From the car park of the Hagerbach Test Gallery, equipped with lanterns, you walk about 90 metres up the forest path to the enchanting Poli.
After this easy effort a first reward awaits you. A mulled wine aperitif with Maja Anderegg and her Geissenbuebe and Eselmeitli (geissebuebe.ch) in the Geissenstall with delicious snacks.
Afterwards, the circular trail, now accompanied by the goats*, takes you down to the mysterious second entrance of the Hagerbach experimental mine. In the past, the legendary secret army P26 used this entrance to enter the tunnel system unseen.
Here we say goodbye to our newly won goat friends and with the lanterns we now walk through the darkness of the mystical tunnel to another highlight of the evening: The "Big Bang 4d" blasting demonstration. A massive and impressive lay-on blasting with projection support.
Afterwards, we take the Stollenzügli for a well-deserved fondue dinner in our restaurant inside the mountain. Time to drink a toast to the experience.
