Experience the extraordinary diversity of Isabela Island, beginning at the volcanic islets of Tintoreras. Clear, shallow waters surround these dark lava formations, creating a favorable habitat for reef sharks, marine iguanas, sea turtles, sea lions, and colorful fish. When conditions allow, explore the area by snorkeling before traveling inland toward Sierra Negra Volcano. Hike through changing vegetation and volcanic terrain to reach viewpoints overlooking one of the largest calderas in the Galapagos. The immense crater and surrounding landscape provide a striking example of the geological forces that formed Isabela. Later, visit the Arnaldo Tupiza Breeding Center, where native giant tortoises are protected through carefully managed breeding, care, and repatriation programs. Observe individuals of different ages while learning about the conservation work supporting their survival.
