Visitors can explore a rich geological diversity in the Binntal valley thanks to its exceptionally varied flora. The treasure of this valley is concealed within the mountain – nature has made the Binntal valley one of the regions of the Alps which is richest in mineral deposits.

The Binn Valley is one of the world's ten largest mineral deposits, known since the 18th century. Located next to the deposit Lengenbach, Switzerland's only rock crystal mine is worth a visit. A didcatic trail focusing on the region's geology (Gesteinserlebnisweg) is a good introduction. The area's tourist board is preparing a public rock collection spot but even visitors today should not forget to bring a hammer, a chisel and a box to carry home one's finds. Do not expect to get rich – it is nonetheless an enriching experience.

How to get there: Drive or take public transportation from Brig to to Binn via Fiesch.
