Parking lot at Innerst (fee if attended).
From the parking up the open slope to the Northeast to the edge of the wood, then a bit on the forest road and soon to the left up a small road (quasi in opposite direction) to the next open area. Up this meadow and through a small strip of wood to the next clearing. After reaching the upper edge we see a small private hut (Eggerraste) at the forest road. Quite behind the hut the track heads up into the wood (shortening the forest road), crosses the forest road again and then turns, flatter now, to the pastures of Nonsalm.
We leave the alp far to the right and hike up the mountain pasture, first a bit through light wood, to the Northeast till we reach nice broken terrain. Here we meet the ascent track from Hausstatt (a boring forest road ascent). Now on through the heavily broken terrain, in changing but mostly moderate incline, to the Northeast towards the already viewable summit. Attention: The summit cross is very tall, so it will still take a while to reach it.
We climb the summit, now a bit steeper, on its southwestern slope.
If you are lucky to lay the first ascent track and if you are not familar with the shortcuts, then just follow the forest road from Eggerraste to Nonsalp and head, when the summit is viewable, up the meadowas to Northeast. The steep meadow parts can be avoided easily (Avalanche situation, wet snow).
Within the area of ascent or to the left (seen in downhill direction) down the wide sunny slopes to Nonsalp and then traversing back to the ascent route on the forest road.
Besides there is a more demanding and more avalanche endangered descent option from the summit down to the Northwest to Lafasteralp. From there on to Hausstatt (place a car there to get back to Innerst) or you walk for about 1 hour on a forest road from Lafasteralp around the mountain ridge back to the West.
