Socorro, San Benedicto, Roca Partida and Clarion are four volcanic islands that make up the Revillagigedo Islands, some 250 nautical miles south of Cabo San Lucas. These incredible islands are renowned for their marine megafauna encounters and are on many diver wish lists. Read on for Aggressor Adventures’ ultimate guide to Socorro diving.
Top 5 dive sites in Socorro
- Roca Partida
Roca Partida is only a small, guano-covered rocky islet poking out of the Pacific Ocean – it measures just 130 feet in height, and some 100 metres in length – and is so compact that divers can circumnavigate the entire site a couple of times on one dive. However, what it lacks in size it makes up for in content. The vertical walls attract hordes of pelagics, from various shark species (silky, gray, hammerhead, whale) to dolphins, manta rays and even humpback whales. It is an unmissable highlight of every Socorro diving adventure!
- The Boiler (El Boiler)
The Boiler is one of the most-famous dive sites at San Benedicto Island and it is considered the premier spot for interacting with giant manta rays in the whole of the Socorro chain, as they congregate here to be cleaned by clarion angelfish. It is a large pinnacle that rises up from the depths to within 20ft of the surface. Like Roca Partida, the site can be circled several times on a single dive. As well as the friendly mantas, which seem to bask in the exhaled bubbles of the divers, you can also expect to see dolphins, sharks and whales.
- The Canyon (El Canyon)
San Benedicto’s other ‘must-dive’ site is The Canyon. While mantas sometimes put in an appearance, this site is all about sharks – expect to see silkies, Galapagos sharks and hammerheads. The latter usually in vast schools numbering hundreds of individual animals. As with all sites in Socorro, you never know what else might turn up out of the blue when you go Socorro diving.
- Cabo Pearce
Cabo Pearce is a top dive site on Socorro Island. It is effectively a long, thin finger of rock that stretches out off the east coast of the island and extends into the current. Massive schools of hammerheads characterise Cabo Pearce, although you can also encounter silky sharks and manta rays. The best bet is to drop down and take shelter from the sometimes-strong current among the rocks and wait to see what comes cruising by.
- O’Neal Rock (Roca O’Neal)
O’Neal Rock is also known as Hammerhead Central, which might give you an inkling as to what you might see at this Socorro Island dive site. As well as the seemingly ever-present hammerheads, you can also see Galapagos sharks, grays and silkies, but if you can tear yourself away from the pelagics, on the plateau at 33ft-39ft, you can find smaller critters such as lobster, and there is also a photogenic cavern.
Top tips for your Socorro diving trip
Socorro is known as Mexico’s ‘Little Galapagos’ due to their remote location and plethora of pelagic animals that you can encounter, although it is often compared with the likes of Cocos Island and Malpelo as well.
Getting to Socorro
Socorro is by far the easiest to get to from the USA, with the Aggressor departing from San Jose del Cabo, which has its own airport. It can take 24 hours to travel to this magnificent area, so make sure you take some good books, catch some ZZZs so you are ready for the diving to come, and catch up with your fellow adventurers on board. Plus, there will be plenty of movies to while away the hours in the main salon, or in the comfort of your own stateroom.
Safety is paramount, especially when you are diving way offshore as at the Socorro Islands. All divers must carry a whistle and an inflatable safety sausage or DSMB at all times, and will also be provided with individual Lifeline GPS/radio beacons.
When to go Socorro diving
You will always have amazing dives at Socorro regardless of when you go, but the Socorro Aggressor aims to hit some of the optimum months, operating from mid-November to the end of June (the vessel moves to Guadalupe Island from August to early November).
Experience needed for Socorro diving
Diving at the Socorro Islands is recommended for experienced divers, due to the often choppy seas, strong currents and abyssal walls. You need to be confident in your buoyancy and happy dealing with surge, swell and currents.
