Guided tours for groups
Tours in the exhibitions and geological city tours
* Rates are per group (each with a maximum of 12 people) or per school class (with a maximum of 24 people). For school classes of 25 or more people, different rates apply. For geological city tours, rates are per group, each with a maximum of 20 people.
** If a guided tour begins during opening hours but ends outside of opening hours, the extra cost is calculated proportionally.
We take our time to prepare a workshop or guided tour to your satisfaction. Due to the numerous short-term cancellations in the last few months, we see ourselves obliged to invoice the costs incurred in case you cancel a workshop or guided tour on short notice. Therefore please note:
In the event of a cancellation 3 or more days in advance we will charge
- for School groups and groups up to 12 people 60 CHF;
- for groups with more then 12 people 110 CHF.
In the event of a cancellation less then 3 days in advance we will charge
- for School groups and groups up to 12 people 100 CHF;
- for groups with more then 12 people 150 CHF.
In the event of a cancellation less then 24 hours in advance we will charge
- for School groups and groups up to 12 people 160 CHF;
- for groups with more then 12 people 210 CHF.
Thank you for your cooperation!
