An old quarry that is now a nature reserve.

This information board for the cave path is right next to the Walbach, which you follow for a short stretch here. Interesting facts about the "stream sinkhole" of the WALBACH: "The "Walbach", a small stream, flows 50 meters above the Aggertal floor. However, the stream does not usually find the usual route into the Agger. Shortly before the Aggertal cave, it "disappears" underground. Color samples showed that the Walbach continues to flow underground and flows into the Agger in the middle of the cottage gardens in Ründeroth. This stream sinkhole is a geological and hydrological peculiarity. Before the Second World War, there were plans to divert the Walbach at today's Haus Hohenfels residential and nursing home and to lead it down into the Agger as a waterfall from the Weinberg hill. However, the plan was rejected due to water law obstacles. The area around the stream sinkhole and the Aggertal cave are part of the "Altenberg and Aggertalhöhlen" nature reserve, which also includes the two wooded hilltops above it."

A former mining tunnel of the Bochumer Bruch limestone quarry offers a museum in an extraordinary atmosphere: the Wülfrath Time Tunnel. The 160 meter long tunnel tells 400 million years of earth's history with multifaceted objects and fossils on a natural history trail.

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/

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.
