The Cueva del Llano is one of the very few geological systems that have remained visible in Fuerteventura. This is due in part to the islands greater age and the extent of the erosion as a consequence. The Cueva del Llano is a volcanic tube and is unique among the lava tubes of the Canary Islands because of its age and that it has functioned for many thousands of years as a drain of a small basin, the Lomo del Jable. Successive flows of water into its interior have filled the cavity with sediments and the fossilised remains of living creatures. From these sediments it appears to show that Fuerteventura had two wet periods alternated with other dry periods. The wet periods are shown by the abundance of species associated with humidity such as snails. Fossils from the first period have been dated at 15,000 years and about 7,500 years for the second. The subterranean environment is a poor ecosystem where humidity is high and darkness absolute. The creatures that inhabit this medium are in the majority insects and arachnids (spiders) adapted to permanently living in the dark.

The cave is in complete darkness and safety helmets with lights are the only source of illumination due to the very fragile environment remaining undisturbed. Sensible footwear is recommended although the cave is largely level once inside.
Have an enjoyable and instructive visit.
