Islas Galapagos and Puerto Ayora, gateway to a volcanic world
Published on 09/11/2026 at 22:17 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Islas Galapagos, known in English as the Galapagos Islands, stretches out as a volcanic archipelago in the eastern Pacific Ocean, with Puerto Ayora on Santa Cruz Island acting as its busiest town and main tourism hub. The islands lie around 1,000 km (620 mi) off the coast of mainland Ecuador, and were inscribed as a UNESCO World Heritage site in 1978, anchoring their reputation as a landscape where geology and evolution are written into the rock and the sea.
An equatorial archipelago shaped by volcanoes and currents
The Galapagos Islands sit close to the equator and rise from the floor of the eastern Pacific as an archipelago of volcanic islands formed over millennia by eruptions and tectonic activity. The group includes large and medium-sized islands alongside numerous smaller islets and rocky outcrops, all surrounded by one of the world’s substantial marine reserves that protects the waters around the land.The archipelago lies about 970 km off mainland Ecuador and sits at the meeting point of several ocean currents, which helps generate the range of marine environments found here.The islands form part of a protected national park and surrounding marine reserve that together cover a very large area.
The land area of Islas Galapagos is spread across islands of differing sizes, with some exceeding 10 km² and many much smaller fragments of lava and ash scattered around them. Much of this emergent land lies inside Galapagos National Park, created in 1959, leaving only a small proportion available for towns and villages.The World Heritage inscription in 1978, later extended in 2001 to include the marine reserve formally recognises the islands under criteria that highlight geological features, ecological processes, natural beauty and habitats for biodiversity.
Puerto Ayora: everyday life on Santa Cruz Island
Puerto Ayora stands on the southern shore of Santa Cruz Island in central Galapagos, facing Academy Bay and acting as the seat of Santa Cruz Canton within Ecuador. It is described as the largest town in the archipelago and the heart of its human population, a place where boats cluster in the bay while streets and low-rise buildings run back from the waterfront into the island.The town lies at a low elevation and serves as the main urban centre on Santa Cruz, with local services and small-scale commerce supporting residents and visitors.
Across Santa Cruz Island, a road connects the northern ferry crossing at the Itabaca Channel with Puerto Ayora, passing through the island’s highlands and smaller settlements before descending again towards Academy Bay.Puerto Ayora functions as the main tourism hub in the archipelago, and hosts facilities such as the headquarters of Galapagos National Park and the Charles Darwin Research Station. The waterfront mixes piers, moored vessels and shorelines where marine iguanas and sea birds can be seen alongside human activity.
Evolution, protection and the Galapagos landscape
The scientific and cultural significance of Islas Galapagos is rooted in its role in the development of evolutionary theory and in the high level of endemism among its species. Charles Darwin’s visit in 1835, aboard HMS Beagle, allowed him to observe wildlife and geology across several islands, and these observations later contributed to his ideas about evolution by natural selection.The archipelago contains numerous rare and endemic species on land and in the surrounding sea, helping to justify its status as a protected area of global importance.
Protection on land and sea has been extended over decades, creating a layered framework of conservation designations and management bodies. The Archipiélago de Colón–Galápagos Biosphere Reserve was recognised under UNESCO’s Man and the Biosphere Programme in 1984, and the islands are also listed under the Ramsar Convention for certain wetlands.The World Heritage site covers terrestrial and marine areas under the same overarching name, with terrestrial hectares forming almost all the land area of the archipelago and the marine reserve extending across the surrounding ocean. Within this framework, research institutions in Puerto Ayora and elsewhere monitor wildlife and human impact, reinforcing the link between the town and the wider landscape.
Visiting Islas Galapagos: what travellers from Western Europe should know
- Islas Galapagos lies in the Pacific Ocean west of mainland Ecuador, and most visits route through the Ecuadorian mainland before continuing by air to airports in the archipelago and onward by road and boat to Puerto Ayora on Santa Cruz Island.
- Puerto Ayora stands at low elevation beside Academy Bay, and moving around town involves paved streets and short inclines, while excursions on Santa Cruz and nearby islands may include sections on uneven volcanic ground or sandy coastal paths.
- The archipelago’s location near the equator and its spread across multiple islands means that conditions vary between coastal zones, uplands and open sea, and travellers encounter a mix of urban areas such as Puerto Ayora and more exposed natural terrain.
- The official language is Spanish and the currency is the US dollar, used daily in Puerto Ayora and across Islas Galapagos.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.
