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

It's a shame that the Sandkaul Caves are used by some people as a dumping ground for their garbage.

The Sandkaul near Ettringen in the Volcanic Eifel.🖤 This former volcanic rock mining area is located on the edge of the Hochstein volcano, north of Ettringen on the L 82 highway, about 500 meters past the end of the village.🖤 Sad background: 🪖During World War II, the Ettringen caves were drilled into the rock...to protect against attacks🧨... 😑🙏🏼

The caves around Nickenich are rich in history. The Mendig Lava Cellars, for instance, are an extensive network of man-made tunnels created by basalt mining dating back to the late Middle Ages.
