Why visit the Western Galápagos

If the Eastern Galápagos is where the islands first won their reputation, the Western Galápagos is where nature feels at its most untamed. Encompassing Isabela, Fernandina, Santiago and Rábida, this is the youngest part of the archipelago, where vast shield volcanoes continue to shape the landscape and wildlife has evolved in extraordinary isolation.

Towering lava cliffs, smoking volcanoes and untouched black lava fields create a dramatic backdrop for some of the richest wildlife encounters in the Galápagos. This is one of the few places on Earth where you can watch Galápagos penguins dart through tropical waters, observe flightless cormorants drying their stunted wings and encounter marine iguanas gathered in their thousands along the shoreline.

Beneath the surface, nutrient-rich currents support exceptional marine life. Sea turtles, reef sharks, eagle rays and playful sea lions are common companions while snorkelling, while dolphins and whales are regular seasonal visitors offshore.

Reaching the Western Galápagos requires a longer expedition than the eastern islands, but those who make the journey are rewarded with quieter visitor sites, spectacular volcanic scenery and some of the archipelago’s most remarkable endemic wildlife. For many experienced travellers, this is the Galápagos at its very best.

Highlights of the Western Galápagos Islands

  • See the world’s only tropical penguin – The western coastline of Isabela is one of the most reliable places to watch Galápagos penguins hunting among lava cliffs, often just metres from your Zodiac.
  • Encounter flightless cormorants – Fernandina is one of the only places where these extraordinary birds can be seen nesting, having evolved to abandon flight in favour of becoming exceptional underwater hunters.
  • Explore one of the world’s youngest volcanic landscapes – Walk across pristine lava flows on Fernandina and western Isabela, where eruptions within living memory continue to reshape the islands.
  • Snorkel in nutrient-rich waters – The cool Cromwell Current brings an astonishing abundance of marine life, with sea turtles, penguins, sea lions, reef sharks and eagle rays all commonly encountered.
  • Visit Fernandina, the Galápagos’ most pristine island – With no introduced mammals and virtually no permanent human impact, Fernandina offers one of the closest glimpses of how the islands appeared when Darwin first arrived.
  • Witness volcanic giants – Sail beneath the immense flanks of Sierra Negra and Cerro Azul on Isabela, among the largest active shield volcanoes anywhere on Earth.
No humans

Fernandina has never been successfully colonised by humans. Its isolation and frequent volcanic eruptions have protected it from many of the introduced species that affected other Galápagos islands, making it one of the world’s most pristine island ecosystems.

Equatorial penguins

Galápagos penguins survive on the Equator because of cold ocean currents. The nutrient-rich Cromwell Current cools the western islands sufficiently for the world’s rarest penguin to thrive in a tropical climate.

Good to know

Getting to the Western Islands

The Western Galápagos cannot realistically be explored on a day trip. Most visitors experience the region aboard expedition cruises of at least five to eight nights, departing from either Baltra or San Cristóbal.

Longer itineraries spend several days exploring the western islands, allowing access to remote visitor sites such as Fernandina, Tagus Cove, Elizabeth Bay, Punta Vicente Roca and Urbina Bay.

Land-based visitors can stay on Isabela Island; reaching the archipelago’s spectacular western coastline is only possible by expedition vessel.

Wildlife that is endemic to the Western Islands

These species and subspecies occur naturally only in the Western Islands.

  • Galápagos penguin (Spheniscus mendiculus) – The world’s only penguin to breed naturally on the Equator, found primarily on western Isabela and Fernandina.
  • Flightless cormorant (Nannopterum harrisi) – Restricted to Fernandina and the west coast of Isabela, where its ancestors evolved to abandon flight.
  • Fernandina marine iguana (Amblyrhynchus cristatus phillipsi) – The largest marine iguana subspecies, found only on Fernandina Island.
  • Pink land iguana (Conolophus marthae) – One of the world’s rarest reptiles, confined to the northern slopes of Wolf Volcano on Isabela.
  • Fernandina racer (Pseudalsophis biserialis) – Endemic to Fernandina Island and best known for its dramatic pursuit of newly hatched marine iguanas, immortalised in Sir David Attenborough’s Planet Earth II.
  • Isabela giant tortoise complex (Chelonoidis spp.) – Several distinct giant tortoise species evolved independently on Isabela’s separate volcanoes, each confined to a different part of the island.

OUR FAVOURITE TIME TO VISIT

The Western Galápagos is at its finest from June to October, when the nutrient-rich Cromwell Current transforms the surrounding waters into one of the richest marine ecosystems in the Pacific. This is the best time to see Galápagos penguins, flightless cormorants and large concentrations of marine life, while cooler temperatures make hiking across the volcanic landscapes particularly enjoyable.
