One of the routes were rated D like the one we had done a few days before near Kossen. However this one seemed a tiny bit harder. Perhaps it's just the different rock and the way the cables had us off balance.
It had a very nice descent route as well but by the end we concluded that it was fairly strenuous the whole way round!
The second route was fairly easy, if a bit slick on the rocks, right above the waterfalls so it was very loud, and a really cool location!
The via ferrata continued much, much higher above us, but we decided to leave that very hard E/F route for another day....
