Named after Queen Isabel, this island is the largest in the Galapagos Archipelago. It is made up of volcanos, which are still very active, erupting as recently as last year. Urbina Bay is our landing site, with a black sand beach where turtles annually lay their eggs. The area is vast and heavily vegetated due to its rich volcanic soil, producing many sources of food, safety, and nesting sites for birds. It also creates areas of shade and nesting sites for reptiles like giant tortoises and land iguanas. During our outing, we saw a variety of land birds, as well as a several tortoises and land iguanas.
