Isabela Island has five active shield volcanoes; each one has its own beauty and interest. Wolf Volcano, which stands at the highest point in the Galapagos has its own population of land iguanas, as well as a new species known as the pink iguana, because it lacks pigmentation on its scales. Interestingly, each of these giant volcanoes have their own kind of tortoises. This morning we had the privilege to observe the ones from Alcedo Volcano, home to the largest giant tortoises of the eleven found in the Galapagos.
