such as meeting with local artisans and watching pre-Hispanic cultural demonstrations. A day at one of these parks makes for a fun alternative to another day on the beach and offers a different take on the Riviera Maya that is suitable for all ages.

Cancun’s nightlife scene is the stuff spring break dreams are made of, and for those who want to live it up after the sun goes down, there are dozens of bars and clubs in town to check out. Coco Bongo, Señor Frogs, and the massive, 6,000-capacity City Nightclub are three of the most legendary, but different clubs are the place to be on different nights, so consider a nightclub tour to hit the best parties at the right time with a ready-made social group.
