Isabela Island is the largest island in the Galapagos archipelago. Five huge shield volcanoes make up the island’s backbone. Starting from the north, the volcanoes are Wolf, Darwin, Alcedo, Sierra Negra, and Cerro Azul. These massive volcanoes are all active. Every three years or so, one of the volcanoes erupts.

National Geographic Endeavour II
Genovesa Island
The last full day of our expedition brings us to Genovesa Island, our northern most site in the archipelago. At our anchorage within a massive, submerged caldera, we were surrounded by incredible avian wildlife. After a dry landing at Prince Phillip’s Steps, we explored the outer cliffs where storm petrels nest along the lava fields, and short-eared owls actively hunt them during the day. The rough volcanic background with birds nesting upon the grey palo santo trees makes for dramatic scenery. An alternative landing takes us to Darwin Bay, where a short walk occurs with a density of life incomparable to other islands in the archipelago. Great frigatebirds soar overhead searching for a feeding opportunity. Red-footed boobies nest among the mangroves and saltbush while Swallow-tailed gulls care for their chicks along the coralline coast. This is an island setting in a world among itself.
