In the mid-19th century, flooding from the Göhl River posed a major threat to the mine in Bleyberg/Plombières: Water repeatedly penetrated the tunnels and claimed lives. To prevent this, a diversion of part of the river was requested and approved in 1861. By 1862, a tunnel several hundred meters long was built beneath the rock, keeping the Göhl away from the mine. The construction cost approximately 200,000 francs. The tunnel is a technical monument to mining engineering from an era when hazards were deliberately controlled while simultaneously harnessing hydropower. It demonstrates how work-related accidents were prevented while simultaneously harnessing resources.

The site of the former Plombières mine is home to species-rich calcareous grassland meadows, now protected as a nature reserve. The exceptional flora and fauna of this area are due to the heavy metal-rich soils, particularly the presence of zinc in the subsurface. Among the natural meadow relics, visible traces of the former metal industry can still be found: – Walls from former foundry floors – Remains of old smelting furnaces – Stones from former industrial buildings A small stream meandering through the area further enriches the ecological diversity of this special place. The "Gueule" viewpoint, which offers a glimpse into a cave opening, is particularly impressive and worth a visit.

The Plombières region is characterized by picturesque river valleys and natural reserves that offer a 'canyon-like' experience, rather than deep, traditional canyons. The geological history, shaped by rivers like the Gueule and Gulp, has carved out interesting, gorge-like environments. You'll find unique features such as calamine lawns, which support rare flora adapted to heavy metal-rich soils, and the Geul sinkhole where the Gueule river disappears into a cave.
You can explore diverse natural features shaped by water and geological processes. These include winding river valleys like those of the Gueule and Gulp, unique calamine lawns, and geological peculiarities such as the Geul sinkhole at the Plombières Mining Site. You'll also find dry valleys like Horstergrub Dry Valley, which is not permanently aquifer but offers a distinct landscape.
Yes, several areas offer family-friendly experiences. For instance, Hohnbach Valley is noted for its beautiful and versatile paths, suitable for families. While not a canyon, the Lourdes Grotto, Banholt is also listed as family-friendly and offers a unique historical and natural stop.
Hiking difficulties vary. Trails like the Unpaved trail through the Teuvenderberg forest reserve are rated as intermediate, featuring spectacular descents that become deeper as you go. Horstergrub Dry Valley also offers intermediate trails. Some paths can be overgrown in summer, presenting additional challenges.
Spring is particularly recommended, especially for areas like Hohnbach Valley, where daffodil meadows are an absolute must-see. The unique flora, such as the yellow calamine violet, is also best observed during specific seasons. Summer can make some paths overgrown, so checking local conditions is advisable.
The Plombières Mining Site is a significant historical and natural site, active in lead and zinc mining until 1922. It now hosts a nature reserve with unique flora and fauna, and features the Geul sinkhole. Additionally, the Lourdes Grotto, Banholt offers a historical and religious site built from flints from a local quarry.
While popular spots like Hohnbach Valley can get crowded on weekends, exploring the longer stretches of the Gueule and Gulp valleys, or lesser-known sections of dry valleys like Horstergrub Dry Valley, might offer a more tranquil experience. The Nutons' Cave, located along a hiking trail, also provides a unique, perhaps less frequented, natural and folklore-rich destination.
Beyond exploring the gorge-like areas, the region offers various outdoor activities. You can find numerous hiking trails, including easy routes like 'Geulbenden Nature Reserve – Along the Geul Near Plombières' or moderate ones like 'Site des Trois Frontières'. For cycling enthusiasts, there are routes such as 'Laschet Tunnel cutting – Val-Dieu Abbey loop'. Running trails, including challenging ones like 'Forest Trail in the Eifel', are also available. For more details, check the hiking, cycling, and running guides for Plombières.
Given the varied terrain, including potentially overgrown paths and natural waterways, it's advisable to wear sturdy hiking shoes. Depending on the season, be prepared for nettles and blackberry bushes, especially on trails like the Unpaved trail through the Teuvenderberg forest reserve. Water, snacks, and appropriate weather gear are always recommended.
Yes, the Nutons' Cave is steeped in local folklore. According to legend, nutons (or lûtons/goblins) are small, clever beings who perform minor repair work in exchange for offerings. They are said to inhabit caves and underground passages, much like the dwarves of Germanic tradition, adding a mystical element to your exploration.
Yes, the region offers various circular hiking routes that allow you to experience the diverse landscapes. For example, the 'Site des Trois Frontières' offers a moderate loop from Moresnet-Chapelle, providing views of the undulating terrain. Many trails along the Gueule and Gulp valleys are also designed as loops, allowing for comprehensive exploration of the area's natural beauty.
The Plombières geographical area is defined by its river valleys, particularly those of the Gueule and Gulp, which have carved out significant gorge-like environments. The presence of dry valleys, such as Horstergrub Dry Valley, and the undulating topography of the Three Borders Region, including the Vaalserberg, all contribute to the dramatic and varied scenery that gives the area its 'canyon-like' character.
