Mexico
Mexico is bordered by oceans, the Pacific Ocean in the west and the Gulf of Mexico on the east. There are few better places on earth to explore underwater life than Mexico's lagoons and coastal waters. It's difficult to imagine just how rich in natural beauty these waters are until you get under the surface. For pros, diving in Mexico is paradise and for beginners there are loads of oppurtunities for diving and snorekeling as well.
Scuba diving in Mexico is as varied as it gets. Steep walls and drift dives give way to a second dive on shallow scenic reefs. Eagle rays, turtles, nurse sharks and even whalesharks can all be found on the reef, amid schools of smaller reef inhabitants. Out in the Pacific hundreds of Great White Sharks gather each year near Guadalupe Island. This is probably the best location in the world for cage diving with these magnificent sharks.
Jacques Cousteau famously called the Sea of Cortez the aquarium of the world. Honouring its name, the wide variety of marine life there has drawn researchers, and those who simply want to marvel, from all over the world.
