Galápagos

The Galápagos sit roughly 1,000km off Ecuador in the Pacific, where cold and warm currents collide to feed one of the densest concentrations of large marine life divers go for. The draw splits in two. The northern islands, Wolf and Darwin, are the shark route: schooling scalloped hammerheads and, in the cool/dry season, whale sharks that are mostly large, apparently pregnant females. These are reachable only by liveaboard on 7–8 night itineraries. The central islands around Santa Cruz and San Cristóbal (Gordon Rocks, Cousins Rock, Kicker Rock) are day-diveable and add sea lions, marine iguanas feeding underwater, eagle rays and turtles. Two seasons drive everything: warm/wet (December–May, calmer, clearer) and cool/dry (June–November, cooler, plankton-rich, rougher, whale sharks). It is a UNESCO World Heritage Site and national park, and the diving is advanced, current-swept and cold-thermocline prone.

What makes it special

  • Darwin's Arch (the arch itself collapsed in 2021; now standing pillars, dived from El Arenal) and dense scalloped hammerhead schools
  • Whale sharks at Wolf and Darwin in the cool/dry season — predominantly large, apparently pregnant females
  • Marine iguanas foraging underwater and endemic Galápagos sea lions at the central islands
  • Mola (ocean sunfish) at cold-upwelling sites such as Punta Vicente Roca

Trip type

Liveaboard, Land based, Day trip

Price is per person for a typical trip, excluding international flights ($$$ = over $4,000).

Galápagos liveaboards are premium: a 7–8 night Wolf/Darwin trip commonly runs roughly $5,000–7,500+ per person depending on boat and cabin, excluding international flights. Mandatory government fees are additional and cash-only: the Galápagos National Park entrance fee is $200 per foreign adult (doubled from $100 on 1 Aug 2024) plus a $20 INGALA transit control card, about $220 total. Wolf and Darwin have no land-based or day-trip alternative.

Best time to dive

Best months Operating
Current
Strong
Water temp
16–27°C (coldest Aug, warmest Feb)
Visibility
1030m — Commonly 10–20m; clearer (15–30m) in the warm season, poorer in the plankton-rich cool season.
Getting there
Demanding Liveaboard only, with a 16h open-ocean crossing to reach the diving.
Experience
Advanced-only in practice. Central sites like Gordon Rocks typically require Advanced Open Water plus ~20 logged dives; Wolf/Darwin liveaboards recommend ~100 logged dives and experience with strong currents, surge and negative entries.

Nearest airports

  • GPSSeymour Airport (Baltra) (Main arrival airport, reached via Quito (UIO) or Guayaquil (GYE) on the Ecuadorian mainland; liveaboards board near Baltra/Santa Cruz)
  • SCYSan Cristóbal Airport (Secondary entry point via Quito or Guayaquil)

Permit required

A National Park entrance fee and an INGALA transit control card are mandatory for all visitors. Diving within the Galápagos Marine Reserve is only via licensed operators and liveaboards.

National Park entrance ~$200 per foreign adult ($100 under-12), effective 1 Aug 2024; INGALA transit card ~$20 per person; about $220 total, cash (USD) only.

Schools are present year-round at Wolf, Darwin, Gordon Rocks and Kicker Rock. Sources genuinely conflict on the densest months — warm-season (calmer, clearer) versus cool-season upwelling — so this is coded reliable year-round rather than a single peak.

Dive sites

Worth knowing before you book

  • Wolf and Darwin are liveaboard-only — no land-based or day-trip option, and reaching them means overnight open-ocean crossings that can be rough and cause seasickness.
  • Strong, unpredictable currents and surge; the famous hammerhead and whale-shark encounters happen in current and are never guaranteed.
  • Cold thermoclines (drops of up to ~5°C) mean thick exposure protection — commonly 7mm plus hood and gloves in the cool season.
  • Advanced-only; operators expect current experience and, for Wolf/Darwin, high logged-dive counts.
  • High total cost and access friction: premium liveaboard fares, long-haul flights via Quito or Guayaquil, plus about $220 in mandatory cash park and transit fees.

This is a researched draft, not yet human-verified. The seasonality and logistics are drawn from the sources below — confirm specifics (permits, fees, closures) with an operator before you book.

Note on the data: Hammerhead peak months are a genuine source conflict (warm-season operators vs cool-season tracking studies), so hammerheads are coded reliable year-round rather than a single peak. Site coordinates are approximate island-level positions. Park fee ($200) is well corroborated by conservation orgs and operators but not fetched from a primary government page. Water temperature not published per-month. Water temperature: maxC tracks published monthly surface averages (warm/wet Dec-May vs cool/dry Jun-Nov), while minC reflects the archipelago's cold thermoclines and upwelling, which in the cool season and at Wolf/Darwin and the western islands routinely drop water into the high-to-low teens well below the surface reading; minC values are interpolated to capture that swing, not measured surface temps. Access: The north (Wolf/Darwin) shark diving is liveaboard-only: fly mainland Ecuador (Quito/Guayaquil) to Baltra/San Cristobal, board near the central islands, then an overnight open-water crossing of roughly 16+ hours reaches Wolf and Darwin; central-island sites near Santa Cruz are day-diveable and land-based.
