Top 6 Caves 우르미츠 주변

A super short but challenging trail. Highly recommended. To have a good route to continue on, it's a good idea to turn right after the uphill section.

A fenced area where slate was formerly mined. Is privately owned

Walled-up cave entrance directly on the Aubach.

Very interesting, these caves.

nice secluded trail for hiking.

Between 1627 and 1858 the tuff in the Krufter Bachtal was mined by underground blasting, which is evidenced by boreholes in the walls. The definition of the period is based on the following facts: The use of blasting technology in European mining was first documented around 1627. Because of the dangers, underground tuff extraction was banned in 1858. For mining, a good 3 meter wide corridors were driven into the stone at a depth of about 15 meters. The distance between the aisles was about 20 to 40 meters. A rectangular underground tunnel system of approx. 250 m × 150 m was created. The blasting had already broken the tuff into smaller pieces. Crushed again by hand, the stones were stacked on arks for days. After a drying time of about 2 weeks, the stones were ground into fine rock powder, into trass. Trass has hydraulic properties and was used in conjunction with lime to create a waterproof mortar.

This trail is located in the Mallendarer Bachtal, but at best you can see the exit if you look carefully. So drive up a partly quite steep loop and off you go. Very loose rock in dry conditions, but very easy to drive on. All switchbacks are easy to drive because they have a comfortable radius 👍 I would call the trail S 0.5 😜
