There is also a route over the Brandjochspitze when you start from Innsbruck.
From Innsbruck Hungerburg to Höttigner Alm -> Frau Hitt Sattel -> Brandjochspitze --> and then up to Solstein (Grade III)
Thanks for the information Peter! Have you done the climb or do you have any topos?? Sounds very interresting...
I' ll add this to the text of the main page.
Cheers Lukas
