This large group of lava tubes will leave you with some unforgettable memories.
An extraordinary underground experience near Icod de los Vinos.
Get ready for one of Tenerife's more dramatic attractions, located up in its northwest near the town of Icod de los Vinos. Here's where you'll find Europe's largest complex of underground lava tubes, some 20 kilometres' (12 miles') worth. Just a portion is open to the public, via guided tour, but it's still an unforgettable experience, thanks to its spectacular sights and geological/archaeological richness. Major finds of aboriginal remains have been made here and these caverns have also been a key centre for volcanic studies.
