Overview
- Three young men from North Rhine‑Westphalia entered the restricted Mendig lava‑tunnel system without permission and became disoriented before placing an emergency call, which triggered the rescue operation on Wednesday.
- Fire brigade, police and emergency medical teams carried out the search with about 13 firefighters involved and received maps from an Environmental Ministry expert to navigate the maze of shafts.
- Rescuers narrowed the men's location by calling into multiple access shafts and using sound propagation from sirens to guide the extraction.
- The three were found lightly hypothermic but uninjured, treated at the surface, and now face a criminal trespass report while the municipality says they will likely be billed roughly €1,000 for the operation.
- The Mendig lava‑keller network lies about 32 metres below ground across roughly three square kilometres at a constant near‑7°C and may be entered only on guided tours, officials warned that unauthorized access endangers visitors and rescuers.
