Galápagos Islands

A volcanic archipelago roughly 1,000 km off Ecuador's coast, famous for wildlife unafraid of humans and for its part in Darwin's theory of evolution. UNESCO inscribed it in 1978 as a "living museum and showcase of evolution", and it remains one of the most tightly regulated places a traveller can visit.

The numbers explain why. The archipelago counts 127 islands, islets and rocks, of which 19 are large and only four are inhabited. The national park, declared in 1959, covers 97% of the land surface, and the surrounding marine reserve extends across roughly 133,000 km². Almost everything you will want to see sits inside a protected area, and protected areas here come with rules.

The animals do not run away. That single fact, a consequence of evolving without land predators, is what separates Galápagos from every other wildlife destination: sea lions sleep on benches, marine iguanas ignore you on the path, and blue-footed boobies nest beside marked trails rather than at the end of a telephoto lens.

The biology behind it is genuinely exceptional rather than marketing language. UNESCO records around 500 vascular plant species, 180 of them found nowhere else, and 2,909 marine species with an endemism rate above 18%. Three ocean currents converge here, which is why you can snorkel with tropical fish, penguins and cold-water species on the same trip.

• Snorkelling from a panga or a beach landing. The confluence of currents means sea lions, rays, reef fish and often Galápagos penguins in the same water. For most visitors this, not the land walks, is the memory that lasts.
• Giant tortoises in the highlands of Santa Cruz. Wild tortoises move freely through farmland and reserve on the wetter upper slopes, a very different encounter from seeing them in a breeding centre.
• A marked trail walk at a landing site, with a naturalist guide explaining what you are looking at. Guides are compulsory in protected areas, and a good one turns an unremarkable stretch of lava into the clearest field lesson in evolution you will get.
• Volcanic landscape on Isabela or Bartolomé. The archipelago is geologically young and still active, and the lava fields make the "islands as work in progress" point better than any exhibit.
• Seabird colonies in season. Boobies, frigatebirds and, on the outer islands, waved albatross. What is nesting depends heavily on the month, which is the main argument for choosing dates around wildlife rather than weather.

June–November for cooler water and marine life; December–May for warmer, calmer seas.

Puerto Ayora on Santa Cruz is the largest town and has the widest choice of accommodation, restaurants and tour agencies. It is the practical base if you want to book day trips after arriving rather than in advance.

Puerto Baquerizo Moreno on San Cristóbal is quieter, with sea lions occupying much of the waterfront, and suits travellers who want a town that feels less oriented around tourism. Puerto Villamil on Isabela is smaller and more rural, and is the best base for volcanic landscapes and slow days.

On a cruise, the boat is the accommodation, and the size of the vessel matters more than its rating: smaller boats reach landing sites that larger ones cannot, and group sizes at visitor sites are regulated.

There is no way in except by air from mainland Ecuador. Flights depart from Quito or Guayaquil to one of two airports: Seymour on Baltra, which serves Santa Cruz via a short ferry and bus transfer, or San Cristóbal, which lands you a few minutes from the town of Puerto Baquerizo Moreno.

Which airport you want is decided by your itinerary, not by price. Cruises specify an embarkation island, and arriving at the wrong one is an expensive mistake. If you are travelling independently, San Cristóbal puts you in a town immediately, while Baltra involves a transfer of roughly an hour and a half before you reach Puerto Ayora.

Baggage is screened for organic material before you leave the mainland. Introducing food, animals or plants to the archipelago is prohibited, and this is enforced at the airport rather than treated as advice.

Distances between islands are significant and there is no road network connecting them. Two models dominate, and they produce very different trips.

A live-aboard cruise sails overnight, which is the only practical way to reach the outer islands (Genovesa, Española, Fernandina) where much of the distinctive wildlife is. You wake up at a new landing site, and guiding is built in.

Island-hopping from a base uses public inter-island speedboats between the inhabited islands (Santa Cruz, San Cristóbal, Isabela, Floreana) and day tours from town. It is more flexible and usually cheaper, but you spend more time in transit and the outer islands stay out of reach.

On the inhabited islands themselves, towns are walkable, with pickup taxis for the highlands and water taxis in the harbours.

Food on the islands is simpler than visitors expect. Ecuadorian staples dominate: soups, rice, plantain, and fish landed locally. In Puerto Ayora, the open-air kiosks on Charles Binford street are where residents eat in the evening, and the catch of the day is genuinely the day's catch.

The four inhabited islands hold a permanent population living under constraints most communities never face: limits on construction, on fishing, on what can be imported. Understanding that the islands are a working place with residents, not only a nature reserve, changes how the rules read. They exist because roughly 97% of the land is national park and the people live in the remaining fraction.

Galápagos is expensive by design rather than by accident: visitor numbers are capped, guiding is compulsory, and almost everything is shipped from the mainland. The single biggest decision is cruise versus land-based, and it can change the total by a factor of several.

What drives the cost, in rough order: the boat or accommodation, the mainland flights, the park entrance fee and transit card, and day tours if you are land-based. Food and local transport are minor by comparison. Booking a cruise last-minute from Puerto Ayora is a long-standing way to pay less, but you take whatever route and dates are unsold.

Two formalities apply on top of Ecuador's normal entry rules: a transit control card obtained before boarding on the mainland, and a national park entrance fee collected on arrival. Both are administrative rather than optional, and the amounts are set by the Ecuadorian authorities and revised periodically. Check the current figures before you travel.

The rule that shapes your whole trip is different: visitors to protected areas must be accompanied by a naturalist guide authorised by the national park directorate. You cannot simply walk into a visitor site alone. In practice this means either a cruise, where guiding is included, or day tours booked from town if you are staying on land.

Camping is permitted only in designated areas and requires authorisation requested at least 48 hours in advance. Recreational fishing is allowed only from tour boats authorised by the park.

The park rules are specific and enforced. The ones visitors most often break by accident:

• Stay at least two metres (six feet) from wildlife, even when an animal approaches you, and they do.
• Never feed wildlife. It causes health problems for the animals.
• No flash photography with wildlife. Commercial photography needs prior authorisation.
• Remain on marked trails at visitor sites and respect signage.
• Take nothing. Souvenirs made from black coral, shells, lava rock, animal parts or native wood or vegetation are prohibited.
• No drones. Aerial tourism activities, motorised water sports and mini-subs are not permitted in the park or the marine reserve.
• Pack out all rubbish.

Crossings between islands are open-water passages on small boats and are frequently rough. If you are prone to seasickness, plan for it rather than hoping.

Five days, land-based. Two nights Santa Cruz with a highlands tortoise excursion, two nights on Isabela for volcanic landscape and calmer snorkelling, returning via Santa Cruz. Short, but it works.

Eight days, land-based. The same with San Cristóbal added, and a day tour to an uninhabited island such as Bartolomé or North Seymour. This is the sweet spot for independent travellers.

Eight days, cruise. The only realistic way to reach the outer islands. Itineraries are fixed and approved by the park, so choose the boat by the islands on its route, not the other way round.

Whatever the length, allow a buffer day on the mainland before your international flight home. Inter-island and mainland flights are weather-dependent and a missed connection here is expensive.
