Cueva del Viento | Tenerife

The Cueva del Viento ("Cave of the Wind") is a vast and fascinating underground lava tube located in the municipality of Icod de los Vinos in northern Tenerife. It is one of the largest volcanic tunnels in the world, offering a unique opportunity to explore Tenerife’s volcanic heritage through its intricate network of caves, galleries, and geological formations.

Geological Significance

Formation

• The lava tube was formed around 27,000 years ago during an eruption from the Pico Viejo volcano, located near Mount Teide.
• As the surface lava solidified, molten lava continued to flow beneath, carving out tunnels and chambers in the rock.

Size and Scope

• The cave system spans over 18 kilometers (11 miles), making it the longest lava tube in Europe and one of the largest in the world, surpassed only by systems in Hawaii.
• The network includes three levels of interconnected passages, which are rare for lava tubes.

Geological Features

• Visitors can observe lava stalactites, lava lakes, and intricate rock formations.
• The cave also contains volcanic fossils and imprints of tree trunks burned by lava flows.
