The MN18 Observation Bunker is part of the first line of defense of the Position Fortifiée de Liège (PFL), a network of bunkers built in the 1930s to defend Belgium against a German invasion. MN18 was the 18th bunker in the Margarins-Neufchâteau sector and equipped with an FM turret, recognizable by its tapered shape. During the German attack in May 1940, the bunker was destroyed by a 50 kg shaped charge placed on top of the turret, just where the periscope was located. The damage is still visible, making MN18 a tangible reminder of World War II. Right next to the bunker is the Knuppelstock orientation table, an impressive work of blue limestone with a diameter of 1.5 meters and weighing approximately one ton. The relief of the surrounding landscape is engraved on it based on data from the National Geographic Institute, with bronze details indicating the visible points. The table is also accessible for the visually impaired thanks to its tactile elements. The project, carried out by local organizations such as Qualité-Village-Wallonie and the municipality of Aubel, is unique in Belgium.

At this point, history and landscape converge. The MN18 observation bunker, a silent witness to the Second World War, still stands as a reminder of a turbulent period. From the bunker, you also have a unique view of the surrounding hilly landscape. Next to the bunker is the Knuppelstock orientation table, a platform that indicates the names and directions of villages, hills, and landmarks in the area. It's an ideal spot to get to know the region better and to enjoy a panoramic view of the border area between the Netherlands and Belgium.

INFO board [nl]: Mill Nekum to Prins Bisschopssingel The Roer en Overmaas water board has widened the Jeker from the Nekum mill to the Prins Bisschopssingel in Maastricht to prevent flooding. The construction of a fish ladder removed the fish migration bottleneck at the mill (until 1930, glaze was ground here to make pottery waterproof). Fish can now easily pass the mill to lay their eggs upstream, among other things. In the Aquadra project, the water board is working across borders with ten water managers in South Limburg and Belgium to further improve water quality and prevent flooding in the catchment areas of the Jeker, Voer, Berwijn and Geul.

The vast site, once used for limestone quarrying, is now a beautiful nature reserve. You can explore the steep walls of the quarry, which create a dramatic landscape of rocks, grasslands and forests. The route winds along the edge of the deep quarry, with panoramic views of the surrounding nature.

There is a winery behind the bridge. Note that it is not open on Sundays. It is best to research the opening times before the hike.

Can be reached in different ways, but the stairs with its 215 steps, the viewing platforms and the small part of the corridor system at the bottom are special. In the excavation, look not only at the beautiful pieces of limestone and the many water features, but also at the flora and the more hidden pools with reeds and water birds.

In 2017, a temporary swimming area was opened in the ENCI quarry. The lake was intended for recreational use, but it soon became a swimming pool and this had many negative consequences (nuisance, litter, parking nuisance). For these reasons, swimming in the ENCI quarry is now prohibited. The ENCI quarry is the ideal place to take a nice walk. A brand new hiking trail was put into use in 2017. It is possible to descend the quarry via the viewing platform on the Luikerweg. The walking path then runs through an old piece of tunnel system and continues its way via the lime grasslands and the pond to the other side of the quarry.
