Socorro is the largest of the four volcanic Revillagigedo Islands, a UNESCO World Heritage Site and Mexico's largest no-take marine reserve, lying roughly 460 km south-southwest of Cabo San Lucas. Reachable only by liveaboard, it is world-famous for curious giant oceanic manta rays that seek out divers, friendly bottlenose dolphins, and schooling sharks in open Pacific water.

Description
The Revillagigedo Archipelago—Socorro, San Benedicto, Roca Partida, and remote Clarion—rises as the exposed peaks of submarine volcanoes in the open eastern Pacific, about 460 km south-southwest of Cabo San Lucas at the tip of Baja California. Inscribed as a UNESCO World Heritage Site in 2016 and declared a national park and ~150,000 km² fully protected (no-take) marine reserve in 2017, it is often called 'Mexico's Galapagos' for its concentration of large marine animals and its endemic landbirds. There are no resorts and no permitted shore access for tourists: every dive is run from a liveaboard out of San José del Cabo / Cabo San Lucas, with a crossing of roughly 24 hours each way. Diving is current-swept, often deep and exposed, and best suited to experienced divers—most operators ask for an Advanced certification and around 50 logged dives. The signature encounter is the giant oceanic manta ray (Mobula birostris), which gathers at volcanic cleaning stations such as The Boiler and Cabo Pearce and frequently approaches divers. Resident bottlenose dolphins, schooling scalloped hammerheads, silvertip and Galapagos sharks, whitetip reef sharks 'stacked like firewood' at Roca Partida, plus seasonal whale sharks and wintering humpback whales round out one of the planet's premier big-animal dive destinations.
Highlights
What makes this dive worth the trip.
Revillagigedo was inscribed as a UNESCO World Heritage Site in July 2016 and in November 2017 was declared a national park surrounded by North America's largest fully protected marine reserve—about 150,000 km² (636,685 ha core) where fishing, mining, and tourism development are banned.
There is no land access or resort diving: the archipelago is reached only by liveaboard, with a crossing of roughly 24 hours from San José del Cabo / Cabo San Lucas, so trips typically run 8–10 days and most operators require Advanced certification and around 50 logged dives.
Socorro's giant oceanic manta rays (Mobula birostris) are famous for actively seeking out divers, hovering over groups to enjoy the bubbles—The Boiler off San Benedicto and Cabo Pearce off Socorro are among the world's best oceanic-manta cleaning stations, where clarion angelfish clean the rays.

Dive sites
5 signature sites at this destination.
Roca Partida
A tiny twin-peaked rock just 100 m long and a few metres wide—the exposed summit of a huge submarine seamount in open ocean about 100 km west of Socorro Island. Sheer vertical walls plunge well past recreational limits, and the surrounding blue water is a 'gas station in the middle of the Pacific' for pelagics. Whitetip reef sharks pack into recesses on the rock ('cuddle puddles' of up to 15 animals), while silvertip and Galapagos sharks, schooling jacks, yellowfin tuna, scalloped hammerheads, giant mantas, and seasonal whale sharks patrol the open sides. Strong easterly currents mean divers usually enter at the sheltered middle/east face.

Cabo Pearce
A long, finger-like ridge of lava rock that juts out from the east coast of Socorro Island, formed when the island was an active volcano. Strong north–south currents accelerate across the ridge and feed one of the best oceanic-manta cleaning stations in the world, with giant mantas and resident bottlenose dolphins that interact freely with divers. Schooling scalloped hammerheads patrol the open water off the point and silky sharks are common; humpback whales are sometimes heard here in winter.

El Boiler (The Boiler)
A roughly oval, football-field-sized guyot (flat-topped seamount) off the northwest coast of San Benedicto that rises from about 35–45 m to within a few metres of the surface—named for the boiling-water look of swell breaking over its shallow crown. It is the archipelago's premier giant-oceanic-manta cleaning station, where clarion angelfish service the rays and the mantas, used to divers, routinely initiate close encounters. Silky sharks circle the boat and dive groups, with Galapagos and scalloped hammerheads in the blue and dolphins passing through.

Punta Tosca
A series of colourful lava fingers off the southwest of Socorro Island, regarded as one of the most scenic corners of the archipelago. Famously friendly bottlenose dolphins frequent the site and often stay to play with divers, and oceanic mantas, silky and reef sharks, and moray eels are seen along the ridges. Tiger sharks and whales are occasional visitors.

El Cañón (The Canyon)
A site on the southern side of San Benedicto built around shark cleaning stations and a sandy channel, best dived early in the morning when shark activity peaks. Silvertip, Galapagos, and silky sharks come in to be cleaned, occasional tiger sharks pass through, and the open water above the canyon can fill with massive schools of scalloped hammerheads. Tuna, jacks, and dolphins add to the action; giant mantas are also seen here.
