Monte Troodelöh, Summit in Rath/Heumar district, Germany.

Monte Troodelöh is the highest point in Cologne's municipal area, at 118.04 m above sea level, on a rising slope in the Königsforst by the Wolfsweg, between the Pionier-Hütten-Weg junction and the Brück-Forsbacher Weg crossing. A boulder at the spot carries a bronze plaque with the height; the ground east of the Wolfsweg climbs to about 130 m at the Großer Steinberg, which already belongs to Bergisch Gladbach.

In November 1999 a group of Cologne city administration employees hiked to the then largely unknown high point, recorded at 116.7 m, and set up a temporary summit cross. After the city office for real estate and surveying re-measured the area in 2000, the height was corrected to 118.04 m above sea level. In 2001 the Rheinland-Köln section of the German Alpine Club installed a new cross with a bronze plaque, which the forestry administration soon replaced with a boulder bearing the plaque.

The summit's name comes from a 2001 competition in the city staff newspaper, combining the surnames Troost, Dedden and Löhmer of three employees who found the spot in 1999. A boulder now carries the bronze plaque that was first mounted on a summit cross by the Rheinland-Köln section of the German Alpine Club. Hikers sign a summit book kept in a compartment there; by April 2024 fourteen filled volumes were stored in Cologne's Historical Archive. The hill also appears in the Kasalla song "Mer sin Eins", in the same line as the Pletschbach stream.

The Wolfsweg trail provides direct access to the summit and connects with multiple hiking routes through the Königsforst. The climb is brief and straightforward, manageable for casual hikers.

The name combines the surnames of three city employees - Troost, Dedden, and Löhmer - who brought attention to the hill through an employee newspaper competition. This unusual naming shows how a local everyday project became a city-wide landmark.
