The hike starts from Mittenwald (Scharnitz would have been better but alas, the border is closed now) and we climb to Brunnsteinspitze from the west side of the mountain via Brunnsteinhutte. We try the Klettersteig (B) (Mittenwelder Klettersteig) to Kirchlspitz and then Karwendelspitze or we can avoid the Klettersteig in the extreme case.
Both the ways there is a considerable amount of scrambling. So, it’s definitely not for inexperienced hikers but only recommended for highly experienced regular hikers.
