Isabela Island, the largest island in the Galapagos, offers breathtaking volcanic landscapes, unique wildlife, rich history, and thrilling adventures such as hiking, snorkeling, and diving.
As the largest island in the Galapagos archipelago, Isabela Island boasts extraordinary natural landscapes, abundant unique wildlife, and a fascinating historical legacy.
This island is not just a tourist destination but also a living laboratory that once inspired Charles Darwin in formulating his theory of evolution.
A Volcanic Wonder: The Formation of Isabela Island
Isabela Island is known for its volcanic activity, having been formed by the merging of six active volcanoes. To this day, Wolf Volcano, one of the tallest volcanoes in the Galapagos, continues to show signs of activity.
Spanning an area of 4,640 km², Isabela Island is not only twice the size of Santa Cruz Island but also larger than all the other Galapagos islands combined.

The Historical Legacy of Isabela Island
Isabela Island is not only renowned for its natural beauty but also for its dynamic historical background. The island was first visited by Charles Darwin in 1835, where he observed its rich biodiversity, which later became the foundation of the Theory of Evolution.
Additionally, the island has a colonial history and settlements that led to the formation of Puerto Villamil, the main town on the southern coast, as well as Santo Thomas in the highlands.
However, Isabela also has a dark past, especially between 1945 and 1959, when it was used as a penal colony.
One of the most haunting remnants of this period is the Wall of Tears, a massive stone structure built by prisoners under harsh and brutal conditions. Many lives were lost during its construction, making it a somber reminder of the island’s grim past.
