The marble balls produced in the Kugelmühle open-air museum now serve as souvenirs and are available from the Gruber family in the Röhrmoosmühle and from the information office in Seeham.

The Kugelmühle is part of the Teufelsgraben eco-cultural project. It is located directly on the hiking trail, right next to the Wildkar waterfall and can be visited at any time. You can find all dates here
