Top 20 Caves 마옌-코블렌츠

Impressive colors, especially now in autumn.

The Trass Caves in the Brohl Valley are deep, branching cave passages made of volcanic trass rock – formed around 13,000 years ago by the eruption of the Laacher See volcano.

The small cave was once part of a mine, used during the First World War due to a shortage of raw materials. Today, the entrance is a mysterious spot at the edge of the hiking trail, surrounded by trass rocks and jungle-like vegetation. ⚠️ Caution: The cave is not accessible – there is a risk of collapse.

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
