Galapagos liveaboard diving: boats, routes and requirements
Compare Galapagos diving programmes by Wolf and Darwin time, embarkation airport, conditions, Nitrox rules and inclusions before choosing a dated departure.
Choose a diving programme, not a naturalist cruise
For Galapagos liveaboard diving, shortlist dedicated dive boats by the sites and time they allocate, then check experience requirements and the correct island airport. Galapagos Sky’s seven-night sample starts and finishes at San Cristobal (SCY) and allocates three full days to Wolf and Darwin. Galapagos Aggressor III’s published seven-night schedule uses Baltra (GPS) and runs Thursday to Thursday. The airport difference alone can make an otherwise plausible booking unworkable.[3][6] These are specialist diving programmes, not interchangeable wildlife cruises with optional scuba. Galapagos Sky describes advanced conditions and restrictions on snorkeling at most dive sites. A non-diving partner should not expect a full snorkeling itinerary alongside the diving.[4]

| Compare | Galapagos Sky [3][4][5] | Galapagos Aggressor III [6] |
|---|---|---|
| Standard seven-night schedule | Sunday to Sunday, San Cristobal (SCY) | Thursday to Thursday, Baltra (GPS), home port Itabaca Channel |
| Longer option | Ten-night programme with five Wolf/Darwin days; different embarkation and disembarkation islands | The reviewed Know Before You Go document describes the seven-night trip |
| Nitrox | Included in the seven-night rate; recognised certification required; no course onboard | Additional fee; Nitrox course is listed, subject to instructor confirmation and required forms |
| Night diving | Optional Wolf night dive, conditions permitting and with experience/equipment requirements | Reviewed document says no night diving |
| Flight-planning priority | Match SCY round trip or the specific mixed-island ten-night route | Match GPS transfers and Thursday arrival/departure instructions |
Wolf and Darwin: count the actual days
Galapagos Sky’s seven-night sample spends Tuesday to Thursday at Wolf and Darwin. Other days include North Seymour and Cousins Rock, the western islands of Fernandina and Isabela, and Pinzon with a Santa Cruz land visit. Its published comparison gives the ten-night programme five Wolf/Darwin days and an additional Cabo Marshall/Roca Blanca dive day. The extra nights change northern-island time, not just cabin time.[3] Sky’s FAQ says it visits Wolf and Darwin throughout the year. Do not apply that promise to other boats. Aggressor’s May 2026 document describes seasonal route changes, with Wolf and Darwin in its cool-season discussion and closer sites in the warm-season discussion. Treat the route attached to your named departure as decisive, especially if the northern islands are the reason for travelling.[5][6]
[5] Galapagos Sky: year-round programme and FAQAggressor III: useful differences and unresolved document details
Aggressor’s current Know Before You Go document establishes its Baltra home port, Thursday schedule, recreational non-decompression diving and paid Nitrox. It also contains inconsistent dive totals: approximately 19 dives in its summary and 21–24 in its itinerary detail. Do not use either number as a guaranteed delivered total.[6] The same document is not consistent about onboard training: one section says Nitrox is the only course, while a later generic section lists Advanced Open Water too. If training is part of your plan, obtain written confirmation of the exact course, instructor availability and prerequisites for your departure. Do not book this demanding trip on the assumption that an advertised course will supply the experience you lack.[6]
[6] Aggressor III: Know Before You Go, updated May 2026Who should consider these trips?
Galapagos Sky describes strong currents, variable visibility, cooler water and typical dive depths around 20–30 metres. It recommends 50–100 open-water dives, current experience and the ability to manage tender entries and exits in choppy water; recent diving is required. That recommended range is not a universal Galapagos legal minimum and does not amount to individual clearance.[4] If your experience is limited to warm, sheltered dives, build relevant skills before committing to this itinerary. Send your actual dive history to the operator for a departure-specific assessment. Its acceptance, your certification limits and appropriate medical advice remain separate questions; a spacious boat or private guide does not make the conditions easier.[4]
[4] Galapagos Sky: conditions and diver experienceNitrox certification can determine which dives you join
Galapagos Sky requires recognised enriched-air certification and the card at check-in; it does not teach Nitrox onboard. Its diving page says divers without certification cannot dive on days three, four and five at Wolf and Darwin and must hire a private guide. Its FAQ instead says not all dives can be completed on those days. Those descriptions are not equivalent.[4][5] If you are not already qualified, resolve that discrepancy with the operator before paying, and complete any agreed training before travel. Do not interpret included Nitrox as permission to use it, or the guide fee as a way around certification. Aggressor’s paid Nitrox/course arrangement is a different operator policy, not evidence that Sky offers the same option.[6]
[4] Galapagos Sky: Nitrox restrictions and certificationSeason: trade warmer water against cooler-season priorities
Galapagos Sky distinguishes warmer December–May conditions from cooler June–November conditions and associates the cooler period with whale sharks. Its seven-night page gives broad water-temperature ranges of 18–27°C and 15–25°C respectively, while its FAQ gives slightly different ranges. Treat them as approximate planning bands, not a water-temperature forecast.[3][5] The operator also notes warmer water around Wolf and Darwin than at western, southern and central sites. Plan exposure protection for the full route, including its colder dives. Wildlife remains a possibility rather than a guaranteed encounter, and a generally calmer season does not remove the need for current experience.[3][4][5]
[3] Galapagos Sky: seasonal and site temperature guidanceFlights: SCY and GPS are different bookings
For Sky’s seven-night cruise, match San Cristobal (SCY) at both ends. Its ten-night trips use different islands for embarkation and disembarkation, for example SCY to Santa Cruz/Baltra (GPS), or the reverse. Buy flights only after the operator confirms your departure’s exact direction.[3] For Aggressor III, the reviewed instructions specify Baltra (GPS), a Thursday arrival and airport assistance to the yacht at Itabaca Channel. They advise reaching Quito or Guayaquil the night before the Galapagos flight. Keep international arrival, domestic island flights and the cruise’s transfer window as separate itinerary steps. Do not infer a safe post-diving flight interval from the check-out time alone.[6]
[6] Aggressor III: airport, arrival and transfer instructionsWhat is outside the cruise fare?
Sky’s seven-night published rate includes accommodation, meals, beverages, standard tank and weights, guiding, Nitrox and island airport/dock transfers on departure dates. It excludes international and domestic flights, insurance, rental gear, gratuities and listed park, transit-card and hyperbaric-chamber charges.[3] Aggressor lists a separate fuel surcharge, paid Nitrox and VAT on onboard purchases other than gratuities in its May 2026 document. Obtain a current itemised quote rather than transferring Sky’s inclusions to Aggressor or using either boat’s base fare as the holiday budget. Confirm each compulsory fee, its payment location and currency for your booking.[6]

First establish whether you have the experience for the conditions. Then compare northern-island days, exact ports, dates and the itemised total. Only after that should you compare cabin position, bed arrangement and occupancy basis. Source review: 24 October 2026.
