From the Krimmler Tauernhaus you hike to the end of the Krimmler Achental. On this way you pass some very nice pastures. Shortly after the Innerkees Alm at the end of the valley, the trail to the Warnsdorfer mountain hut is located on the left side. After approx. 1,5 hours you will reach the hut. From here hikers have the opportunity to climb the Gamsspitzl, which provides a wonderful view to the sourrounding peaks on the Hohe Tauern. If you want something a little more comfortable you can reach about 15 minutes above the hut the fascinating ice lake - an impressive glacier lake.
