Socorro Island history and information
Socorro Island is the largest of the four islands of this volcanic archipelago in the Pacific Ocean.
The island was discovered by the Spanish explorer Hernando de Grijalva in 1533. The Islands are owned by Mexico and Socorro Island has been home to a Mexican Naval Station since 1957.
As a result of the proximity of the Mexican military, Socorro Island is occasionally closed to divers due to military operations.
A large percentage of the original vegetation of the Revillagigedo Islands has been destroyed over the last 50 years. This is as a result of the introduction of domestic sheep. This was done on the island in the 1960’s and 70’s, and has contributed to the loss of at least 1% of the native vegetation.
Feral cats have also unfortunately contributed to the reduction of the native bird populations on the Islands of Revillagigedo. But it is also the naval officers and their families, who are responsible for the gradual destruction of the vegetation too.
The islands have received federal protection since 1994, yet an adequate management program is needed to help protect the endemic flora and fauna.
Revillagigedos Archipelago diving and the dive sites
Socorro Island diving
Socorro Island Cabo Pearce dive site
The Socorro Island Cabo Pearce dive site is indicated on the surface by a thin finger of rock. This rock stretches out from the east coast of the island.
Cabo Pearce is a reef that extends out into the prevailing current. This area is always frequented by dolphins and they are often on the surface to greet the liveaboard boat on arrival.
It’s not often that dolphins hang around with scuba divers in most places where they are seen. However, around Socorro Island they seem to like to interact with scuba divers.
Quite often the dolphins are still there when you enter the water. They sometimes stay around for the whole dive.
So if you’ve also always wanted to scuba dive with dolphins, Socorro Island is also the place to head to.
At the Socorro dive site you’ll experience quite a strong currents. This means the only way to experience this dive site is to protect yourself from the strongest current in amongst the rocks.
You are likely to see scalloped hammerheads here, which is usually in a large school. You may also experience silky sharks as well as the Galapagos sharks.
If you are visiting in the winter months you may also catch a glimpse of a humpback whale too.
But of course the star of the show is the Socorro Island manta rays at Cabo Pearce.
Punta Tosca dive site Socorro Island
The Punta Tosca dive site near to Socorro Island is known for encounters with humpback whales at the right time of year. This is in addition to encounters with dolphins, plus the possible tiger shark.
San Benedicto island diving
The San Benedicto Island is the third largest in the Revillagigedos Archipelago group of islands.
It’s likely you’ll see similar large underwater animals that you experience at Socorro Island. But San Benedicto Island diving is renowned for the quality of manta ray encounters there.
If you are lucky, this will not just be a passing manta or two, but instead it will be prolonged and close-up interactions with several Giant Pacific Manta Rays.
At this dive site they come to be cleaned by Clarion angel fish.
This dive site is also visited by hammerhead sharks, whitetip sharks, silky sharks, the possible tiger shark, whale sharks if you’re lucky and the friendly dolphins too.
But then you may have a background compliment of whale song by the Humpback whales too. Which is almost guaranteed to send shivers down your spine.
One of the main features at the San Benedicto Island dive site is The Boiler. The Boiler is a larger pinnacle which rise up from the ocean bed at 50 metres deep (165 feet), to within 6-7 metres (20 feet) of the ocean surface.
This is a manta ray cleaning station, where the Clarion angel fish are keen to clean the visiting Pacific Ocean manta rays.
There can be few manta ray experiences in the world that rival this region, both in terms of the size of the manta rays and for the intimacy of the encounters.
On the surface around The Boiler you’ll see what looks like a boiling sea, as the currents swirl around the top of this pinnacle.
You don’t need to dive too deep at this dive site and certainly no more than 30 metres (100 feet). This is because most of the action is nearer to the surface.

In the video below, which was taken on The Boiler, San Benedicto Island, you’ll spot whitetip reef sharks, dolphins, a moray eel, hammerheads and of course manta ray closeups.
