Socorro Islands



Socorro Islands in a Nutshell


Diving the Socorro Islands is a wide-angle adventure filled with giant manta and shark encounters, schooling fish, and other large pelagic marine life.


Intro to Socorro


The Socorro Islands are a group of 4 islands in the Pacific known as the Revillagigedo Archipelago. Socorro and Roca Partida are the most popular for diving, accompanied by San Benedicto and Clarión. The islands lie 240 miles (386km) southwest of Cabo San Lucas in Baja, Mexico, and are often called Mexico's "little galapagos" due to the their unique ecosystem and attraction of large pelagic animals. Searching for large pelagics leave divers with a choice between the Socorro, Galapagos, Cocos and Malpelo.  Socorro is the closest destination for those in the U.S.

Because the Socorro Islands are volcanic and rise out of the open ocean, the only scuba diving options are liveaboards.


Typical Socorro Dive


We recommend Socorro for experienced divers due to the exposed nature of the diving. The islands often see choppy seas and strong currents (which attract the rich pelagic life). The diving is correspondingly rugged, with rocky structure and some huge walls. Liveaboards will typically run 3 to 4 dives per day, diving the best sites at Socorro Island, Roca Partida and San Benedicto.


Socorro Marine Life & Photography Subjects


Socorro is known for its manta cleaning stations, where underwater photographers can often spend many dives with the gentle flying giants. They're regularly found when the water is warmer in the late spring. When the water cools during winter months (December - March), divers are treated to humpback whale sightings. Galapagos, silky, oceanic white tip and hammerhead sharks are common at Socorro, as well as dolphins, whale sharks (best in November) and schools of pelagic fish like jacks and barracuda. Divers often see large gamefish like tuna, wahoo and marlin, something few other destinations can offer. Those interested in shooting photos of some smaller creatures will find eels, octopi, nudibranchs and more.


Another "signature experience" at Socorro swimming with a group of bottlenose dolphins that often visits divers and typically makes several close passes.

Best Time To Dive The Socorro, Water Temps And Visibility


November - May is the best time to dive Socorro, and the liveaboards' itineraries correspond. Water temps range from 21-23C/70-74f during the winter and 24-28C/76-82f during late fall and spring. Usually a 5mm wetsuit with optional hooded vest works well at Socorro. Note that dive gloves are not permitted at Socorro by law. Visibility varies depending on the dive site, season, currents and other conditions. Roca Partida often has the best vis, reaching over 100 feet. There are sometimes reports of lower visibility in November/December (when whale sharks are found feeding on plankton).


Getting There


Divers fly into Los Cabos International Airport (SJD). Once through immigration, you'll meet a shuttle provided by your liveaboard to its departure point at either San Jose Del Cabo (15 mins) or Cabo San Lucas (40 mins). Most boats take about 24 hours to reach Socorro from either city.


Non-Diving Activites


Cabo San Lucas, and to a lesser degree San Jose Del Cabo, offer a range of non-diving activitites, including golf, fishing, village visits and various other options. Once you're at sea, however, topside activities are limited to standard liveaboard entertainment: catching up with fellow divers, editing photos, reading, etc. There is not much else to do there!

If you are interested on diving in Socorro you better be an advanced and prepared diver. We are talking about a group of island lost in the middle of the ocean, where you often find strong currents, blue water and deep diving. Also you have to sail for 26 hours to arrive to Socorro from Los Cabos. So, it´s a long journey and sometimes a rough one! All this to say that Socorro isn't for everybody, but in return you will do the best dives of your life!!! You will get tired of seeing dolphins, huge mantas, humpback whales (sometimes even underwater), yellowfin tunas, and 6 different species of sharks: white tips, silver tips, silkies, galapagos, tigers, and my favorite ones: the hammerheads. If you are lucky, like I was, you get to see big schools of them. Imagine watching almost 300 hammerheads passing quietly by your side, it´s a lifetime experience!!


The best time of the year to visit is during march and april, but if you are looking for whales sharks the best time is october, november. It´s up to you but in any case you will have close and intimate encounters during the 20 or so dives you will do during your 6 days trip.

Socorro is not a place for novice diver. The currents are strong, and even on calm days, there is a lot of surge (which is actually fun to ride in after awhile). None of that was unexpected -- after all, we were diving in the middle of the Pacific without any extensive reefs, or large islands to provide sheltered water.

The marine varies by season (we did not see whale sharks, for example, because they do not show up typically in January -- again no surprise), but is focused on large pelagic creatures. Socorro is all about wide-angle photography. We dove at 3 sites, (Canyon, Boiler, Roca Partida), all of which were very similar in the types of creatures you see. There is a surprising amount of interesting smaller creatures lurking in the rocks (I followed around a very sweet octopus for awhile) at the dive sites, but sadly they just tend to get ignored by divers in awe of the big stuff -- dolphins, sharks (hammerhead, silky, reef), and playful manta rays that seem to love swimming through the bubbles of divers. The experience of playing with the giant Pacific Manta rays, over and over again really made the trip worthwhile.

The dolphins were surprisingly shy (I know other divers have different experiences), but they did show up on 2 early morning dives at Canyon. Later on, we headed out in the panga boats, chasing humpback whales (there were 4 hanging out near the boat). We got close to one whale, but he dove immediately upon our approach. However, we did get to snorkel with a playful pod of dolphins, (and some curious sharks that made us a bit nervous), and got some nice video

Fine, really fine pelagic quarry diving and in our backyard (from NW US that is)! Our last several trips involved tortuous amounts of time in airplanes and ports but not so Socorro and yet the payoff is up there on the "best" scale. This November in the Revillagigedo islands, we made the CLOSE acquaintance of at least 4 whale sharks including a calf, saw white tips stacked like cord wood, Galapagos, Silvertip, and Silky shark cruised within 20 feet. Hammerheads, as they tend to, stayed on the blue edge. We have seen more than a few mantas elsewhere but these were there to entertain, coming in multiples and staying for the length of the dive. Octopus, turtles,humongous lobster, morays in most nooks, we had absolutely no shortage of sightings. Topside all there was time for was excellent eating and welcome beds before time to get deep again. Currents added some spice but not excessive danger to the experience. Visibility was affected by the storm crossing our path but was 75 ft at worst. Water temp was 74-80 degrees, we wore 5mm's to keep warm on successive dives. Our crossings a bit rough but hey, this is the Pacific and the dolphins were there for diversion. If you have dived enough to gain respect for open water and essentially bottomless sites, Socorro is for you!

Diving the Isla Revillagigedo has always been on my bucked list. I was finally able to cross it off in early December 2013. A short flight from LAX brought us to Cabo San Lucas. We overnighted in Cabo, and the next afternoon boarded theboat for the 22 hour ride to the islands. Our first stop was Isla San Benedicto. The boilers had a few manta rays circling us. Our next stop was Roca Pardita. A rock in the middle of the ocean, known for lots of pelagic fish cruising by. But not when we were there. I did see a group of hammerhead sharks deep. The pile of white tip sharks in the crevices was worth the ride. Then off to Isla Soccoro. Cabo Pearce had dolphin, turtles, schooling fish, lobsters and manta rays. Finally back to San Benedicto, and The Canyon. Dolphins and more mantas. Our final destination was The Boilers once more. And, more mantas.

This trip was basically Manta Madness. We had up to 7 flying carpets on one dive. I was told to make lots of noise. Apparently mantas like that sort of thing. I tested it. A manta would come by, I sang and screamed, it circled and circled. Same manta would swim by later in the dive. I was mute. It slowly glided by. Even later in the dive, said same manta approached, I sang and screamed (some say it's the same). Said manta circled and circled. I was perplexed why are the mantas approaching us bubble breathers? We don't offer food, nor cleaning. We aren't even allow to touch them. I think they're just as perplexed at the insane bubble breathers. A behavior I thought interesting, they would unwind their cephalic lobes in my face, and wind them back up. I wasn't sure what was proper reply was, so I just sang and screamed. Also, a manta with no tail, would come straight at me (and others), shoot straight up. Then like a stalled biplane, drop back down. Recover and do it again. I had always thought that mammals only did things for FUN. I was wrong, these guys may have had more fun the we had.

I would consider this a fairly advanced sort of trip. Long bumpy boat ride (bring your meds). Help is a long way away. Large ocean swells, and currents. But the reward is great big animal encounters. I tend to do macro videography. I even brought my macro stuff along. Save luggage weight, leave the macro stuff at home. His is a wide angle adventure.
