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." (Heimat- und Verschönerungsverein von 1866 e. V. Ründeroth in cooperation with the Biological Station Oberberg, 2015. Created as part of the project “Hecke, Hohlweg, Heimat – Kulturlandschaftsvermittlung analogue und digital”.

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.

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.

You can't get in here. This is only intended for cavers and is tightly closed. The cave system is the largest in the Rhineland
