Bursting with color, culture, and variety, the Yucatan Peninsula and Riviera Maya bring together the best that Mexico has to offer: welcoming waters and white-sand beaches, colonial towns, jungle-shrouded cenotes, and UNESCO-listed archaeological sites. The region's best known—and most visited—Maya ruin is Chichen Itza, which features a massive step-pyramid known as El Castillo (The Castle), along with numerous, well-preserved carvings. Consider opting for a VIP-access tour to avoid the equally famous lines. Most international visitors fly into Cancun, famous for its luxury resorts and laid-back party vibes, or Merida, the region's largest city and cultural capital. In addition to nightlife, Cancun offers easy access to the entire Caribbean coast. Isla Mujeres is an ideal jumping-off point for snorkeling tours and at the right time of year, you can see whale sharks feeding nearby. The Maya ruins of Tulum are well worth a visit, as are Coba and Ek Balak. Check out Xel-ha or Xplor Adventure Park for high-energy, outdoor activities, such as ziplining over the rain forest canopy and cave rafting. The beach is never far away, and on the coral reefs around Cozumel and Isla Contoy, world-class snorkeling and scuba diving opportunities abound. Farther inland, Merida and colonial Valladolid offer myriad historical sites, pleasant streets lined with gardens and bright pastel buildings, artisans' shops, and a thriving restaurant scene. Be sure to sample some authentic Yucatecan dishes, like the distinctive black mole that takes hours to prepare, and tacos made with slow-roasted Yucatan turkey.
