Los Argüellos is an example of a Cantabrian mountain ecosystem, in which the scant resources available have been put to wise use by the local population for many centuries, shaping a unique landscape.

Hiking is a great way of enjoying and conserving its natural and ethnographic values which are practically unexploited, and there is much to explore and discover. Valporquero Cave is a fine example of the underground formations that are typical of karst landforms.
