Equipped with helmets, headlamps and a map, the teams made their way through the tunnel systems to track down various stations that could only be solved with a lot of creativity, teamwork and communication. Individual challenges included finding your way around the mountain in complete darkness, crossing a suspension bridge with headlights and various arithmetic and logic tasks.
The adventure was finally rounded with a joint lunch on the sun terrace of the restaurant „Bergmanns Schänke”.
