Isabela Island is the largest island in Ecuador's Galápagos archipelago, lying about 1,000 km off the country's Pacific coast. A spectacular volcanic and wildlife destination, it is home to five active volcanoes, extensive lava landscapes, wetlands and rich coastal ecosystems. Travellers can hike around the vast caldera of Sierra Negra, explore lava formations at Volcán Chico and encounter giant tortoises, flamingos, marine iguanas and other distinctive Galápagos wildlife. Along the coast, snorkelling at Tintoreras offers encounters with sea lions, sea turtles, rays and marine iguanas, while boat trips can reach wildlife-rich sites such as Elizabeth Bay and Punta Vicente Roca. Puerto Villamil provides a laid-back base for exploring the island's beaches, lagoons and nature trails, combining remarkable wildlife encounters with dramatic volcanic landscapes.
