Today we explored the magnificent island of Isabela. This island is the biggest of the archipelago and one of the most beautiful. The reason may be that it hosts the largest population of Galapagos penguins, or because its perfectly blue waters host so many sea turtles …. Whatever the reason, we cannot resist Isabela’s charm.
National Geographic Endeavour II
Española is the oldest of the Galapagos Islands. It sits on the southeastern end of the archipelago. The Galapagos are volcanic islands that formed over a geological “hot spot.” As the tectonic Nazca Plate slides to the southeast over the volcano-producing area, new islands emerge. This means that the islands towards the northwest are the youngest and the ones on the opposite end are the oldest.
