Quelltuff der Lucius- und Emerita-Quelle
With a total of dissolved substances of 15,100 milligrams per litre, the Lucius spring is considered one of the most mineralised springs in Europe.


The highly mineralised Lucius spring is tapped together with the Emerita spring in the Büvetta Tarasp drinking hall, an impressive 19th century building. The drinking hall and the hiking trail have been closed since spring 2007 due to the danger of rock falls.
