Unlike many tourist attractions, it is difficult to tell that there has been any human intervention in the cave structure. The main work has gone into an awesome lighting system which highlights the walls of the cave extraordinarily well.

The Cuevas de los Verdes was an excellent place to hide for the local people, going as far back as the Guanches who were an aboriginal people who used to inhabit the Canary Islands.

In fact there is actually a chamber within the tunnel which is known as 'The Refuge', because it was so often used for shelter.
