Königsforst Forest Trail

The Königsforst is directly connected to the Wahner Heide. For Cologne a quickly accessible jewel for relaxation. Whether on foot or by bike, many small and large paths and lots of forest. Always beautiful, no matter what time of year.

It's a lovely place to go for a walk. However, the main path is a combined cycle and footpath, so you can't really walk side by side as there are always cyclists on the road. That's a real shame.

On the way through the Königsforst, a forest area in the south of the city, which is particularly suitable as a shady hiking area in summer, depending on the route you take, you will also come to the highest point within the city of Cologne, the so-called Monte after its "discoverers". Troodelöh (Troost, Dedden & Löhmer). The fact that the forestry administration has removed the summit cross placed here can be classed as sacrilegious... a stone boulder now marks the - in itself unspectacular - measuring point.

The Königsforst offers a lot of well-marked hiking trails that are easy to walk from young to old. In addition to information boards, Wikipedia also has a lot of information about life in and with the forest on the subject of the royal forest. But the use of the forest from a military point of view is also very well described here and by historical societies. Naturally, there are also educational forest trails, etc. There is plenty of material for themed hikes.

Especially at the time of flowering a dreamlike colorful landscape, but also otherwise a great hiking area.

The survey with the idiosyncratic name is actually the highest point in Cologne's urban area. Everyone in Cologne should have climbed it once in their life. This is even possible without an oxygen device. The 118 meter high "mountain" is located in the Königsforst. The Cologne Alpine Club has erected an impressive summit stone up here. There is even a summit book. The name is made up of the surnames of the three “discoverers”.

Great protected landscape area with a lot of hiking trails and small highlights. Rich in water. There are many tours that open up the individual landscape areas of the Königsforst.

The boundary of Cologne's urban area runs through the Königsforst. Cologne's highest point is on it, Monte Troodelöh with a Height of 118.04 m above sea level. ..." https://de.wikipedia.org/wiki/K%C3%B6nigsforst
