    The Nazis built aircraft engines in these old trachyte tunnels, later serving as air raid bunkers. Today only bats live here. The Ofenkaulen belong to the most important bat winter quarters in southern North Rhine-Westphalia and northern Rhineland-Palatinate. Out of respect for the animals, which can be wakened from their hibernation, especially in winter, and then starve miserably, they should not be bothered.General hint to the old tunnels of the Ofencaulen: the Ofenkaulen lie not only in the nature reserve, but are also an archaeological Bodendenkmal! After several accidents (including fatal ones), the entrances were largely closed off with concrete and steel several years ago. Behind it lies a dark, cold and unsecured labyrinth that stretches over several floors and countless galleries and shafts. Parts of it are at risk of collapse or have already collapsed, as numerous surges on the surface show. Many good and educational information can be found today but on the Internet, including pictures and videos.

    In addition to the described bunker facilities, there is also a MTB trail worth driving.
