From the car park at the reservoir, follow the road downhill for approx. 400 m. There is the entrance (yellow sign) to the Almrosen-Panorama Hike. After a slight climb through the forest in the direction of Kirstallexpress, from there it goes over a mountain pasture in the direction of Söggenaste. From here you need about 50 minutes to the Kristallhütte.
A very beautiful hike with well-maintained paths and wonderful views of the rear Zillertal and all 3000m mountains.
