The Charles Darwin Research Station
Founded in 1959 and operated by the Charles Darwin Foundation, the research station sits on the eastern edge of Puerto Ayora — a five-minute walk from the main pier along a shaded coastal trail. An admission fee is required for the guided circuit (currently USD 10 for international visitors). Open daily. It is simultaneously the most-visited single attraction in the Galápagos and an active scientific institution driving the archipelago’s conservation agenda.
The Fausto Llerena Tortoise Breeding Center is the headline draw. Open-air pens allow visitors to walk among hatchlings, juveniles, and adult breeders representing several giant tortoises subspecies — including individuals from islands where wild populations once collapsed. The most famous resident in living memory: Diego, a male Española tortoise repatriated from the San Diego Zoo in 1977, credited with fathering a large share of the recovered Española population. He was returned to the wild on Española in 2020 after the program was declared a success.
Adjacent displays honor Lonesome George — the last Pinta Island tortoise, who died on June 24, 2012, and whose preserved body is now on permanent display in a climate-controlled hall. The station also covers Darwin’s finches, marine iguanas, invasive species control, and tortoise reintroduction genetics.
Galápagos giant tortoise populations have risen from roughly 8,000 individuals in the 1970s to approximately 30,000 today — a recovery driven almost entirely by captive breeding and repatriation programs originating at this station. (Source: Galápagos National Park, PNG, 2022)
