All paths lead to the impressive mountain panorama in the Tyrolean Oberland. But only one of two very special hiking routes leads into the beautiful Radurschltal, where a mudflow has formed an emerald-coloured lake. It is therefore impossible to estimate how long this natural jewel at an altitude of 2,200 metres will remain with us in its existing size of two football fields. The emerald lake is part of the beautiful hike to the Hohenzollernhaus with start and end point at the Wildmoos car park in the Radurschl Valley. The hike to Hohenzollernhaus with the mountain lake behind it is suitable for families and runs along the rushing Radurschlbach stream and past the Swiss stone pine sculpture park. A petting zoo with dwarf goats, chickens, hares and guinea pigs awaits the youngest mountain fans directly at the Hohenzollernhaus.
