Cueva de Zugarramurdi

Cueva de Zugarramurdi (Zugarramurdi Cave) is a large natural cave complex near the village of Zugarramurdi in northern Navarre, close to the French border and approximately 95 kilometres from Pamplona. The caves were formed by the stream Infernuko erreka — 'stream of hell' in Basque — which carved a 120-metre-long tunnel through the limestone over millennia. The cave is most famous in Basque cultural history for its association with witchcraft: it was the reputed site of akelarre (witches' sabbath) gatherings, and in 1609 the Spanish Inquisition conducted one of its largest witch trials here, resulting in the burning of eleven people in Logroño. This history — part folklore, part historical tragedy — is explained in depth in the adjacent Museo de las Brujas (Museum of Witches), where exhibitions cover Basque witch mythology, the Inquisition trials, and the social context of 17th-century persecution. The cave itself is accessible on a self-guided walk through an illuminated tunnel, with the central chamber opening to the sky and the underground stream still flowing through. The annual Aquelarre festival in late June brings theatrical fire performances and Basque folklore events to the cave setting. The combined caves-plus-museum admission allows free movement between both sites. The village of Zugarramurdi has traditional restaurants serving Navarrese and Basque cuisine, making a meal here a natural addition to the visit.
