Caving in the Lamiñetako Caves, Basque Country

Context Caving at the Lamiñetako Caves takes place in a subterranean system located between Lekeitio and Berriatua in Bizkaia. This area is known for its striking geological features such as stalactites and stalagmites, and features a dramatic five-meter deep entrance known as a 'simá'—a vertical shaft that leads into the cave’s network of tunnels. The journey winds through a remote rural landscape where the wind carries scents of thyme and damp earth.

The Experience Over 3–4 hours, you descend into the shaft using technical gear and progress through tight passages, navigating climbs and low crawls. Constant cool temperatures and the echo of underground water accompany your journey. Your expert guide shares insights into the geology of the caves and tells local legends about the lamias—mythical female spirits from Basque folklore believed to inhabit these deep, hidden spaces.

For Whom This caving experience is suitable for people in good physical condition and comfortable with confined spaces. It’s ideal for families with children over 8 years old, adventure-seeking friends, and travelers interested in nature and regional culture. Not recommended for those with limited mobility or who experience claustrophobia.

Local Context The lamias are part of the Basque cultural imagination, and their presence in the caves adds deep meaning to the adventure. The surrounding rural area preserves traditional practices like transhumance (seasonal animal herding) and offers a distinctive landscape that enhances the caving experience.
