Landmark
Valkenburg aan de Geul is a unique tourist destination tucked away in the hilly landscape of southern Limburg. It is renowned for its extensive marlstone caves, such as the Velvet Cave and the Municipal Cave, where visitors can explore miles of underground passages filled with historic charcoal drawings and sculptures. Perched above the town is the dramatic ruin of Valkenburg Castle, the only hilltop castle in the Netherlands, offering panoramic views of the Geul Valley. In the winter months, Valkenburg transforms into a 'Christmas Town,' hosting one of Europe's most unique underground Christmas markets inside the caves. For cycling fans, the Cauberg hill is a legendary climb, frequently featured in world-class races like the Amstel Gold Race. After exploring, visitors often unwind at the Thermae 2000 spa resort. With its yellow marlstone architecture and rolling hills, Valkenburg provides a completely different vibe from the flat polders of the north, making it a favorite for outdoor enthusiasts and spa-goers alike.
