The impressive Jaun waterfall gushes out from the rock and cascades into a basin 10 metres below. The location is considered to have a very special telluric energy.
When the winter snows melt, up to 6,000 litres of water have been measured per second. The water streams, stays for a moment in a small basin, and then joins the Jogne river. The area around the waterfall has been equipped for people to visit and rest: paths lead you practically inside the waterfall, where you can feel the suspended droplets. In the evening, the place becomes even more enchanting as the waterfall is illuminated. It is even more magical on a winter's night.
For many years, the origins of the waterfall were unknown. Research has established that it is a karstic resurgence: water penetrates into the valley of Les Morteys, around 15 kilometres away, only re-emerging in Jaun after circulating underground for over ten days.
