Santa Rosa Wall: Sit back and enjoy the ride at one of Cozumel’s marquee dive sites. A strong current whisks you past a long wall, mottled with stony overhangs and gaping caves, and home to massive sea fans, translucent sponges, and tropical fish of every size and color.

Palancar: With five sections spread over three miles, this massive dive site has something for everyone. Snorkelers can check out Palancar Shallows, while divers can explore the winding ravines and natural arches of Palancar Horseshoe. No matter where you go, you’ll enjoy rich coral and vibrant sealife.

San Gervasio: Smack dab in the middle of the island, Cozumel’s best and biggest Maya ruin is thought to be dedicated to Ixchel, the goddess of fertility; in ancient times, it attracted women from all over the Yucatán seeking her favor.

Playa Chen Río: Heavy surf makes most of Cozumel’s east side unswimmable, except here, where a rocky arm forms a calm natural pool. Come midweek to have it all to yourself, or on a Sunday to convivir (literally, “share life”) with local families.

Faro Celarain Eco Park: Snorkel the colorful ocean reef, or stay above water on a catamaran tour of a crocodile-filled lagoon at this scenic nature reserve. Here at the island’s southern tip there’s also a small museum, ancient Maya lighthouse, and plenty of room to relax on the sand.
