The cave trail is one of the themed trails in the Bergisches Hiking Region. In 2019, after 20 years of searching, researchers found an entrance to a cave that they suspected was in Mühlenberg near Ründeroth. In this cave, called the "Windhole", they discovered a cave system of incredible dimensions, crystals, limestone formations and impressive cavities that no one had ever entered before. At more than 8,000 m, the "Windloch" is the largest cave in North Rhine-Westphalia and is therefore one of the top 10 in Germany. On this cave trail, foray no. 14, which opened in 2020, you can get to know the work of speleologists using the information boards and audio stations. The cave is not open to the public.

"A GUIDED TOUR THROUGH THE STAPLITE CAVE TO THE CRYSTAL GROTTE IS AN IMPRESSIVE EXPERIENCE. Just after entering the cave, you are 7 meters underground. The temperature here is only about 8 degrees Celsius all year round. You can admire the many slender stalactites hanging from the ceiling and the stalagmites that have grown thicker from the floor. The highlight of the tour is the crystal grotto, a former cave lake lined with calcite crystals. The cave also contains the deposits of a coral reef from the Devonian period. The Wiehl stalactite cave was discovered in 1860 by blasting in a limestone quarry. In 1927, it was opened to the public after extensive security measures. The Wiehl registry office offers a special highlight. You can get married in a grotto 30 meters underground let..." https://www.bergisches-wanderland.de/poi/tropfsteinhoehle-wiehl https://waldhotel-wiehl.de/tropfsteinhoehle/ https://www.wiehl.de/tourismus/sehenswuerdigkeiten/tropfsteinhoehle/

This mountain excursion No. 14, the cave trail, is an entertaining walk. Again and again there are beautiful views far into the country and into the Aggertal. The Haldyturm offers a great 360° view of the Bergisches Land. Informative display boards tell about the discovery of the wind hole.

The entrance to the Windloch cave system on Herderstrasse in Ründeroth is quite unspectacular. It's hard to believe that a gigantic cave system extends 15 meters below the blue metal cover. The well-made, very vividly designed page https://denkmal.arctron.de/windloch/ allows interested people to explore the spectacular cave at least virtually in 3D.
