A blasting demonstration as the grand finale of your visit to Hagerbach! Feeling the shockwave is a real highlight and makes every visit to the tunnel a special experience. The “Big Bang 4D” live blasting demo takes this experience to the next level. A film explaining the blasting process is projected onto a large rock face deep inside the mountain. As the countdown begins, the tension among the guests rises—everyone eagerly awaits the blast. Then the moment arrives: Ten detonations go off, the shockwave is palpable, and the projected rock face appears to collapse.

A very special evening awaits you. Equipped with lanterns, the trail leads along the forest path up to the idyllic Poli, where the first surprise awaits: a mulled wine reception with Maja Anderegg and her young goat herders and donkey girls in the goat barn, accompanied by delicious snacks. Afterward, we’ll take the loop trail—now accompanied by the goats—on a leisurely descent to the mysterious second entrance of the Hagerbach Experimental Tunnel. This entrance was once used by the legendary secret army P26 to enter the tunnel system unnoticed. There, we say goodbye to our new goat friends, and with our lanterns, we continue through the darkness of the mystical tunnel. Another highlight of the evening awaits us there: the “Big Bang 4D” blasting demonstration—an impressive and powerful trailer blasting with projection support. Finally, the mine train will comfortably take you to our restaurant deep inside the mountain for a well-deserved fondue feast. Time to raise a toast together to the adventure! An experience for 15 to 60 people Bookable from mid-October through March

Ich feierte ein tolles Geburtstagsfest im Versuchsstollen Hagerbach. Von der Planung, Organisation, dem Catering und der Location waren meine Gäste und ich begeistert! Nochmals herzlichen Dank an das ganze VSH-Team!! Es bleibt unvergesslich!!
Wir haben unsere Star Wars Motto Hochzeit hier gefeiert und es war einfach perfekt: Der Event-Verantwortliche hatte sichtlich Freude an der Idee und unterstützte uns von A bis Z mit tollen Einfällen und kritischem Feedback. Wir haben uns willkommen und abgeholt gefühlt. Die Infrastruktur bzw. die Möglichkeiten vor Ort sind riesig und für wirklich jeden Anlass anpassbar. Das Essen hat die Erwartungen bei Weitem übertroffen! Auch die Gäste waren begeistert: Die besten Schinkengipfeli und die beste Pfeffersauce, die wir je hatten. Auch das Service-Personal hat für viel Lob gesorgt: Freundlich und sehr aufmerksam. Zu guter Letzt war auch das Administrative, das mit einem solchen Anlass einhergeht, mustergültig simpel aufgesetzt, sodass wir uns wirklich auf die eigentliche Hochzeit konzentrieren konnten. Nochmals ganz, ganz herzlichen Dank an das super Team. Dank euch wurde unsere Hochzeit zu einem unvergesslichen und einmaligen Spektakel!
