In 1997, the cantonal government decided to undertake the necessary restoration and preservation measures at the castle complex to preserve its historic features. After two years of renovation work, the Dorneck ruins are once again open to visitors. The view from the tower over Basel and Dornach is breathtaking.

The path is now heavily overgrown and the railings are loose in many places. So be careful when walking along it!

The Ermitage is a large and lovingly designed green area from 1785, with three idyllic ponds, several romantic grottos, historical buildings, pretty walking paths between the shore and the edge of the forest and, on top of it all, the castle ruins of Bierseck Castle, as the crowning glory of the whole. It is a wonderful place for physical and mental relaxation, but those seeking peace and quiet should visit outside of the holidays or weekends. It is a real visitor magnet. Warning! The grottos can only be reached on foot and via steep stairs. The rest of the garden is mostly wheelchair accessible and suitable for pushchairs. There are no parking spaces directly at the Ermitage! Free entry!
