The name goes back to Li Trimbleu, a well-known tourist steam train that ran on these tracks between the coal mine in Blegny (Blegny-Mine) and Mortroux from the 1970s until 1991. Originally, the route (line 73) was an important connection for freight and passenger transport from 1904 onwards.

The Chemin du Trimbleu is today an idyllic, car-free cycle and walking path that runs along the route of a historic narrow-gauge railway line. It leads through the scenically attractive valley of the Berwinne river and connects Dalhem with the neighboring town of Mortroux. The absolute highlight of this path is the historic, 144-meter-long Dalhem tunnel, which was extensively renovated, asphalted, and reopened with full lighting in 2020.
