Galápagos: the Pacific archipelago that taught us evolution

It’s 7:14 a.m. on a small black-sand beach on Fernandina Island, the most westerly of the Galápagos, and a marine iguana about a metre away from me is, with no apparent interest in my presence, working through the morning ritual of warming up on a rock. The iguana has been here forever, on terms that include no fear of human beings. A Galápagos sea lion is sleeping fifteen metres further on. Two flightless cormorants are drying their absurd vestigial wings in the sun. This is the experience the Galápagos offers and offers nowhere else: animals that have no reason to flee you.

Why I keep coming back

The Galápagos archipelago — 19 main islands and over a hundred smaller ones, scattered across 800 km of Pacific Ocean 1,000 km off the coast of Ecuador — is one of the world’s great evolution laboratories. Charles Darwin spent five weeks here in 1835; the observations led, decades later, to On the Origin of Species. The islands have remained, by global standards, very lightly disturbed. About 97% of the archipelago is national park.

The wildlife is the trip. Marine iguanas (the only sea-going lizards on earth), Galápagos giant tortoises, blue-footed boobies, frigatebirds, Galápagos penguins (the only equatorial penguin), Galápagos sea lions, Galápagos hawks, the famous finch species that gave Darwin his clue. The animals are not just visible — they are accessible at a distance that is genuinely surreal.

How to visit

Two formats:

Live-aboard cruise: 4 to 15 nights on a small expedition vessel (8–100 passengers). The vessel moves between islands at night, with each day’s activities (snorkelling, walks, panga-boat tours) led by licensed naturalist guides. This is the way to see the more remote islands.

Land-based: Stay on Santa Cruz, San Cristóbal, or Isabela (the inhabited islands) and take day-boat tours. Cheaper and slower; access to fewer remote islands.

The trade-off: the cruise format is significantly more expensive but lets you visit the western islands (Fernandina, Isabela’s western coast, Genovesa for birding), which are off-limits from the inhabited islands.

Where to base yourself / which cruise

Land-based: Puerto Ayora on Santa Cruz is the largest town and best base. Smaller boutique hotels (Pikaia Lodge, Royal Palm) are the upper-end land options.

Cruise tier: Operators range from upper-budget (US$3,500–5,000 per person for a 5-day trip) through mid-range (US$5,000–8,000) to luxury (US$8,000–15,000+). Lindblad/National Geographic, Ecoventura, Aqua Expeditions are some of the established options. The smaller vessels (16 passengers) often have better access to landing sites than the larger ones (100 passengers); the larger vessels have more amenities.

What you’ll see (a representative cruise itinerary)

Day 1: Fly from Quito or Guayaquil to Baltra; transfer to ship. Day 2: Genovesa Island — red-footed boobies, frigatebirds, fur seals. Day 3: Bartolomé Island — the iconic Pinnacle Rock photo; snorkelling with sea lions; possibly Galápagos penguins. Day 4: Fernandina and Isabela islands’ western coast — marine iguanas, flightless cormorants, possible Galápagos hawks. Day 5: Santa Cruz highlands — giant tortoise sanctuary; Charles Darwin Research Station; flight home next morning.

Variants are many.

Where to eat

On the cruises, all meals are provided and quality varies by operator. On land, the seafood in Puerto Ayora is fresh — The Rock and Almar are reliable mid-range; Isla Grill for the casual.

When to come

Year-round destination: temperatures are equatorial-mild year-round.

June to November is the cooler/drier season — better for seabird breeding (boobies, frigatebirds), the Humboldt Current is strong (better for snorkelling with marine iguanas and penguins). The water is cooler (a wetsuit is more important).

December to May is the warmer/wetter season — better for terrestrial wildlife (the giant tortoises are active), warmer water, but more variable visibility for snorkelling.

Major events: green turtle nesting in January–March; sea lion pupping in August–October.

Practical notes

• Visa: Ecuador offers 90 days visa-free for most Western passports.
• Money: Ecuador uses the US dollar. ATMs in Puerto Ayora.
• Park entry: US$200 for non-Ecuadorians (recently increased from US$100) plus US$20 for the transit card. The fees go directly to conservation.
• The flight: From Quito or Guayaquil to either Baltra (GPS) or San Cristóbal (SCY). Around 90 minutes from Guayaquil.
• Wildlife rules: Stay 2 m from animals (less for some species; the guides will brief). No flash photography. No food on the islands. The rules are strict and they matter.
• Health: Galápagos itself is healthy; the mainland Ecuador may require yellow-fever vaccination depending on your route.
• Cost: A genuine deep Galápagos trip is one of the most expensive trips in this guide on a daily basis. Budget US$1,000–2,000 per person per day for a quality cruise, less for the land-based experience.

A final thought

The Galápagos are one of the few destinations that consistently exceed every expectation I have brought to them. The proximity to the wildlife, the geological strangeness of the volcanic islands, the snorkelling with sea lions and marine iguanas and the occasional reef shark — all of these produce experiences that genuinely cannot be replicated elsewhere on earth.

The trip is expensive. The conservation rules are tight. The number of visitors is limited. All of this is the right approach to one of the planet’s most consequential ecological reservoirs.

If you can afford the cruise, do the cruise. Pick a smaller ship (under 20 passengers) for the more intimate access. Bring a polarising filter for your camera and an underwater housing for the snorkelling. Spend the money. The Galápagos do not disappoint and they will not, in their current state, last forever.
