Sint-Pietersberg offers a unique mosaic of open chalk grasslands and light-permeable forests, worth visiting for every nature lover. On the 'Sint-Pietersberg' you will feel like you are in a foreign country. Where else can you find such beautiful hills and such a special marl landscape?

The Neercanne castle is built on the original site of Roman fortifications whose caves still exist and are used as a wine cellar. In the hall, the original staircase with a railing on wide columns is still present. Weapon trophies are depicted in relief on the ceiling. Currently, the castle is used as a hotel and restaurant. The restaurant has been awarded one star by the Michelin Guide.

Very challenging and very steep. Be careful here. There is a rope, best to use it.

Along the rippling Geul River, an impressive marlstone wall rises, a silent witness to Limburg's underground landscape. These calcareous rocks were used for centuries for construction and crafts and now offer a fascinating sight for hikers and nature lovers. The wall forms a natural boundary along the water and, in some places, harbors small caves and niches where flora and fauna have found a home. The contrast of the white marl against the green foliage and the glistening water of the Geul makes this a particularly photogenic and tranquil spot during your walk.

Deep in the marl hills of Valkenburg lie the famous Neolithic flint mines, one of the oldest industrial sites in the Netherlands. People dug marl here as early as 2800 BC to extract flint, a hard rock used for tools such as arrowheads, knives, and axes. The tunnels extend dozens of meters beneath the hill and offer an impressive glimpse into how our distant ancestors shaped their habitat. The mines are unique and offer insights into the daily life and technological knowledge of the first farmers and hunters in South Limburg. Over the centuries, the tunnels have sometimes been flooded, subsided, or partially collapsed, but the traces of mining are still clearly visible. Today, parts of the flint mines can be visited via guided tours or special routes where you can literally follow in the footsteps of people from 5,000 years ago.
