Tips from the Community
In the middle of Hesselholt Skov, part of Rold Skov, the ground opens up to one of the region's most fascinating geological phenomena. The sinkhole Røverstuen is about twelve meters deep and measures approximately 35 meters in diameter. Sinkholes form when percolating rainwater dissolves chalk, creating a cavity that eventually collapses. However, the exact cause of Røverstuen has not been fully clarified to this day, as the chalk lies unusually deep here. What geology leaves open, legend fills. A band of robbers is said to have once lived at the bottom of the hole, well hidden next to the old forest path Roldvej, and listened to passing travelers with ropes and bells.

A walkway and ladder lead to the grotto. In rough seas, you might get your feet wet when entering.

This passage grave from around 3300 BC is in good condition. A short visit on your tour is definitely worth it… although you can only go in on your knees
