Your ticket to nature conservation

With the voluntary nature conservation franc of your day ticket, you make a valuable contribution to the preservation of endangered animals and their habitats. It is only thanks to your support and numerous donations that we invest over 2.5 million francs in nature conservation projects worldwide every year.

Thank you very much that we can count on your help!

The nature conservation franc is optional. If you do not wish to contribute it today, you can opt out of it at the checkout.
