Touring car park in the Jamtal.
It is not advisable to continue driving even when the barrier is open, as the police can check and the barrier can be closed quickly.
Follow the Jamtal to the Jamtalhütte (2-2:30h). The hut route runs uphill on a prepared path to the left of the river. If you don't want to head for the hut, you can stay in the valley bed and follow it.
From the lodge now a little further on (shorter! descent into the valley floor) and climb up to a ridge at an altitude of about 2.200m to reach the wide glacier plateau of the Totenfeld. Directly below the top of the Haagspitze it now goes up a steep slope. On top ski depot and in short climb to the summit.
From the depot it goes now quite steeply down to the Bieltalferner to 2700m. Unfortunately, there now follows a slightly hilly terrain with short, flat counter-rise.
If necessary, you can also traverse further up on the left, but the terrain becomes very steep there.
I recommend to use skins and ride the short descents with skins. That should be the quickest overall.
Cross above the Wiesbadener Hütte to the Tyrolean glacier and ascend it to the Tiroler Scharte. There again ski depot and by foot to the top of the Ochsenkopf. The climb is considerably more demanding than the first and can require crampons in icy conditions. I would have liked to have them.
From the Tiroler Scharte down the Jamtal valley over wide glacier areas. Shortly before the Jamtalhütte the area unfortunately becomes quite flat. Fortunately, thanks to the prepared path, you can make good progress from the hut. The snow on the east side of the creek is even more persistent further down in the valley. With a bit of luck you can get back to the car without walking.
