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.

You should take off your rucksack before crawling through, otherwise you will rub against the very low tunnel ceiling with it.

The Peterslahr region primarily features man-made tunnels and rock passages, rather than extensive natural cave systems. You can explore historical mine tunnels, former railway tunnels, and unique rock formations. These include sites like the Lammerichskaule Mine Tunnel and the Alvenslebenstollen.
Many of the underground structures in the Peterslahr area are historical mine tunnels, offering insights into past mining activities.

For challenging sections, such as the Cave tunnel in Naturpark Rhein-Westerwald, you might need to remove your backpack to crawl through, indicating a need for appropriate clothing and footwear.
