Valkenburg aan de Geul

The only hilltop castle ruin in the Netherlands overlooks the small town, and inside the marl caves are a coal mine museum and the famous underground Christmas market.

Valkenburg aan de Geul lies in the Geul Valley of Limburg, the southernmost province of the Netherlands, about 12 km from Maastricht. It is one of the few hilly areas in the country. The town is built beneath marl hills. For centuries, stone quarrying has left behind tens of kilometres of underground tunnels, which are now used as caves, museums and a Christmas market venue. The castle ruin on the hilltop is the only hilltop castle in the Netherlands, and since the 19th century the town has been the Dutch people's favorite holiday destination.

Sights are concentrated within walking distance. At either end of the old Grotestraat are two medieval gates, the Grendel Gate and the Bekker Gate. The castle ruin is linked to secret underground passages. On the west side are the Gemeentegrot municipal caves, the Coal Mine Museum, a replica of Roman underground tombs, and the Tilmé 2000 thermal spa. On the south side, a cable car goes up to Wilhelmina Tower, next to a fairy-tale forest with slides. In the countryside, you can walk or cycle along the Geul River to the Geulhem cave houses and Schaloen Castle, as well as to the Netherlands American Cemetery about 6 km away.

The town can be enjoyed in every season. Spring and autumn are the most comfortable for walking and cycling, and summer is busy with tourists. The cave Christmas market, from mid-November to late December, is the most distinctive event. It is extremely crowded on weekends, so visit on a weekday and book tickets in advance.

Getting there: a train from Maastricht takes about 15 minutes, and from Amsterdam about 2.5 to 3 hours. The town itself is walkable.

Plan to spend 1 day, or stay overnight if you want to enjoy the spa or go hiking. Note: the caves stay at about 12°C all year round, so bring a jacket. There are many slopes and steps, so wear non-slip shoes.
