Beautiful hike but dog owners beware: after the waterfall there is a very steep metal staircase. I had to carry my 20 kg dog up there, which was very dangerous. The path next to it is crooked, has slipped, is unsecured and the slope goes steeply down to the waterfall, so it's not an option.

This boulder is called Grossi Flue. It weighs a whopping 3,500 tons and has a volume of 1,200 cubic meters. The boulder was brought here by the Rhone Glacier – this is evident from the hornblende gneiss. The enormous boulder was purchased by the Swiss Society of Natural Sciences in 1869 and placed under protection. Otherwise, it would likely have fallen victim to railway construction.
