Best Dive Sites In Socorro

Roca Partida

Roca Partida, meaning ‘split rock’, is often considered the best dive site in the Revilagigedos archipelago. The dramatic topside scenery combined with incredible underwater encounters makes Roca Partida an essential part of the Socorro scuba diving experience.

Around 64 miles (40km) from Socorro island, this small pinnacle rises from the seafloor at 50m (164ft) all the way up to the surface. This dive site is quite literally a magnet for all the big marine life.

Marlin, oceanic manta rays, mackerel, dolphins, and humpback whales are regularly sited here.

Plus you’ll find several shark species including Galapagos sharks, oceanic whitetips, scalloped hammerheads, and whale sharks.

Although the site itself is quite small, the pelagic encounters are so prolific that this incredible site will have you dying to drop in again and again. Every dive at Roca Partida offers a different, yet equally mesmerizing experience. This site is not to be missed when scuba diving in Socorro.

San Benedicto

San Benedicto is the third largest of the Socorro Islands and famous worldwide for its unbeatable manta ray encounters.

And we’re not just talking a quick glance at a passing manta ray or two. Or even a manta ray swirling around you a couple of times. But a succession of extended and intimate interactions with several gigantic Pacific manta rays.

The Boiler is the very best dive site in the Revillagigedo archipelago for experiencing this manta magic. Named after the swirling surface conditions, this magnificent pinnacle rises from 165ft (50m) to within 20ft (7m) of the surface to create a popular cleaning station full of hungry angelfish.

The ginormous oceanic manta rays that gather here seem to welcome scuba divers, making close eye contact as they swim by to enjoy your bubbles. Other marine heavyweights also gather at this cleaning station including tiger and whale sharks. And if you’re really lucky the humpback whales will make an appearance. Even if you don’t see them, their song provides the perfect soundtrack to an unforgettable dive.

Roca O’Neal – Socorro Island

Often referred to as Hammerhead Central, Roca O’Neal is the best dive site in Socorro for spotting scalloped hammerhead sharks.

Gazing out from this rocky slope you’ll quickly lose count as a vast school of hammerheads weaves its way into the current. There’s also a good chance of spotting gray reef, silky and Galapagos sharks here.

Scuba Diving In Socorro

Scuba diving in Socorro is an adrenaline-fueled adventure filled with Pacific’s largest residents. Come prepared for exhilarating drift dives along steep drop-offs, exposed pinnacles, and deep seamounts.

Because Socorro can only be accessed by a liveaboard, all of the diving here is from a boat. 

You’ll gear up on the main dive deck before jumping into a small tender which will drop you at the perfect spot based on the conditions.

The water temperatures in Socorro range from 70 to 82°F (21 to 28°C) with December to April being the coldest months. So if you’re planning to enjoy 4 dives a day, make sure you pack a thick wetsuit and hood!

The visibility in Socorro is surprisingly good compared to most scuba diving destinations in the Pacific. Depending on the season, plankton bloom, and site, visibility will range from 50 to 98 ft (12 to 30m).

Due to its remote and open ocean location, Socorro is exposed to the full force of the powerful Pacific currents.

While this brings a lot of the pelagic action, it also means that the diving conditions here can be challenging and unpredictable. Surface conditions can also be quite choppy.

Therefore, scuba diving in Socorro is only recommended for advanced divers with experience in strong currents.

Socorro is home to a huge number of oceanic manta rays, with many individuals reaching over 6m in wingspan. Unlike anywhere else on earth, these gentle giants approach and often accompany divers.

Best Time To Dive In Socorro

The best time for scuba diving in Socorro is between November and May. These months offer the best sea conditions and the highest chance of big marine life encounters. Plus the weather is usually sunny with only the occasional rain shower.

Although oceanic manta rays are present throughout the year in Socorro, the majority of shark species are only spotted during the winter months. Plus as Socorro’s waters begin to cool, the plankton starts to bloom. This attracts hundreds of migratory whale sharks to the area, especially during the full moon.

The best time to see humpback whales in Socorro is between January and April when thousands of them come to breed and calve in the area.

From June to October, the sea conditions are too rough for liveaboards to get to Socorro. And the water temperatures rise meaning that most of the pelagic fish head off to find cooler spots.

Honestly, all of the dive sites in Socorro are seriously spectacular. But here are a few of the all-time favorites to whet your appetite.

How To Get To Socorro

You can only access the Socorro islands on a liveaboard. Socorro liveaboards will usually depart from San Jose del Cabo or Cabo San Lucas at the southern tip of the Baja Peninsula in Mexico.

The crossing takes around 24 hours and can be very rough. So make sure you bring seasickness tablets. It’s a long journey to reach these far-flung islands, but the pay-off is well worth the effort.

A Few Final Things You Should Know About Scuba Diving In The Socorro Islands

Due to its rich and unique biodiversity, the Revillagigedo archipelago is classed as a UNESCO world heritage site. Biosphere regulations prohibit divers from using glovesknives, or lights. However, lights for underwater cameras are allowed.

Keep in mind that the best time to dive here is also the coldest. Bring plenty of exposure protection, both for during and between dives. Especially if you want to get as many dives in as possible.

Socorro island is a naval base and occasionally closed to scuba divers due to military operations.

And lastly, scuba diving in Socorro is not suitable for beginners. Due to its open ocean location, the dive sites are exposed to strong currents and rough surface conditions so scuba diving in Socorro can be very challenging.

If you’re new to scuba diving it’s recommended that you gain some experience diving in currents before heading out to Socorro.

Socorro is a destination that only a handful of intrepid divers make it to. But it is most certainly worth the trip.

There really is nowhere else on the planet that offers such breathtaking underwater moments as scuba diving in Socorro.

And if you’re ready to embark on the underwater adventure of a lifetime, then it’s time to check out the best liveaboards in Socorro.
