Diving the Galápagos: What You Need to Know

Best season: Jun–Nov (whale sharks) · Dec–May (warmer, calmer)
Water temp: 16–28 °C (varies by season and island)
Visibility: 10–25 m
Difficulty: Advanced
Beginners: Only with experience
Liveaboard: ~US$5,000–9,000+/week

About 1,000 km off the coast of Ecuador, the Galápagos Islands sit where several ocean currents meet, including the cold, nutrient-rich Humboldt and Cromwell currents. The result is an extraordinary concentration of marine life, much of it found nowhere else on Earth.

Why the Galápagos is for experienced divers

Strong currents and surge. Divers often hold on to rocks with gloves or use a reef hook (where allowed) while watching sharks pass.
Negative entries and blue-water drifts in open ocean.
Cold water and thermoclines, sometimes below 20 °C, which require 7 mm suits with hood and gloves.
Remote location: evacuation and chamber access are far away.

Most liveaboards heading to Wolf and Darwin require at least Advanced Open Water certification and 30–50+ logged dives, ideally including drift and cold-water experience. Nitrox is recommended and often included.

Main dive areas

Wolf and Darwin islands

The legendary northern islands, visited only by liveaboards. Famous for:

Huge schools of scalloped hammerhead sharks
Whale sharks, especially large females, mainly June–November around Darwin
Silky and Galápagos sharks, eagle rays, dolphins, turtles and giant schools of jacks and tuna

Note: Darwin's Arch collapsed in 2021, leaving two pillars ("the Pillars of Evolution"); the dive site underwater remains outstanding.

Central and western islands

Cabo Marshall (Isabela): manta rays.
Punta Vicente Roca and Cabo Douglas (Fernandina): cold upwelling sites where you may see marine iguanas feeding underwater, flightless cormorants, Galápagos penguins and mola mola.
Gordon Rocks and North Seymour: day-trip sites from Santa Cruz with hammerheads, sea lions and whitetip reef sharks. Gordon Rocks is known for strong currents.
Kicker Rock (León Dormido): from San Cristóbal, with sharks, rays and sea lions.

When to go

Season	Water	Highlights
Jun–Nov (cool/"garúa" season)	16–23 °C	Whale sharks at Darwin, more plankton and big schools, rougher seas
Dec–May (warm season)	22–28 °C	Calmer seas, better visibility at times, hammerheads, manta rays

Options for less experienced divers

If you're a new diver but going to the Galápagos anyway, you can:

Do land-based day trips from Santa Cruz or San Cristóbal to easier sites, choosing operators that match dives to experience
Snorkel, which is spectacular in itself, with sea lions, turtles, penguins and marine iguanas
Build experience first with an Advanced course, drift dives and cold-water dives elsewhere, then come back for the northern islands

Costs (2026, approximate)

8-day liveaboard including Wolf and Darwin: about US$5,000–9,000+
Galápagos National Park entrance fee for foreign visitors: US$200 (increased in 2024) plus a transit card
Day-trip dives from Santa Cruz: about US$200–300 for two dives
Flights via Quito or Guayaquil

Practical tips

Bring or rent a 7 mm suit with hood and gloves
Carry an SMB and a signalling device; many boats provide GPS locator beacons
Get comprehensive dive insurance with evacuation cover
Book liveaboards up to a year ahead

Typical Galápagos liveaboard itinerary

Day	Typical plan
1	Fly to Baltra or San Cristóbal; check-in dive (often at North Seymour or Punta Carrión)
2	Central islands, then an overnight crossing north
3–5	Wolf and Darwin: 3–4 dives a day with hammerheads, sharks, whale sharks (seasonal)
6	Cabo Marshall (mantas) or Fernandina / Isabela (marine iguanas, penguins, mola mola)
7	Final dives and a land visit (for example, giant tortoises on Santa Cruz)
8	Disembark and fly out (after a full no-fly interval)

How to prepare

Complete Advanced Open Water, Nitrox and ideally Drift training
Log 30–50+ dives, including some in current and in cooler water
Practise deploying an SMB from depth until it's routine
Practise negative entries and fast group descents with a guide
Get your own well-fitting 7 mm suit, hood and gloves

Frequently asked questions

Can beginners dive in the Galápagos?

Beginners can do some easier day-trip dives with suitable operators, but the famous northern islands (Wolf and Darwin) are for experienced divers with Advanced certification and typically 30–50+ logged dives.

When is the best time to see whale sharks in the Galápagos?

Mainly June to November, especially around Darwin Island.
