The Socorro Islands (Revillagigedo Archipelago) are Mexico's answer to the Galapagos — a remote volcanic chain where giant Pacific mantas, some with 20-foot wingspans, approach divers with remarkable curiosity. During winter months, humpback whales fill the water with song and occasionally make close passes. The 24-hour liveaboard crossing from Cabo San Lucas is the price of admission to one of the Pacific's most thrilling big-animal destinations.
