Roger Houghton has organised the Herzogstand walk for many years (25+)
It is a little early this year due to Easter being early. He always holds it on Ascension Day... his little pun.
I've been on it many times. It's a good walk, since it is one of the first mountains the views from the top are of the Alps on one side and the planes stretching to Munich in the distance on the other.
The food almost at the top is good and there is a cable car for the lazy ones.
