🇪🇨 Ecuador · Galápagos
San Cristóbal has a special aura within Galápagos: it is the easternmost island, the first to see the sun rise, the political capital of the archipelago and, above all, one of the places where Charles Darwin first came ashore in 1835. Walking around its capital, Puerto Baquerizo Moreno, means stepping into a quieter, more genuine version of Galápagos, where sea lions are not a distant attraction but neighbors: they sleep on the malecón benches, on the piers and on the town beaches, living alongside people in a way that surprises every visitor.
The island blends history, science and adventure perfectly. At the Centro de Interpretación you get the full story of the islands —their geology, their wildlife, the arrival of humans and the conservation challenges—, and a few steps away, the trail to Cerro Tijeretas leads to an unforgettable snorkeling bay under the flight of the frigatebirds. But the jewel of San Cristóbal is out at sea: León Dormido (Kicker Rock), an imposing volcanic rock split in two that rises from the ocean and is one of the most iconic diving and snorkeling sites in the world, with sharks, rays and turtles.
This guide covers San Cristóbal with a practical, warm eye: how to fly in direct, what to see in town and in the highlands, the best beaches with sea lions, the diving trips and how to do it all responsibly. Remember that Galápagos is a fragile, protected ecosystem: there are compulsory entry fees, sites you can only visit with an authorized naturalist guide and strict rules of conduct. Following them is what keeps this evolutionary paradise alive.
The history of San Cristóbal is that of the whole archipelago, with a leading role of its own. The Galápagos were discovered by chance in 1535, when the ship of the Dominican friar Tomás de Berlanga was swept by the currents to these uninhabited islands; the giant tortoises ('galápagos') would give them their name. Between the 17th and 19th centuries, pirates, whalers and sealers used the islands as a refuge and a larder, taking away tens of thousands of tortoises and leaving invasive species behind. In 1832, General José de Villamil took possession of the archipelago for independent Ecuador, which named it the 'Archipiélago del Ecuador'. In 1835, HMS Beagle reached Galápagos and San Cristóbal (then called Chatham) was one of the first islands the young Charles Darwin set foot on, and his observations would be key to his theory of evolution by natural selection. San Cristóbal was one of the earliest islands to be settled: at the end of the 19th century, the businessman Manuel J. Cobos set up the El Progreso sugar mill there, running a near-feudal, abusive regime over the workers that ended in his murder. Over time, Puerto Baquerizo Moreno grew until it became the capital of the province of Galápagos. In 1959, Ecuador declared 97% of the territory a National Park; in 1978, Unesco made Galápagos its first Natural World Heritage Site. The full story is on our history page.

Origins, formation and what the sources say.
The written history of the Galápagos —and of San Cristóbal, its easternmost island— began by chance. In 1535, the Dominican friar Tomás de Berlanga, bishop of Panama, was traveling to Peru on the orders of King Charles I of Spain to mediate in the conflicts among the conquistadors. Midway through the voyage, his ship was caught in a windless calm and swept out to sea by the currents, until it came upon an archipelago of arid, uninhabited islands that nobody expected to find.
Berlanga described the find in a famous letter to the king: a landscape of lava and stone that seemed cursed, with very little fresh water, but inhabited by extraordinarily tame animals —enormous tortoises, iguanas and birds that did not flee from people—. That lack of fear, the result of having evolved without human predators, was an oddity that at the time only caused astonishment, but that centuries later would make the islands a scientific treasure with no equal.
For a long time the islands were recorded as an inhospitable place of no value to the Crown, appearing on nautical charts as the 'Islas Encantadas', the enchanted islands, partly because of the strong currents and mists that made them hard to locate and gave the impression that they appeared and disappeared. The name 'Galápagos' referred to the giant tortoises. San Cristóbal, like the rest of the archipelago, would remain practically unpopulated for centuries, until history touched its shores again.
For more than two centuries, the Galápagos had no permanent population, but they did have visitors who left a deep mark on their wildlife. From the 17th century, the islands became a refuge for pirates and privateers —many of them English— who attacked the Spanish galleons carrying riches across the Pacific, making use of the archipelago's sheltered anchorages and hiding places. Later came the whalers and sealers, who turned the islands into a regular stop.
The great resource the islands offered was tragic for their wildlife: the giant tortoises. These could survive many months without eating or drinking, which made them ideal 'live food' for long sea voyages. Pirates, whalers and sealers loaded them by the hundred into their ships' holds as a store of fresh meat. It is estimated that between the 17th and 19th centuries tens of thousands of tortoises were taken from the various islands, pushing several populations to the brink of extinction, San Cristóbal's among them.
To that plundering was added another lasting threat: the introduction of foreign species. Goats, pigs, dogs, cats, rats and donkeys, brought in or escaped from the ships, went feral and destroyed the native vegetation, preyed on eggs and hatchlings and competed with the native animals. Those invasive species are still today one of the greatest threats to Galápagos wildlife, and controlling and eradicating them is a central task of conservation work on islands like San Cristóbal.
The political and scientific fate of San Cristóbal was settled within a few years. On 12 February 1832, the government of newly independent Ecuador formally took possession of the archipelago, which was officially renamed the 'Archipiélago del Ecuador'. The key figure was General José de Villamil, who pushed the annexation through and founded the first colony on Floreana island. Thanks to that act, when HMS Beagle arrived three years later, the Galápagos were already Ecuadorian territory.
In September 1835, the British Navy ship HMS Beagle reached the archipelago on its round-the-world voyage. The first island it touched —and where the young naturalist Charles Darwin, aged 26, came ashore— was precisely San Cristóbal, then called 'Chatham' by the English. Darwin walked its volcanic ground, observed the tame wildlife, collected specimens and began taking the notes that in time would feed his ideas. That is why a monument to Darwin crowns Cerro Tijeretas today, recalling that first contact.
It was on these islands that Darwin noticed that species varied from one island to another —the tortoises by their shells, the birds by their beaks— as if nature had 'experimented' separately on each one. He did not formulate his theory there, but years later, and yet the Galápagos have been forever linked to the evolution by natural selection he published in 1859 in 'On the Origin of Species'. San Cristóbal carries the pride of having been Darwin's gateway into this living laboratory.
San Cristóbal is the setting for one of the darkest chapters in the human history of Galápagos. At the end of the 19th century, the Ecuadorian businessman Manuel J. Cobos established a farming and industrial colony in the island's highlands around a sugar mill, at the place known today as El Progreso. The enterprise came to have hundreds of workers and to produce sugar and other goods that were exported to the mainland, and for a time it was the most important settlement in the archipelago.
But El Progreso ran on a near-feudal, deeply abusive regime. Cobos governed the island like an absolute lord: many workers had been brought in under false pretenses or as convicts, they were paid in a currency of his own that was only good at the company store (a system of debt bondage) and the punishments were cruel, including banishing people on deserted islands. The build-up of abuses ended the way tyranny usually ends: in 1904, the workers themselves rose up and murdered Cobos.
Beyond its harshness, this story shows how the settlement of Galápagos was marked by difficult and sometimes violent colonization experiments: farming colonies, penal colonies and projects that ran up against the isolation and the harshness of the environment. San Cristóbal, however, stayed populated and kept growing, and its capital, Puerto Baquerizo Moreno, would eventually become the administrative center of the islands. Those traces of El Progreso are part of the story told today at the island's Centro de Interpretación.
As the 20th century went on, San Cristóbal cemented a central role in the political life of the archipelago. Its main coastal settlement, Puerto Baquerizo Moreno —named after an Ecuadorian president—, grew as a port and administrative center. When, in 1973, the Galápagos were raised to the status of a province of Ecuador, Puerto Baquerizo Moreno was designated its capital, a position it still holds today.
That means that although Santa Cruz (with Puerto Ayora) is the most populated island and the archipelago's great tourist center, San Cristóbal is the seat of the provincial government and of a good share of the public institutions, as well as having a naval and military presence. Being the capital gives Puerto Baquerizo Moreno a somewhat more institutional, quieter air, unlike the tourist bustle of Puerto Ayora.
The island also developed a tourist identity of its own, built on its direct air link from the mainland (with an airport of its own), its famous coexistence with the sea lions right in town, its beaches and, above all, its world-class dive sites such as León Dormido (Kicker Rock). San Cristóbal is also home to a university campus focused on Galápagos research, reinforcing its bond with science. Today it is one of the four inhabited islands in the archipelago and combines its role as capital with the permanent challenge of balancing population, tourism and conservation.
In the middle of the 20th century, the world woke up to the unique value of the Galápagos and to the threats stalking them. The key year was 1959: coinciding with the centenary of Darwin's 'On the Origin of Species', Ecuador declared about 97% of the archipelago's land area the Galápagos National Park, leaving only 3% for the populated areas such as Puerto Baquerizo Moreno. That same year the Charles Darwin Foundation was created, under the auspices of Unesco and the IUCN, and in 1964 it would open its Research Station on Santa Cruz.
International recognition came in 1978, when the Galápagos became the first site in the world inscribed on Unesco's list of Natural World Heritage Sites. Later, the archipelago was also declared a Biosphere Reserve and the Galápagos Marine Reserve was established, one of the largest protected marine areas on the planet, which embraces emblematic dive sites such as León Dormido.
Today, San Cristóbal —like all of Galápagos— faces the constant challenge of balancing the lives of its people, tourism and conservation. The tools for that include the National Park entry fee (updated in 2024) and the Transit Control Card, which regulate and fund the protection of the islands; the invasive species eradication programs; the rearing and repatriation of giant tortoises at centers such as the Galapaguera de Cerro Colorado; and the promotion of responsible tourism, with naturalist guides, quotas and strict rules. Only in that way will this 'living laboratory of evolution' that welcomed Darwin be able to go on amazing the generations to come.
