There are lots of ways to see and experience the sea in Los Cabos: by air while parasailing; by land while riding horseback along the coast; and by boat while fishing. One of the more novel ways to experience the ocean, though, is via mini-sub. Never seen one? Visualize your own taxi-yellow underwater scooter, with a big bubble helmet attached.
Several outfitters in the area, including Cabo Tour Center and Oceanus, have mini-subs and lead guests on underwater excursions. Highlights of the warm-water cruise through the Sea of Cortéz include glimpses of exotic fish, manta rays, and sea turtles. No diving experience is needed.
