We have been climbing for more than 1 hour now, and we can see our goal: Watchtower 14.
That's where the CITS guides stop: they don't risk sending their group on the "most dangerous part of the Great Wall" .
And dangerous it is: the peak you see behind the tower is the highest part of Simatai, and there the Wall is only 1 brick thick. It is possible to climb it, though, but you can fall pretty deep ;o)
