The circular hiking trail, approximately 24 kilometers long, leads through former mining towns, relics of the steel industry, and tranquil nature reserves of the Minett region. Along the route, disused mines, former railway lines, and authentic villages tell stories of work and daily life, of change, resistance, and new beginnings. It's a trail for everyone who wants to explore history, enjoy the scenery, and experience what has shaped this region—and what defines it today. More information about the industrial past can be found at the "Minett Park Fond-de-Gras" close-by. The Sentier des Mineurs is designed as a circular route. However, since the 24 km distance can be challenging, it's possible to split the trail into two shorter loops using a shortcut. This allows you to explore the Sentier des Mineurs at a more relaxed pace over two days. Suggested itinerary: Day 1 (18.5 km) Fond-de-Gras – Lasauvage – Differdange – Baggerweier (Niederkorn) – Fond-de-Gras Day 2 (9.8 km) Fond-de-Gras – Baggerweier (Niederkorn) – Pétange – Lamadelaine – Fond-de-Gras The connection between the two loops is via a section of the Minett Trail, which provides a direct route back to the starting point. This shortcut is signposted at the relevant junctions between the Sentier des Mineurs and the Minett Trail. Information panels at the trail markers also indicate the alternative route. This division makes it possible to perceive the scenic and cultural-historical features along the route more intensively, without having to cover the entire distance in one day.

Nowadays, it’s hard to imagine that the peaceful little valley of Fond-de-Gras was, until the 1960s, one of the country’s leading mining centres. At the Minett Park Fond-de-Gras, over 100 years of industrial history in the south of Luxembourg are brought vividly to life. The Train 1900 steam train links Pétange with Fond-de-Gras just as it used to around the turn of the last century. The “Minièresbunn” miners’ train takes visitors through a tunnel where iron ore used to be extracted, from Fond-de-Gras to the mining village of Lasauvage and as far as Saulnes (in France). In summer, the Blues Express music festival and the Steampunk Convention make this open-air museum rock! Fond-de-Gras was one of the most important mining centres in Luxembourg. However the extraction of iron ore ended in 1955. In 1964, a landslide on the Fond-de-Gras – Pétange railway line put an end to all railway activities. A few years later, volunteers commit to run a tourist train with historic steam locomotives. The first "Train 1900" circulated in 1973. A few years later, an old mine is opened again and can be visited thanks to the mining train "Minièresbunn". Today, at the Fond-de-Gras, several historic buildings have been preserved: an electric power station, old grocery store, rolling mill train, railway station and railway sheds, testifying to the mining activity that took place there for nearly a century. The Minett Park Fond-de-Gras can be visited free of charge all year round; the activities are linked to specific days of the week and times. The Minett Park website provides information about the opening times.
