Visiting Cancun for the First Time? Here's What to See and Do

The biggest fish in the sea, whale sharks gather in the Caribbean waters off Cancun in the summer, typically from mid-June to early September. Tours to swim with them are a splurge but worth it for the unparalleled experience of seeing the gentle giants up close in the wild.

A small island just 8 miles (13 kilometers) off the coast of Cancun, Isla Mujeres is a popular day-trip destination for all ages. Catamaran sailing tours and other cruises transport visitors to the island, often with a few hours on the water for snorkeling and swimming. Some tours are party-themed, while others offer a more relaxing experience suitable for families.

South of Cancun near Playa del Carmen, a collection of family-friendly parks offer the chance to see a different side of the Riviera Maya. Depending on your interests, choose from one of four aquatic, outdoor-adventure, jungle, and eco-archaeological parks—Xel-Ha, Rio Secreto, Xplor, or Xcaret. Activities such as ziplining, water rides, and swimming in underground rivers make for a fun alternative to another day on the beach, plus some parks are built around Maya ruins.

Cancun’s nightlife scene is the stuff spring-break dreams are made of, and for those interested, there are dozens of bars and clubs to check out. CoCo Bongo is one 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.

One of the Yucatán’s most distinctive features, cenotes are sinkholes that create natural underground swimming pools. Associated with sacred Maya ceremonies, today they are much-visited attractions where you can swim in cool, fresh waters. Many tours combine time at a cenote with a visit to a Maya archaeological site.
