Galápagos Marine Reserve, Ecuador
Galápagos
Volcanic archipelago on the equator where the cold Humboldt and Cromwell currents meet warm tropical water, producing large-animal diving in cold green water alongside endemic species found nowhere else.

Season
When this place works
Open year-round with no closure; the split is a quality trade, not an access one. Cool season (Jun-Nov) means whale sharks, big-animal density, cold water and rough seas. Warm season (Dec-May) means calmer water, better visibility, more…
Why dive here
What this place is known for
01sharkSchooling scalloped hammerheads at Darwin and Wolf
Schools that can run over 100 animals circling the northern seamounts. Reaching Darwin and Wolf requires a liveaboard; they are far north of the inhabited islands and are not accessible on a day trip from Santa Cruz.

02pelagicPregnant whale sharks
Surprise relative to the headline, and a genuinely unique claim. Unlike every other whale shark aggregation on earth, which is dominated by immature males, the Galápagos animals are overwhelmingly large mature females with distended abdomens consistent with…

03cold waterEndemic cold-water species on the equator
Under-marketed relative to the sharks. Marine iguanas grazing algae underwater, Galápagos penguins, flightless cormorants and Galápagos fur seals, all at 0 degrees latitude. These are central-island dives, not Darwin and Wolf, and a shark-focused itinerary…
Marine life
Twelve-month species timelines
Present year-round at Darwin and Wolf. Schooling behaviour is reported strongest in the warm season (Dec-May); the reason for the aggregation is still debated in the literature. Note this cuts…
Jun-Sep per Galapagos Conservation Trust, Jul-Oct per liveaboard sources; encoded as the union with Jul-Oct as peak. Almost exclusively at Darwin. Mature pregnant females, unlike every other known…
Endemic. Actively interactive with divers, particularly juveniles, and reported as more playful in the warm season.
The only marine lizard on earth. Grazes algae underwater at shallow central-island sites; reported as more active in the warm season when the water is less punishing for a cold-blooded animal.
Associated with the cold-season upwelling. Occasional rather than expected.

Cold, surgy and current-swept, and nothing about it resembles tropical diving. Cool season (Jun-Nov) drops to 16-18C with sharp thermoclines, strong current and rougher surface conditions; a 7mm with hood and gloves is the working minimum.…
Entries — boat
Recommended & required
- nitrox — recommended. Standard on dive liveaboards.
- drysuit — recommended. Not required, but cold-season water at 16-18C over multiple daily dives defeats most wetsuits. Many repeat visitors bring one.
