This location is recommended for courageous buses due to its narrow entrance. However, the spot offers a beautiful view of the fortress as a reward. The only downside is the train service, but it did not cause any issues for us.
The view is almost unbeatable, but that's the only positive aspect. The parking space can only be accessed through a bicycle path, which is very bumpy and slanted. It gets very muddy when it rains. The train traffic kept us awake at night, with many loud freight trains passing through.
This is a beautiful parking spot surrounded by beech trees, but the road leading to it (from the direction of the fortress, at least) has a no-entry sign from May 1st to October 31st. We decided to turn back and find an alternative.
