Isabela Island is the largest and most active island in the Galapagos. Our journey took us deep into the heart of the Sierra Negra Volcano. We hiked across the vast caldera’s lava fields and felt the air grow thick with the scent of sulfur and mystery. Isabela is an island of contrasts where every step tells a story. This was not just a visit, it was a voyage in the wild Galapagos!
