The container is a coffee glass.
It contains a log book, a pen, a batch of our scout clan, 11 Danish krona.
You can drive very close to it. It is placed just outside an old castle, which is used as a scout centre today.
Small note on cache maintenance: When I was in Poland, I visited the Polish scouts, which have agreed to look after it. I often email them, and if it some day is missing or need care, they have assured me that they will take care of it.
