These two Islands show a very interesting contrast, since both are around the same age and just a few miles from each other. The first is small in size, almost barren and volcanic all around; the latter is larger, lush and green in the higher points. They are both on our schedule for the day and we have the opportunity to understand their process of erosion as well as the colonization of plants and animals. Bartolome Island displays the iconic landscape of the archipelago, while Santa Cruz is fertile and commercially active. Both are amazing stops on our expedition.
