Ascent
Start at the valley station of the Drei Seen cable car and follow the piste past the Plenderleseen lakes, which are rich in fish but snow-covered in winter, to just before the mountain station of the Drei Seen cable car. The summit structure and cross are right in front of you right from the start. You now follow the flat cirque floor until the slope in front of the Gaiskogelscharte, 2660m, splits and narrows. In the current snow conditions, you can only climb up to about 60 meters below the saddle - otherwise you can usually ski up to the saddle. The twenty centimetres of fresh snow at the beginning of January may tempt you to climb up to the ridge on skins, but this is not advisable due to the lack of a base. Continue on foot over the initially wide hump and later somewhat narrower south ridge to the summit. The cross offers views of the Kühtai ski area, with the Lechtal Alps and the Wetterstein with the Zugspitze behind it. To the north-east, Karwendel and Inntal, Sellrain lies at your feet and the crowded pistes of the Hintertux Glacier greet you in the distance. Descent like ascent.
Alternatively, there is the north variant:
You carry your skis with you to the summit. A short, narrow gully runs directly to the north before very steep slopes open up in the Vordere Hirscheben. Only in absolutely safe conditions! Not possible in the current snow conditions. After a sparse larch forest, you reach the Sellraintal road above Haggen again. It is best to leave one car at the Weiderost to Haggen and take the second to Kühtai or the bus from Haggen back to Kühtai.
