Guide of the Azores – What to visit, what to eat and where sleep

Geology of the Azores

The volcanic origin of the Azores and their evolution over millions of years have transformed the archipelago into a true open-air natural museum, filled with unique and fascinating geological phenomena.

The rounded shapes of volcanic calderas, often filled with crystal-clear lakes, contrast with lava caves and long lava tubes formed during ancient eruptions. The black surfaces of solidified lava flows, eruptive materials ranging from shiny obsidian to light and porous pumice stone, and the steam rising from fumaroles reveal the powerful forces shaping the Earth beneath the islands.

Exploring the geology of the Azores means discovering the planet’s history through dramatic landscapes, where nature continues to shape the territory and amaze visitors.
