Divers ask us the same thing: which boat, and why. The dive fleet isn't the naturalist fleet — different vessels, different rules, a certification floor most first-timers don't expect. Here's how the liveaboards we book actually compare, deck by deck.
Galapagos dive liveaboards are a separate fleet from the naturalist cruises, built for reaching Darwin and Wolf, where hammerhead schools and whale sharks gather. We currently book two liveaboards for Galapagos dive trips: Calipso Yacht and Galaxy Diver II. Most operators want Advanced Open Water certification, 30 to 50 logged dives, and current-diving experience. Water swings roughly 16 to 26°C across the season. Whale sharks run June through November, peaking July through October. Current departures and starting prices are in the table below.
There's no single best Galapagos liveaboard, and anyone who tells you otherwise hasn't matched a boat to a diver. The right pick depends on where your logged-dive count stands, whether Darwin and Wolf's big-animal density is the whole point of the trip or one part of a broader route, how much cabin comfort you want after cold-water diving days, and whether you're carrying a camera rig that needs its own bench space. What we can tell you upfront is the shape of the fleet itself: it's small and purpose-built, a distinct handful of vessels built for one crossing, not the 40-vessel naturalist fleet that works the central and western islands. If you're still weighing a liveaboard against the naturalist route, start with our Galapagos diving page. This page is for divers who've already decided a liveaboard is the way in.
A naturalist cruise gets you snorkeling with sea lions and marine iguanas across the central and western islands, and it never takes you to Darwin and Wolf. Those two volcanic outcrops sit well north of the main archipelago, inside the Galapagos Marine Reserve, and the only way in is a dedicated multi-day dive liveaboard built for the crossing and the conditions once you're there. If snorkeling the central islands on a naturalist cruise sounds like enough water time, our guide to the best months for snorkeling in the Galapagos walks through that comparison.
Picture the dive itself: you clip a reef hook into a crack in the rock, current pulling hard enough that letting go means a drift you didn't plan, and the water in front of you goes gray — not with poor visibility, but with hammerheads, dozens of them, moving as one shape along the wall. That's Darwin. It's why divers fly here specifically, and why the trip is built around advanced-diver conditions rather than a gentle introduction.
We hear the same misconception from first-time inquiries almost every season.
"People book a naturalist cruise, see the word snorkelling, and assume the diving comes with it. It does not. The naturalist boats never go to Darwin and Wolf — they are not built for the crossing and they do not have the permits. If those two rocks are the reason you are coming to the Galapagos, you need one of the two dive liveaboards, and there is no version of this where a cruise with some snorkelling gets you there."

The current and surge that make Darwin and Wolf spectacular are the same conditions that make this advanced diving, not something you ease into on day one. More on the certification floor below.
Here's the roster: we currently book two liveaboards for Galapagos dive trips, Calipso Yacht and Galaxy Diver II. That's a short list on purpose — Darwin and Wolf are a narrow, specialized run, not a destination every operator's boat is built for. The comparison below reflects what we can confirm publicly right now; the cells still open are ones we verify per sailing date rather than print once and let go stale.
| Vessel | Divers per trip | Cabins | Dives per day | Nitrox | Dive deck & camera stations | Itinerary | Certification floor | Price-from |
|---|---|---|---|---|---|---|---|---|
| Calipso Yacht | 16 divers | 10 (8 double/twin, 2 lower-deck singles) | 3 to 4 (17–19 per trip) | Optional; unlimited fills included free for certified nitrox divers | 52 m² stern deck, 3-level steel camera table with an air line, bi-level rinse tank for GoPros and SLR housings, dry charging bench | Thu–Thu from San Cristóbal. 3 full days at Darwin & Wolf, 10–12 dives north | Advanced Open Water; 30–50 logged dives by season and route, 100 recommended June–November | See the departures table below |
| Galaxy Diver II | 16 divers | 9 (all convertible twin/matrimonial) | 2 to 4 (19 planned) | Optional; unlimited fills included free for certified nitrox divers | Wide low stern platform, dedicated camera table with non-slip padding, separate camera rinse tanks, dry charging station | Wed–Wed from Baltra. 3 full days at Darwin & Wolf, 12 dives north | Advanced Open Water; 30–50 logged dives by season and route, 100 recommended June–November | See the departures table below |
Calipso Yacht is one of the two liveaboards we currently book for Galapagos dive itineraries. It runs 16 divers across 10 cabins with two dive guides, so the group splits eight and eight in the water, and does 3 to 4 dives a day for 17 to 19 across the week. The itinerary is Thursday to Thursday out of San Cristóbal, with three full days at Darwin and Wolf for 10 to 12 pelagic dives. Two things set it apart: the dive deck is a 52 m² stern platform with a three-level steel camera table plumbed with an air line and a bi-level rinse tank, so an action camera is not sharing a bin with an SLR housing; and it holds two dedicated single cabins on the lower deck. Reach out and we confirm the current setup for your dates before you book.
Galaxy Diver II is the second liveaboard in our current dive roster, operated under the Ecoventura brand. It also runs 16 divers with two guides, across 9 cabins that all convert between twin and matrimonial beds, and plans 19 dives over the week. The itinerary is Wednesday to Wednesday out of Baltra, and the northern allocation is the highest we book: three full days at Darwin and Wolf for a dedicated 12 dives, including La Ventana, El Derrumbe and Darwin's Arch. The stern platform is wide and low for tender boarding, with separate rinse tanks for cameras and for gear. Galaxy Diver II doesn't have a Galapagos Insiders vessel page yet, so we're not linking to one here.
"For a first Galapagos dive trip I lean toward Calipso, and the reason is the deck rather than the diving. Both boats give you the same three days up north. Calipso has the better camera handling — a proper three-level table with an air line and a rinse tank that will not crush a GoPro under an SLR housing — and two single cabins, which matters if you are coming alone. If the only thing you care about is dive count at Darwin and Wolf, then Galaxy Diver II gives you twelve up there and that is more than anything else we book."

Galapagos diving earns its advanced-diver reputation the hard way: strong current, surge at exposed sites, negative entries where you drop straight down off the panga instead of a slow descent, cold pockets from a thermocline that can hit without warning, and visibility that shifts with the current on the same dive. None of that is exaggerated for effect — it's the reason the certification floor exists.
What we and the operators we book require: Advanced Open Water certification or the equivalent, plus 30 to 50 logged dives, depending on the specific itinerary and which sites it includes. Prior experience diving in current matters as much as the number in your logbook — some of the more remote, demanding sites call for more dives logged, or a case-by-case look at your experience before we confirm the booking. We verify the exact floor for your chosen vessel and itinerary before you commit, rather than publish one number that's meant to cover every trip. If you're still working out whether your certification and dive count clear the bar, our guide on Galapagos liveaboard requirements goes deeper.
On these two, the picture is the same and it is strict. Dive insurance with explicit hyperbaric cover is mandatory on both — the archipelago has a single chamber, in Puerto Ayora, and a boat transit from Darwin can run past 14 hours, so this is not a formality. Both carry a large primary oxygen bank plus portable units in the pangas, an AED, personal locator beacons and SMBs issued free, and satellite communications. Neither should be assumed to match any other boat in the fleet.
The headline dive-package price is never the whole number, on any liveaboard anywhere. What's separate from the package on every operator we book: your international flight to Ecuador, the $200 Galapagos National Park entry fee, the Galapagos Marine Reserve fee divers pay on top of standard park entry, the $20 INGALA transit control card, and — often — nitrox and gear rental, priced as add-ons rather than folded into the fare.
Current departures and starting prices are in the table below. Crew tips run in the same range divers see on naturalist cruises — $125 to $400 across a week-long trip, guest-paid regardless of which boat you're on.
Two cost items worth getting straight. Nitrox is not a surcharge on either boat: unlimited fills are included in the fare for certified nitrox divers, and if you are not certified you can take the course on board. Gear is the opposite — a full rental kit is charged by the week on both, and a dive computer is mandatory and rents separately, so bringing your own computer is the single easiest saving. We confirm the current rental rates for your boat when we quote.
"The headline price is the boat, and divers forget everything that sits outside it. Your kit is rented by the week unless you bring it, a dive computer is mandatory and rents separately, and the park fees and the marine reserve fee and the tips are all on top. The one thing that is not extra, and people always expect it to be, is nitrox — it is included on both boats if you are certified. Bring your own computer and get nitrox certified before you come, and you have saved the two costs that actually move."

Two seasons, two different dives. From roughly December through May, the warm/wet season brings calmer seas and warmer, clearer water — comfortable diving, if a little less dramatic. From June through November, the cool/dry Humboldt season takes over: colder, plankton-rich water, stronger current, and the payoff most liveaboard bookings are built around — the whale-shark aggregation at Darwin and Wolf, alongside the heaviest hammerhead activity of the year.
We can confirm the window: whale sharks show up June through November, with July through October carrying the highest probability of a sighting. Demand follows the sightings.
"Every year we see demand to travel during whale shark season grow, especially between July and October. Dive cruises have very few available spaces, and the best itineraries tend to get booked many months in advance. If seeing whale sharks is one of the main goals of your trip, I always recommend planning with enough lead time to get access to the best dates and vessels."
— Marcelo Guerrero, Co-Owner
We recommend booking 9 to 12 months out for peak-season dates on either Calipso Yacht or Galaxy Diver II — both run limited capacity, and the good weeks go first. Wildlife is wild, not scheduled: sightings during the window are frequent, but never guaranteed on any single trip. The two boats do differ seasonally on the western leg. Calipso switches route deliberately: January to May it runs Cabo Marshall on north-east Isabela for the giant oceanic mantas feeding in the warmer surface layer, and June to December, when visibility there drops, it shifts west to Cabo Douglas and Punta Vicente Roca for marine iguanas feeding underwater, penguins, flightless cormorants and Mola mola on the thermocline. Galaxy Diver II holds a fixed route year-round and alternates week by week between its dive itinerary and a naturalist cruise, so the sailing you want has to line up with the right week.

There's no single best — it depends on your logged-dive count, whether Darwin and Wolf's big-animal density is the whole trip or part of a broader route, and your cabin and camera-space priorities. We currently book two liveaboards for Galapagos dive trips, Calipso Yacht and Galaxy Diver II. If you are diving the Galapagos for the first time, Calipso is the easier introduction: the same three days north, slightly fewer dives, and the best camera-handling deck of the two. If the northern sites are the entire reason for the trip, Galaxy Diver II allocates more dives to Darwin and Wolf than anything else we book. And if you are travelling alone, Calipso is the one to ask about first, because it holds two single cabins.
Budget for the dive package itself, plus what's separate on every operator: international air, the $200 park entry, the added Marine Reserve fee, the $20 INGALA card, crew tips ($125 to $400 over a week), and often nitrox or gear rental as add-ons. Current departures and starting prices are in the table below.
Capacity varies by vessel, and we confirm the exact figure for Calipso Yacht and Galaxy Diver II before you book. Both carry a maximum of 16 divers, which is the national-park cap for a liveaboard, and both put two dive guides in the water so the group splits into eights. What's consistent is that these are small, dedicated trips built around Darwin and Wolf, not a large-group format.
Yes, effectively. Strong current, surge, negative entries, cold thermoclines, and visibility that shifts with the current make this advanced diving. The operators we book require Advanced Open Water certification, or the equivalent, plus 30 to 50 logged dives depending on the itinerary, and prior current-diving experience — some remote sites ask for more.
Both liveaboards we currently book — Calipso Yacht and Galaxy Diver II — run itineraries built around reaching Darwin and Wolf; naturalist cruises never make that crossing. Both give Darwin and Wolf three full days. Calipso sails Thursday to Thursday from San Cristóbal and logs 10 to 12 dives up north out of 17 to 19 for the week, with the balance on Carrion Point, North Seymour, Cousin's Rock and the western sites. Galaxy Diver II sails Wednesday to Wednesday from Baltra and dedicates 12 of its 19 dives to Wolf and Darwin, with the rest around Punta Carrion, Cape Marshall and Santiago.
June through November is the whale-shark window, with July through October carrying the highest sighting probability alongside the year's heaviest hammerhead activity — but colder water and stronger current come with it. December through May runs calmer and warmer, with easier conditions and less big-animal density. Neither season is wrong; it depends on what you're diving for.
A liveaboard is the only way to reach Darwin and Wolf — day-diving operators run from the central islands and can't make that crossing. If those two sites, and their hammerhead schools and whale sharks, are the goal, a liveaboard is the only route there. For central-island diving without the liveaboard commitment, our liveaboard vs. day diving, compared breaks down the trade-offs.
