BAJA CALIFORNIA, MEXICO
Baja California is the long desert peninsula running down the western coast of Mexico. It has become a hotspot for divers thanks to its unique position. On one side you have the Sea of Cortez, a very narrow but deep body of water littered with pinnacles and islets which funnel nutrient-rich water into the shallows, and on the other you have the huge Pacific Ocean with its mass of marine life. Marine mammals like sea lions, dolphins, killer whales, sperm and other whale species - including the largest creature on the planet, the blue whale - can be found in the waters off Baja California, as can hammerhead sharks, manta rays and whalesharks. One of the most-popular spots for diving is La Paz, which benefits from having three islands - Cerralvo, Espiritu Santo and San Jose - lying offshore which are a magnet for marine life and can produce some exciting diving experiences.
