“The Socorro Islands” Mexico’s Revillagigedos Archipelago Text and photos by Barb Roy Located 386km (250 miles) southwest of the tip of Baja California and over 720km (446 miles) west of Manzanillo, the Revillagigedos are one of three Mexican island groups in the Pacific Ocean. All four islands that make up the Revillagigedos Archipelago are remote, volcanic in origin and offer some of the most unpredictable, wild diving in the world. Isla Socorro is the largest of the Revillagigedos islands. Over the years, visitors have adopted the name—“The Socorro Islands”—when referring to this group. Depending on the time of year and which island you visit, a diver might encounter the graceful splendor of a humpback whale and her calf or be able to swim alongside a gargantuan whale shark. These won- drous creatures are all in addition to the archipelago’s regu- lar residents: giant Pacific mantas, hammerhead sharks, yel- lowfin tuna, sea turtles, over five other species of sharks and countless other large pelagics who utilize this offshore area. 28 X-RAY MAG : 18 : 2007 EDITORIAL FEATURES TRAVEL NEWS EQUIPMENT BOOKS SCIENCE & ECOLOGY EDUCATION PROFILES PORTFOLIO CLASSIFIED travel Socorro Islands CLOCKWISE FROM FAR LEFT: Brilliant coloured gargonians grace the reef at Socorro Island; Slipper lobster; Octopus; Neon coloured reef fish.
