The cave was formally declared a site of historical importance following the 1610 auto-da-fé where the Inquisition condemned 53 people.
Local folklore suggests the cave served as a meeting place for nocturnal gatherings involving rituals and dance, known in the Basque language as akelarre.
The name 'akelarre' derives from the Basque 'aker' (he-goat) and 'larre' (meadow), referring to the meadow where the cave is situated.
The Olabidea stream, locally known as the 'Hell's Ravine' (Infernuko Erreka), flows directly through the main chamber.
Unlike traditional karst caves with stalactites and stalagmites, the geological formation here is primarily a tunnel created by erosion.
The trial of the Zugarramurdi witches is considered the most significant and largest in the history of the Spanish Inquisition.
Cuevas de Zugarramurdi is a large, natural limestone tunnel carved by the Olabidea stream in the Pyrenees foothills of Navarre, Spain. The site is globally recognized as the historical center of the 1610 Basque witch trials, where the Spanish Inquisition investigated local folklore gatherings known as akelarres. The cave spans approximately 120 meters in length and reaches a height of 12 meters in its main chamber. Unlike typical subterranean caves, this structure is a tunnel formation featuring open ends that allow significant natural light to penetrate the interior. Visitors walk along a clearly marked path that follows the stream through the cavern. The site includes educational signage detailing the sociological history of the 17th-century trials and the subsequent local impact. It remains a focal point for understanding the intersection of regional mythology and ecclesiastical history.

Wear sturdy footwear with good grip, as the ground inside the cave can be slippery and uneven due to the stream.
Visit the accompanying Witchcraft Museum in the village center to fully understand the historical context of the cave.
Bring a light jacket, as the ambient temperature inside the tunnel is noticeably cooler than the forest exterior.
Do not attempt to traverse the stream banks outside of the designated paths, as the terrain is ecologically fragile and slippery.
The site is open year-round but may close temporarily during extreme weather events; check local visitor center status for seasonal variations.
Maintain silence to respect the site's historical significance and preserve the natural atmosphere; do not climb on the limestone walls.
