With its inimitable mix of Mayan ruins, sophisticated beach clubs, and world-class snorkeling opportunities, it's easy to see why Cozumel is one of Mexico’s top destinations. Immensely popular with cruise ships, Cozumel Island (Isla Cozumel) caters to short-stay visitors with a variety of shore excursions. Chichen Itza, a UNESCO World Heritage Site, and the archaeological ruins at Tulum are doable on day trips, while shorter cruise excursions invite you to drive an ATV to the cenotes of Jade Caverns; explore Chankanaab Park (Parque Chankanaab) in a submarine; or sail at sunset near Playa Palancar, home to the biologically rich Palancar Reef. Outdoor adventurers can choose from horseback riding, scuba diving, dune buggy driving (which is a big hit with families), and more. All-inclusive day passes to Mr. Sancho’s Beach Club and Playa Mia Grand Beach offer access to luxurious facilities and the sublime beaches of the Caribbean. A private Jeep excursion lets you design your own itinerary, which can include anything from archaeological sites and national parks to shopping, snorkeling, and tequila tasting. What’s more, with Cancun, Tulum, and Playa del Carmen just a short boat ride away, the island of Cozumel is an ideal base for exploring the rest of the Yucatan and the Riviera Maya.
