Isabela Island holds the distinction of being both the youngest and largest island in the Galapagos archipelago. Stretching 120 kilometers in length and covering 1,771 square miles, it’s larger than all the other islands combined. Located in the western part of the Galapagos, Isabela is a geological marvel.
The island was formed by the merging of six shield volcanoes: Alcedo, Cerro Azul, Darwin, Ecuador, Sierra Negra, and Wolf. Each of these volcanoes originally rose independently from the ocean floor. Over time, repeated eruptions caused their lava flows to merge, creating the single, expansive island we see today.
Isabela Island lies close to the Galapagos hotspot, making it one of the most volcanically active regions on Earth. All six of its volcanoes are still active, with eruptions occurring periodically. This ongoing volcanic activity makes Isabela a captivating destination for those eager to witness the unstoppable, natural forces that forge our planet.
Isabela Island is home to a wide range of natural Galapagos habitats, each with its own unique characteristics.
Isabela Island’s diverse habitats showcase the incredible adaptability of life in the Galapagos, from barren lava fields to lush highlands and vibrant coastal ecosystems. Each area tells a story of resilience and natural beauty.
Isabela Island in the Galapagos is famous for its stunning wildlife and volcanic landscapes, but it also holds a fascinating human history. The island’s name has changed over time. In 1684, explorer Ambrose Cowley mapped the Galapagos archipelago and named the largest island Albermarle, in honor of George Monck, the 1st Duke of Albermarle, a key figure in the English Civil War and monarchy restoration.
Later, Ecuador renamed it Isabela to pay tribute to Queen Isabella I of Castile, the first queen to rule over a united Spain. The earliest visitors to Isabela were pirates and whalers, who used the island as a refuge to restock supplies and avoid Spanish authorities. Tagus Cove was a favored landing spot, where they gathered giant tortoises for food.
Permanent settlement on Isabela began in 1897 when Ecuadorian Antonio Gil established Puerto Villamil along the coast. The town initially functioned as a lime house, where coral was burned for construction material. Meanwhile, the highland settlement of Santa Tomas became a hub for sulfur mining, coffee plantations, and livestock farming. Gil also hunted giant tortoises for oil, which was used to power street lamps in Ecuador. His efforts led to a thriving community, with the island’s population growing from around 200 in the early 1900s to over 2,000 today. Remnants of this history can still be seen in Puerto Villamil’s small cemetery, where the graves of early settlers remain.
In 1946, Isabela Island became the site of a penal colony, where 300 convicts from the mainland were sent to endure grueling forced labor under the scorching equatorial sun. One of the most haunting remnants of this era is the Wall of Tears—an imposing structure built from black lava rocks, standing in the middle of nowhere, serving as a stark reminder of their suffering.In recent years, Isabela has embraced modern infrastructure to support its growing tourism industry. The development of Puerto Villamil airport has facilitated intra-island flights, making the island more accessible to visitors. Today, most of Isabela’s 2,200 residents rely on tourism, fishing, and farming for their livelihood, blending the island’s rich history with its vibrant present.
Isabela Island is home to the largest population of wild giant tortoises in the Galapagos, surpassing all other islands combined. Even more fascinating, it hosts the greatest variety of tortoise subspecies, making it a must-visit location for anyone inspired to learn about these legendary creatures. Across the Galapagos, most of the 15 tortoise species are confined to specific islands—such as Española, Fernandina, Floreana, Pinta, Pinzón, San Cristobal, Santa Cruz, Santa Fe, and Santiago. This distribution aligns with Darwin’s theory of evolution, as each population has uniquely adapted to the environmental conditions and food sources of its respective island.
What sets Isabela Island apart ? Its remarkable diversity of tortoise species. The island was formed by the fusion of six shield volcanoes, creating a landscape of towering volcanic peaks separated by rugged lava fields. These jagged lava formations act as natural barriers, preventing tortoises from migrating between different areas. As a result, the isolated populations around each volcano evolved independently, much like species separated by ocean barriers, leading to the development of five distinct subspecies. The five giant tortoise species found on Isabela inhabit the areas surrounding the Wolf, Darwin, Alcedo, Cerro Azul, and Sierra Negra volcanoes. Since most of these volcanoes are not accessible to visitors, the best place to observe these magnificent creatures in their natural habitat is a highland ranch on the slopes of Sierra Negra. For those interested in conservation efforts, the Arnoldo Tupiza Breeding Center provides an opportunity to see tortoises from the southern populations being raised in captivity before being released to help ensure the survival of these endangered species.
Reaching Isabela Island is relatively straightforward, especially if you’re visiting Puerto Villamil and the southeastern attractions as part of a Galapagos land-based tour. However, exploring Isabela’s remote western coast requires a Galapagos cruise, as it is too far for day trips. Cruises that include western Isabela often also visit Fernandina Island, making for an incredible and highly recommended itinerary.
