FATMAP difficulty grade
Leave the car at the 1640 m bend above Tatz. Go up the road to the end of the road "Mattachra" and take the bisse on the right.
Follow him to the water intake at Jolibach. Go down by a right bank path along the stream for Jolialp. Exit on the Tatz-Giesch-Sue bisse which passes just over the Jolialp mountain pasture. Easy at the beginning and then across the Seebach...quite acrobatic! Change of level then we reach the recently enlarged road by a water catchment...
and we arrive at point 1640 m. Possibility to exit simply by the main road. Or reverse: enter from below (Unesco Heritage sign) 1640 m., shortly afterwards, on the rock written in red""13"" climb the small slope and take the bottom bisse with 1 passage equipped with chain to climb a rock! The leap then comes back easier, follow it until after Jolialp and the path goes up for the superior. Attention: not recommended for unsafe "tourists"!
