Pozalagua Cave

View on map

The Pozalagua cave is a marvel of nature, a veritable underground cathedral. It boasts the world's highest concentration of eccentric stalactites, formations that grow defying gravity and create a dazzling mosaic.

Located in the Karrantza Valley, within the Armañón Natural Park, the Pozalagua Cave is a marvel of nature. It boasts the world's highest concentration of eccentric stalactites , formations that grow defying gravity and create a dazzling mosaic. It was chosen as the Best Spot by the Repsol Guide in 2013.

The proliferation of stalactites and formations of all kinds makes Pozalagua a hypnotic place, a veritable underground cathedral . More than sixty years have passed since its discovery, and the cave continues to fascinate those who return to explore it.

The underground complex is spectacular. The tour takes you among columns, flowstones, and a dried-up lake, from which tens of thousands of eccentric stalactites sprout haphazardly, seemingly forming an endless coral reef—a forest in the Earth's depths. The route culminates at a viewpoint from which you can contemplate the grandeur and beauty of this subterranean corner in all its splendor. The temperature inside remains around 13°C year-round, so it's advisable to wear appropriate clothing.

Opposite the grotto rises the Pozalagua amphitheater , carved from the old dolomite quarry, with a capacity for 2,000 spectators. It is a regular venue for concerts, operas, and theatrical performances thanks to its perfect scale and acoustics.
