During the opening hours of the Cioss Prato restaurant, you can visit the underground mineral grotto and marvel at the huge crystals from the Gotthard region: rare smoky quartz, iron roses and typical radiant quartz from the Bedretto valley have been embedded in a magical world with great attention to detail.
