When divers think about rebreathers, the conversation often turns to depth, decompression, and technical diving.
But in the Galápagos, that somewhat misses the point.
You don’t need a rebreather because the dives are not particularly deep. You want to be diving one because Galápagos is a place where time underwater matters.
This is one of the world’s great wildlife diving destinations. At Darwin and Wolf Islands, huge schools of scalloped hammerheads can appear out of the blue. Whale sharks cruise past. Eagle rays, Galápagos sharks, and turtles share the water, while elsewhere in the archipelago you might encounter sea lions, marine iguanas, penguins, flightless cormorants, and mola mola.
And when you’re surrounded by that much wildlife, the last thing you want to do is look at your pressure gauge and realize it’s time to return to the surface.
It’s not about going deeper. It’s about staying longer.
Dirty Dozen’s Galápagos CCR-Specific itinerary is specifically designed with rebreather divers in mind, with two dives per day of up to 120 minutes.
Think about that for a moment.
Rather than squeezing four conventional dives into a day, the philosophy is to make the dives you do count.
You descend. You settle in. You wait.
And in Galápagos, waiting can be extraordinarily rewarding.
Become part of the scenery
There is another reason CCR and wildlife diving work so well together: bubbles, or rather the lack of them.
We all know that researchers and scientific divers remark on how useful rebreathers can be when working around wildlife. It makes intuitive sense. Instead of announcing your presence every few seconds with a noisy rush of expanding exhaust gas, on CCR you are relatively silent.
That doesn’t mean a hammerhead will automatically swim up and pose for your camera because you’re on a rebreather. Wildlife is wildlife, and there are never guarantees.
But it does remove one significant source of noise and disturbance which makes a huge difference with so much marine life around.
Find your position. Get comfortable. Stay quiet.
And let Galápagos come to you.
The hammerhead experience
This is perhaps where the difference becomes most obvious.
Imagine settling onto the rocks at Darwin or Wolf. There’s current running, so you’re tucked into position rather than swimming around unnecessarily.
Then the first hammerhead appears.
Then another.
And another.
The temptation is to swim towards them. But instead, you stay where you are.
There is no stream of exhaust bubbles roaring towards the surface every time you breathe. Your breathing doesn’t suddenly change the soundscape around you.
Eventually, you can begin to feel less like a visitor chasing an encounter and more like an observer sitting quietly inside it.
For photographers and videographers, that opportunity can be particularly valuable. More time doesn’t simply mean more photographs. It gives you time to stop shooting, watch the animals, understand how they’re moving and anticipate what might happen next.
Sometimes the best photograph comes after you’ve been sitting still for 20 minutes.
A different kind of technical diving
None of this means CCR makes Galápagos easy.
Quite the opposite.
Galápagos can involve substantial currents, changing visibility, and demanding entries and exits. A diver needs to be comfortable with both the environment and their rebreather.
There’s also an interesting operational challenge unique to CCR.
Sourcing Sofnolime, O2, and a booster in such a remote location is no easy task, and National Park rules mandate that CCR divers must be guided by a qualified park guide, also on CCR.
This is where Dirty Dozen Expeditions steps in. Working with local experts, they make rebreather diving in the Galapagos not only possible, but hassle-free.
Their Galápagos itinerary offers a CCR package of unlimited Sofnolime and O2 fills, unit-specific onboard tanks, and a rigged bailout, as well as knowledgeable CCR guides and access to their team’s expedition planning experience.
Their itinerary includes warm-up dives before reaching the more demanding sites, appropriate bailout requirements and specific CCR operating practices developed from years of running rebreather expeditions in the world’s premier CCR destinations.
Dirty Dozen x Shearwater: Galápagos 2028
And that brings us to 2028.
From 16–23 August 2028, Dirty Dozen Expeditions is heading back to Galápagos aboard the M/V Galaxy Diver III for a special expedition, and Shearwater Research are onboard! The trip offers 16 divers the opportunity to experience Galápagos alongside two industry giants.
Having Shearwater specialists on an expedition like this adds another dimension to the week. When you’re not underwater watching hammerheads, whale sharks, and sea lions, you’re sharing a boat with people who understand the technology we rely upon to make these dives possible.
That’s very much the Dirty Dozen philosophy: the expedition isn’t only about where you’re diving. It’s about who you’re diving with and what you can learn along the way.
The itinerary takes advantage of some of the archipelago’s most celebrated diving, including Darwin Island, Wolf Island, Roca Redonda, Punta Vicente Roca and Cabo Douglas. Dirty Dozen’s current schedule allows for two dives per day of up to two hours each, conditions and individual dive plans permitting.
So, why take a rebreather to Galápagos?
Not because you want to go deeper.
Because you don’t want the dive to end.
Because when you’ve finally got a wall of hammerheads moving through the blue, you want time to sit there and watch.
Because when a sea lion decides you’re interesting, you don’t want your gas supply determining when the encounter finishes.
Because being quieter around wildlife can allow you to become an observer rather than constantly announcing your presence.
And because Galápagos isn’t really a destination where the objective should be to collect dives.
It’s a destination where you want to make every dive count.
A rebreather gives you something incredibly valuable in a place like this: time.
And in Galápagos, you never quite know what might swim past next.
The Dirty Dozen Expeditions x Shearwater Research Galápagos expedition runs 16–23 August 2028 aboard M/V Galaxy Diver III, with both CCR and open-circuit diving available.
