Club, with us you will find an exciting offer for all groups.

Throughout the year, from Monday to Saturday, the Hagerbach Test Gallery offers various attractions.

We are particularly pleased that, together with our professional partners, we can offer exciting activities in the beautiful Heidiland and the incomparable UNESCO World Heritage Tectonic Arena Sardona, both in summer and winter.
