The sulphur springs are located at the Tirler on the Seiser Alm. They are a geological natural monument. There are two springs that emerge at the upper edge of a marshy forest seal. At the larger spring there is a wooden fountain from which you can drink. The water is not poisonous, on the contrary, it has a purifying effect. The water is not tasty, because it smells like rotten eggs. The water has whitened those objects that are in the springs.
