The Valais is home to some of the most impressive gorges, caves and grottos in the Alps. Whether by suspended bridge, gallery or boat, exploring the dark grottos and deep gorges of the Valais is an absolutely thrilling experience. This unique and magical world was shaped over millions of years by the immense forces of nature. And not only are the gorges and grottos spectacular in themselves – the story of their discovery has fascinated visitors for decades.
