On display are themes related to historical and current navigational equipment and principles, marine life, and the geology of the Sletterhage area.
Until 1985 SOK, Søværnets Operative Kommando, the Danish Navy Command, had a monitoring station at the lighthouse, where passing ships were identified.
Close to the lighthouse is Tyskertårnet, the German Tower, a watchpoint built during WW2 for surveillance of the Kattegat in occupied Denmark.
From here one can see southern Djursland, the Mols Hills, and the eastern coast of Jutland, plus the islands, Tunø, Samsø and Hjelm, as well as the Ebeltoft-peninsula.
The south-facing hills surrounding the lighthouse have a dry microclimate giving living conditions for several not often seen insects, including some butterfly species.
