Caution: please note that the road is in bad shape!
Drive to Irschen (Austria). Once in Irschen follow the signs for Weneberger and than for Weneberger Alm. The last 6 kilometers of the dusty road are in really bad shape! There is a parking at the destination and the hut Unteralmhütte in the vicinity.
Head to the Unteralmhütte, where the trail to Scharnik begins. The trail first crosses a mountain spring before it ascends to the signs that direct you to the ascending trail for Scharnik.
In the continuation, enjoy the trail which opens up while it slowly ascends. The trail crosses a mountain spring and then it reaches a spot with cosy recliners. After 45 minutes of walk (from last signs by the Unteralmhütte) the trail joins with the one from Ochsnerhütte. Continue left and after 30 minutes of a slightly steeper trail turn right (left is Lamnitzsee). Walk up the trail for another 20 minutes and you will reach the Gursgen Törl at 2445 m, where you should turn right. From here the trail follows the ridge all the way to the top. The terrain is not difficult (no scrambling is neccessary) but still you may find this part to be the most difficult of all the trail.
