The Jewels of Mexican Diving

Yucatán Peninsula: Cenotes and the Caribbean

The Riviera Maya is famous for its cenotes, freshwater underwater cave systems. They offer a surreal, almost mystical experience.

• Dos Ojos, El Pit, Chac Mool: Stunning formations, amazing light shows.
• Cozumel: Renowned for its vibrant coral reefs and strong currents that allow for drift diving. Turtles, rays, and reef fish are common.
• Playa del Carmen: A starting point for bull shark diving (November-March) and access to the cenotes.

Baja California Sur: The World's Aquarium

The Sea of Cortez, dubbed "the world's aquarium" by Jacques Cousteau, is a treasure trove of marine biodiversity.

• Cabo Pulmo: A protected marine park and a conservation success story. Home to huge schools of fish, bull sharks, turtles, and rays. You can book a Pack 6 Dives in Cabo Pulmo here!
• La Paz: Swim with playful sea lions at Los Islotes islet. Whale shark sightings (October-April).
• Socorro (Revillagigedo): A remote archipelago some 400 km southwest of Cabo San Lucas, a UNESCO World Heritage Site that can only be reached by liveaboard after more than a day at sea. There you dive with giant oceanic mantas that approach divers, hammerhead and silky sharks and, in winter, the song of humpback whales. It is open-ocean diving with currents: a destination for experienced divers.
