Located to the west end of Bizkaia, in the border with Cantabria, the Armañon Natural Park or Ranero constitutes a relevant mountain massive in the landscape of Las Encartaciones. It extends between the cliffs of the rivers Carranza and Agüera, in a series of hills and mountain terrains covering a surface of 2,996 hectares. The highest point of this placed on the summit of Armanón (854 m.), although there are other outstanding tops, such as Ranero (737 m.), Surbias (638 m.) and Los Jorrios (837 m).
The nature of the massif is essentially calcareous and results in a surface landscape with amazing landforms, in which the karst shapes are common, with karrens, sinkholes, crevices... Moreover, it forms a subterranean landscape with more than 200 caves and chasms that have been catalogued and that have a remarkable geological, paleontological, speleological and biological value. Thus, the Pozalagua cave is an obligatory stop. It was discovered in 1957 and its importance rests in an exceptional phenomenon resulting in eccentric stalactites, that instead of growing downwards they grow in any direction. The cave is situated 2 km from the Ranero neighbourhood in the Karrantza Harana/Valle de Carranza and fitted out for tourist tours. Likewise, we must mention the Torca del Carlista, one of the biggest cavities in Europe, which is more than 400 metres long, 250 metres wide and 90 metres high.

If you do not know the Las Encartaciones district, you are truly missing out on something... a charted place, or rather an enchanted place, with its bridges, palaces, tower-houses which magically whisk us back to the past, on occasions a bloody past with fights between rival groups, the Oñacinos and the Gamboinos... Come in and discover a district you have inside you.
