The Galápagos Islands sit on the Nazca tectonic plate whose eastern boundary is slowly subducting underneath the South American plate. Therefore, the oldest islands are located in the east and south of the archipelago; the western islands—closer to the hotspot—remain volcanically active and are the youngest. Española is now the remains of what was once a shield volcano, harboring an amazing array of native species. Like its neighboring islands, San Cristobal and Floreana, Española presents a high rate of endemism compared to the rest of the Galápagos.

National Geographic Endeavour II
Isabela Island
Another action-packed and unforgettable day unfolded in the wild western reaches of the Galápagos Islands. We began with a gentle morning stretch, followed by an early hike along Urbina Bay — a surreal landscape born from the uplift of the seafloor. Towering shield volcanoes loomed around us, creating a dramatic backdrop. Golden land iguanas basked in the morning sun, while Darwin’s finches, mockingbirds, and vibrant yellow warblers flitted through the dry brush, offering glimpses of the archipelago’s famous evolutionary story. Our young explorers took to the helm this morning, learning to drive Zodiacs with confidence and a healthy dose of laughter. On board, we delved into the fascinating human history of the archipelago, unravelling stories of pirates, pioneers, and scientists who once roamed these shores. After a scrumptious Ecuadorian lunch, our afternoon was brimming with adventure: kayaking through the impressive geology and calm waters of Tagus Cove and snorkeling among unique sea life. The real stars of the afternoon? The lightning-fast, tuxedoed Galápagos penguins, zipping around us in the water, leaving us in awe of their agility.As the day ended, half of our group hiked the trail above Tagus Cove, while others enjoyed a peaceful panga ride around Darwin Volcano.
