Workshops
* 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 the time to tailor your workshop or guided tour entirely to your requirements. Our guides are booked in several weeks in advance. Please note that in the event of cancellation, we will have to charge at least part of the agreed fee, as we have already incurred costs:
- If a guided tour or workshop is cancelled by the 19th day of the preceding month
25% of the agreed fee will be charged. - For cancellations after the 19th day of the previous month
50% of the agreed costs will be charged. - For cancellations less than 3 days in advance
100% of the agreed costs will be charged. - For cancellations regarding the hire of premises
20% of the agreed hire costs, with a minimum of CHF 50.
We thank you for your understanding.
