Tesoros escondidos bajo tierra
Las entrañas de Bizkaia cobijan todo tipo de secretos: cuevas laberínticas, huellas pintadas por nuestros ancestros y rastro de mitos.
Los trabajos en una cantera cercana descubrieron la cueva de Pozalagua, una cavidad de 125 metros que alberga la mayor concentración de estalactitas excéntricas del mundo. Una creación espectacular de la naturaleza que puedes visitar en el Valle de Karrantza.
Otra cueva de enorme interés es Santimamiñe, en Kortezubi, con pinturas rupestres en sus paredes (osos pardos, bisontes o ciervos,...) y una gran riqueza geológica gracias a sus bellas columnas de estalactitas y estalagmitas.
Mientras, en el Parque Natural de Urkiola, la Cueva de Baltzola presenta un escenario mágico envuelto en leyendas. Te invitamos a perderte por sus galerías, hogar de lamias y gentiles, entre otros personajes de la mitología vasca.
It was not until the early twentieth century that the Santimamiñe Cave and its Palaeolithic rock paintings were found. A few decades later, workers at a quarry discovered Pozalagua, a treasure hidden under the ground in Armañón Nature Park, in the region of Las Encartaciones.
Santimamiñe is the main prehistoric site in Bizkaia. Located in Kortezubi, it contained artefacts and paintings. These remains had been there for more than 13.000 years ago, since the Magdalenian period of the Upper Palaeolithic. The cave has been listed as a Unesco World Heritage Site since 2008. Inside the tunnel are black charcoal paintings that represent animals: 32 bison, 7 goats, 6 horses, a deer and a bear.
Since 2006, Santimamiñe has been closed to the public. However, you can still go on a 90-minute tour and watch a 3D film of the cave, rock paintings included, at the visitor centre, housed in the nearby shrine of San Mamés.
Open to visitors since 1991, Pozalagua is a cave located in Peñas de Ranero, in Karrantza. Named in Repsol Guide as Best Corner of 2013, this cave was found by chance in 1957 after an explosion in a nearby quarry. It is a spectacular underground treasure that had been hidden for thousands of years. Curtains, stalagmites and stalactites have grown forming peculiar and beautiful shapes. What makes Pozalagua unique is the huge concentration of eccentric stalactites that, defying the laws of gravity, branch in different directions.
The 50-min tour takes visitors on a walkway flanked by stalactites, stalagmites and curtains. You will pass through a dry lake bed to reach the Versailles chamber, where you will find a huge concentration of eccentric stalactites. The tour ends on a viewpoint affording views of the chamber at large.
Routes
This is a kid-friendly, two-hour walk to the caves of Baltzola and the Jentilzubi Bridge. The caves are in Dima, in the heart of the Arratia Valley and Urkiola Nature Park. Park your car in the small parking area in the Baltzola neighbourhood in Dima, close to the bridge and the caves, where mythological creatures live.
In a pleasant two-hour walk, you can admire the caves of Baltzola and the Jentilzubi Bridge. According to the legend, diferent mythological creatures live there
Bring a flashlight with you; you will need it to explore these amazing caves that are frequently visited by spelunkers and climbers. According to legend, the caverns were inhabited by lamias, female mythological creatures that are half human and half duck, with a fish caudal tail and claws.
They say that Sugoi, goddess Mari's husband (a genie that morphs into a snake), and their son, Mikelatz, live in the caves too. On the way, you will see Jentilzubi, a natural bridge that is said to have been built by the Jentil, extremely strong legendary creatures, to pass from mountain to mountain while hiding from Christians. Climb up the Jentilzubi Bridge to watch Abrigo de Axlor, the oldest archaeological site in Bizkaia, discovered by Joxe Migel Barandiaran. A metal fence protects the remains of humans from the Middle Palaeolithic, the oldest in Bizkaia (150,000-40,000 BC).
