Española Island is the oldest of the Galapagos Islands, as it sits on the southeastern end of the archipelago. The islands are of volcanic origin and are formed because of the activity of what geologists call a hot spot. As the Nazca Plate slides to the southeast over the volcano-producing area, new islands develop. This means that the islands towards the northwest are the youngest, and the ones on the opposite end are the oldest.
National Geographic Endeavour II
Our day started with a very relaxing hike in the morning at Dragon Hill on Santa Cruz Island. We had the chance to spot a few land iguanas on the path and close to their burrows. We also had the opportunity to take a Zodiac ride around the shore of that area and got to see a few blue-footed boobies looking for fish in the ocean. Later, we snorkeled off Guy Fawkes Islet and saw loads of reef fish.
