Cabo de Gata constitutes a small exposed part of an extensive volcanic chain, between 6 and 15 million years old. It is located between Spain and North Africa and currently appears submerged almost in its entirety, emerging only in Cabo de Gata and on Alboran Island.
This peculiar geological configuration has enabled the formation of one of the most unique fossil volcanic complexes in Europe. It is a geological landscape of capricious shapes with a particular color, in which red, ochre and black tones predominate, and which shows a wide range of volcanic rocks with different types of composition, textures and structures. Domes, volcanic lava flows, chimneys, boilers and pyroclastic rocks are found in all their splendor in Cabo de Gata.
It is worth mentioning the following examples of volcanism that we can find in Cabo de Gata:
- Volcanic craters: the best example is the current Rodalquilar Valley.
- Fossilized lava tongues: the best example is Monsul Cove.
- Volcanic domes: the best example is Mesa Roldan.
- Volcanic chimneys: the most beautiful examples are found in the Sirens Reef.
