Join other advanced certified divers on an incredible 'sea mountain' adventure in Baja's Gulf of California. Set out from Los Cabos to explore the depths of the Sea of Cortez—one of the planet's most biodiverse bodies of water—and Gordo Banks, a towering mountain that exists entirely below the sea's surface. This extreme formation is home to plenty of pelagic sea creatures, including sea snakes, marlin and tuna. It's also a favorite spot among hammerhead sharks. Enjoy ample time scuba diving and a leisurely lunch before returning to your hotel.
