Thematic excursions
A series of free guided geological tours during the summer months are offered to a wide audience interested in discovering the country’s landscape from a new angle. Why not join us?

For already 10 editions (2013-2023), we are on the road with you to learn about the history of the rocks and landscapes of Switzerland. Thank you for your loyalty.
This year, five free guided geological tours are proposed and surprises await the participants. The number of participants is limited to min. 10 and max. 20 per excursion. You can always add your name to a waiting list, which we consult in case of any cancellations.
See you soon!
