Welcome to Pro Natura Center Aletsch

The Pro Natura Center is located in Villa Cassel in the canton of Valais amid the magnificent mountain landscape surrounding the protected areas of the Aletsch Forest and the Great Aletsch Glacier. It is also your gateway to the UNESCO World Heritage Site Swiss Alps Jungfrau-Aletsch.



The center is closed from October 16th, 2017 until June 15th, 2018.


After a successful summer in 2017 we closed the center and made the house safe for the wintertime. While we are all busy preparing for the next season down in the valley, the Villa Cassel is in hibernation.


Reopening in summer 2018
The Pro Natura Center will reopen on June 16th, 2018 with a comprehensive new program of excursions, courses, exhibitions, etc. and will be open until October 21st, 2018.

Come and visit us. We will be delighted to have you as our guest!
