The freely accessible trass caves in the Brohltal are located below Bad Tönisstein on the Brohltalstraße (Federal Highway 412) at the height of the "Jägerheim" inn. The caves were formerly used by the trass millers: they had the raw material, the freshly cut trass "arks", dried there.[1] There are parking spaces for cars near the caves. The Kell Cave and Gorge Trail, a circular hiking trail, leads past the trass caves. Source: https://www.aw-wiki.de/index.php/Trassh%C3%B6hlen_im_Brohltal

The tunnel addresses the history of mining. The last time I visited the tunnel, there were lots of small bats living there. The history is also explained in detail on site.
