Deboyo Cave

Deboyo Cave is located in the Biosphere Reserve of the Redes Natural Park in the council of Caso, near the village of Les Yanes.

It is a cave of karstic origin through which the river Nalón flows at the beginning near the village of Les Yanes (near Campo de Caso) with a length of 200 metres. Its interest is based on the fact that it is where most of the bats in the reserve nest, such as the Mediterranean horseshoe bat, the river bank bat and, to a lesser extent, the big horseshoe bat, the dwarf bat and the cave bat.
