blasting demonstrations

A successful event highlight!

 

For smaller groups of up to 60 people, we recommend the live blasting demonstration "Regular". This has the advantage that it can be carried out close to the restaurant/exit of the tunnel and can therefore be used as a good conclusion to a guided tour or briefly during a meal break.

 

For the complete experience for all senses and twice as many detonations, choose the live blasting demo "Big Bang 4d". A little deeper in the tunnel and more spacious. This blasting can be demonstrated in front of up to 200 people and is especially well suited for larger company events looking for a special supporting activities. The location can also be set up very well for a rustic aperitif, which is then concluded with the blasting before continuing to the event cavern for dinner.

Guided Tours

Experience tunnel construction and research

 

On the tours through our dynamic tunnel system you will learn many interesting and worthwhile facts about tunnel construction and tunnel safety.

 

Our dedicated and friendly bear guides will not only tell you the stories written in our tunnel, they will also show you current and future-oriented projects.

 

The tours can be adapted to your needs.

Teamevents and teambuilding

An ideal "playground" - let's do it together!

 

Fun and games are the order of the day with activities such as the Hagerbach Challenge, marble run construction or the Domino Record attempt.

 

At Next Level Team Building we can also put together a completely personalised programme for you to convey your company values in a playful and practical way.

Summer activities

The combination of opposites makes it outstanding! Let the summer come!

 

Did you know that together with our partners from OUTIVITY Outdoors and Schiffsbetrieb Walensee AG we offer exceptionally contrasting group offers in beautiful Heidiland?

 

The constant component in these "summer offers" is the mountain. After a leisurely cup of coffee, we go on a tour of the company, which ends with an impressive blasting demo. After a delicious lunch inside the mountain, we head out into nature. A leisurely boat trip on Lake Walen, a tour on the comfortable e-country bikes through beautiful Heidiland, or hiking and tobogganing on the beautiful Flumserberg.

Winter activities

Our winter offers for groups have one constant feature: experience the Hagerbach Test Gallery in combination with superb activities in the region.

On the move with snowshoes or huskies in the Heidiland region, or right here above the Gallery with the great goat trekking and a visit to one of the most beautiful stables in Switzerland as the starting point for a very special evening.

Our Guides

What the heck is a bear guide?

50 years of tunnelling have already brought forth some unusual stories. Nobody knows exactly how long the term "bear guide" has been around in the tunnel.

According to the legend, the term comes from: A tunnel leads into the mountain like a cave for the bear, who then safely protects his "pack" there and also leads it out again.

The catch? In the animal kingdom, bears are usually solitary animals and when in a group they are officially called detectives or sloths. But our Stollen Guides or "bear guides" are anything but lazy.
