Baja California

Topside, Baja's cactus-studded mountains, and earthy landscapes are a stark contrast to the lush realm thrumming with life below the surface. Fin-to-fin encounters with megafauna are what makes diving in Baja California special, with most of the action taking place in the Sea of Cortez. This strip of water nicknamed "the world's aquarium" by Jacques Cousteau - is accessed via a pair of islands an hour offshore. It's a treat - but not uncommon - to spot orcas, dolphins, or whales from the boat before you even reach the dive site.

Besides, super friendly Californian sea lions are the highlight of most dives. Pups love to play with divers and pose for the camera so it's a fun excuse to sharpen your underwater photography skills.

Location: Baja California, Mexico.
