Española Island is one the more ancient Galapagos Islands and deemed to be over 4 million years old. It's origin is steeped in a volcanic history, that has dominated the formation of the region and neighbouring islands. It started as a classic shield volcano, created from a single caldera in the centre of the island. But over the course of tectonic time, it moved away from the hot zone and eventually became extinct. Today, time and erosion has made its mark on Española, making it one of the flattest and lowest islands left in the archipelago. Endemic wildlife flourishes with the lava lizards and waved albatross, along with the Española mockingbird.
