Blue Water Diaries: Socorro Island
Article by

There comes a point in every diver's journey where the usual stops start to feel a bit repetitive. The reef dives are beautiful, the resort packages are comfortable, and the marine life is wonderful, but you want a little more...

If that sounds a bit like you, then Socorro Island might be exactly what you need. It’s not the kind of destination most divers hear about, but once you start looking, it's very hard to look away.
Why Socorro?
As a divemaster and marine ecologist, it's the kind of trip that ticks all my boxes: Socorro Island is part of the Revillagigedo Archipelago, a remote chain of volcanic islands roughly 250 miles off the southern tip of Baja California.
Many regard it as the “Galapagos of Mexico”, which is a comparison that makes geographical sense. But Socorro is something different.

“Socorro reminded me why I dive in the first place. It’s the kind of adventure that demands your focus, anchors you fully in the present, and rewards you with memories that stay with you long after you surface.”
Getting There
The journey to Socorro isn’t your typical dive trip. More often than not you jet into your dive location, sign up with a dive company, and maybe spend an hour on a speedboat to the local reef sites before heading back to your resort.

Socorro is an expedition. In fact, the only way to access the islands is by boarding one of the few liveaboards setting sail from Cabo San Lucas or San José del Cabo. By nightfall you’re already underway, and the crossing takes most of the next day and a half through the open Pacific Ocean. It’s a journey that certainly builds anticipation and sets the tone for what is to come.

Before You Go
Before any liveaboard, I like to arrive a few days before departure. It helps me settle in, acclimatise, and avoid the one scenario no diver wants to face: missing the boat.
Best you know, with Socorro’s long crossing, most operators simply won’t wait for late arrivals. But this is the real world and flights get delayed, luggage goes missing, and life just happens, so giving yourself a buffer isn’t just the smart thing to do; it’s essential.

Three nights in Cabo gave me plenty of time to shake off any travel fatigue, triple-check my gear, and enjoy a little pre-dive time with my feet in the sand.
I tacked on a few extra days before setting off to Socorro, purely because I couldn’t miss the chance to explore some of the area’s finest dive sites. Baja diving is so good it deserves far more than a passing mention. In fact, it warrants a trip all of its own. More on that soon…

To get a little taste of what was to come, I booked a few half-day dive packages that took me to local dive sites that mirrored the conditions I would be experiencing at Socorro. This gave me the chance to dial in my buoyancy, camera settings, and mentally prepare for what was to come.
For those who want a little extra time but would prefer to stay on land, Cabo Pulmo is worth a visit. It’s home to a UNESCO World Heritage marine park that's famous for its coral reefs, regular bull shark sightings, and massive schools of bigeye jacks.

Where to stay: Los Cabos will spoil you for choice, but if you’re looking for a little relaxation and luxury before heading offshore, I’d book into either the Waldorf Astoria Los Cabos Pedregal or the Four Seasons Resort Los Cabos.
Cinematic Arrivals
My first thought when I saw San Benedicto was “wow”. Its raw, volcanic landscapes are otherworldly. Almost like a place that the world had yet to catch up on.
Revillagigedo itself feels like a step back into Jurassic times. Apart from a small naval base, it’s just a vast, uninterrupted ocean with volcanic cliffs and pinnacles rising out of deep blue water.

However, Socorro is far from desolate. The dramatic seamounts draw creatures from all around, with pelagic life travelling enormous distances to collect below the surface. And you could feel it even before getting in: this was going to be something special.
Diving Socorro
Revillagigedo isn't your usual reef dive: it’s not passive diving, and adverse conditions should be expected.
However, choosing to dive in December proved to be an excellent choice; we had exceptional conditions with water temperatures sitting between 75 and 80 degrees Fahrenheit throughout our trip and consistently great visibility.
If you know me, you also know that I am always cold. Despite my concerns, a 5mm wetsuit kept me perfectly toasty, while many of my fellow divers were entirely comfortable in 3mm. Being the dry season, we had almost no rain, very calm seas and plenty of sun to bask in post-dive.

Negative entries are the norm, and you have to descend fairly quickly to avoid strong surface currents before settling along volcanic ridges at around 18 to 30 metres.
Once you’re below the surface, things are quite hard to articulate. But I’ll do my best.
Manta rays don’t just cruise past. They approach you from the deep, hover directly above you, exposing their bellies to your bubbles before gliding on by. They hold eye contact and, with a flip of their cephalic lobes, acknowledge you in a way that makes you feel like it’s a genuine exchange between two curious creatures inhabiting the same memorable moment.
There’s almost no way to capture, with words or photography, the quality of these encounters.
The Sites
What makes this liveaboard so special are the dive sites. Just when you think you can’t top one experience, another comes along.
El Boiler delivered the first: eight or more mantas within a single dive, with hammerheads and silvertips slipping quietly around your periphery.

Then, El Canyon brought a special surprise: multiple tiger shark sightings alongside the expected cleaning behaviour. Tiger sharks aren’t common in Socorro, so this felt like a genuinely humbling gift.
The vertical and exposed Roca Partida was next. And it's quite simply unlike any dive site I’ve seen. Stacks of whitetip sharks swimming along the current or resting on balconies, dolphins spiralling overhead, and a negative entry landing me face-to-face with a manta. If you’re one of the many lucky divers, a whale shark may join you on your safety stop.

And then, just when you don’t think anything could top the previous dive, Roca O'Neill came along and became a personal standout. It’s a site that’s less frequently visited, but the layers of topography and colour are so alive with both mantas and hammerheads.
“Quite simply, the finest pelagic diving of a life spent underwater.”

Life Onboard
Choosing who you do a liveaboard with can turn a good experience into an unforgettable one. While I might be a little biased, choosing one operated by a local Baja family was immediately noticeable.
The crew genuinely felt like a family that has only grown closer over the years, with the kind of knowledge that only decades of experience can produce. It felt like a privilege to be welcomed in for a week rather than being treated as a tourist just passing through.
Our cabins were comfortable, with everything you might need. We dined in true Mexican style: with generous, delicious meals that encouraged conversation. The dive guides rotated daily, bringing different styles and perspectives to each briefing and ensuring each day and dive felt new and exciting.
In remote diving, incidents can and do happen. Midway through the trip, one of the guests presented with mild decompression symptoms. The crew’s response was immediate, calm, and textbook. It was the moment that cemented trust entirely and validated the choice of dive company.

After it all
If you’re feeling inspired to dive Socorro or another multi-day liveaboard, here’s a very personal life hack.
While it’s technically possible to head straight to the airport, with no-fly times not a hindrance, I wouldn’t. Your body has been through something significant, not to mention your mind and emotions. It deserves time.
“After ten nights in the Pacific, arriving back in Cabo felt like surfacing twice. The world needed a moment to come back into focus.”

My personal preference is to always plan a short post-dive stay. Two nights is fine; three or four is a lot better. Give yourself time to decompress, reflect, and celebrate the ending to an extraordinary experience.

I made San José del Cabo my base: it’s a walkable town with amazing food, a fun art district and the kind of pace that suited the reflective mood I was in. However, depending on timing and seasons, Cabo San Lucas is a great choice too.

Where to stay: After a week and a half of wetsuit living, rewarding yourself with a little luxury is always recommended. For a post-dive stay, try the Montage Los Cabos, Esperanza Resort Auberge Collection, or One&Only Palmilla.
Is Socorro Right for You?
Diving Socorro is not for everyone. You’ll need at least an advanced open water certification, ideally an excess of 50 logged dives, peak buoyancy control, and genuine comfort diving at depth and in potentially tricky currents.

For those with the experience, preparation and ambition, Socorro gives something very few dive destinations can: a marine ecosystem that remains relatively untouched, wildlife encounters that feel genuinely wild, and an overriding sense of privilege that comes from knowing what you are witnessing is real, rare, and carefully protected.
“If you’re ready to dive somewhere that changes the way you think about the ocean, and perhaps a few other things, Socorro is not simply a destination; it's a must.”
If this trip, or any other diving experience, has been quietly building in the back of your mind, we would love to help you achieve a memorable moment.
