Behind Gelmerhütte follow the trail. On a bifurcation branch off left; you will find «Ofenh.» painted on a boulder. The faint trail leads you to the beautiful alluvial plain Obrist Diechter with its several creeks, sandbanks and cotton grass fields. The alluvial plain changes every year so consider the following description as a guideline: walk around the plain on the right-hand (eastern) side. On its northern end cross a creek and turn left (west) before the scree walls. Now on the western rim of the plain cross another series of small creeks and follow the left (western) creek to the scree slope below Üssri Garwiidilimi. Begin the ascent on this scree slope rather on the northern rim close to the rocks, where you find a faint trail and cairns. Now ascend on these scree slopes and block fields west- and northward up to Üssri Garwiidilimi (2684 m). Continue the ascent on the broad scree ridge towards Ofenhoren, then walk left (west) of the Ofenhoren south ridge on névés and scree to a depression. Hike increasingly steeply towards the southwestern ridge, then climb the last part keeping to the left-hand side before exiting on the ridge proper. There are some old, blue marks, which do not help much. Now it pays off to ascend along the ridge to the secondary summit (2933 m), which offers a splendid view into Haslital and Guttannen deep below. Now take a few steps down and then up again to the main summit; at the end easy climbing is required. Descend back to the cabin on the same itinerary, without the detour to the secondary summit, of course. In any case it is better to go back on the south-western ridge, before descending in the scree depression.

From Gelmerhütte hike back to Gelmersee on the marked mountain hiking trail.

On the descent walk around Gelmersee on its south shore. Very beautiful, add roughly 30 mins., T3–.

Ascent without using Gelmerbahn: from the bus station Kunzentännlein hike up to Gelmersee. Add another hour.
