Hochosterwitz is to the north of Klagenfurt. Parking is free in front of the castle. We can get to the top on foot and by lift.

Far on an opposite hill we could see Taggenbrunn which could unfortunately not be visited; so it's not worth linking the two trips.
The castle can be visited without a guide as well. In the court there are restaurants again.
We expected more (and we think the Hochosterwitz could offer more), so it only received one star from VÁRmánia.
