The caves in Valkenburg a specially nice to visit in december at christmas time. Though a little commercial ( nog much santa items lots of normal stuff + food items) its cosy and attractive.
Just worth a visit. Whole of Valkeburg is made attractive arround christmas. Lots of bars, hotels and restaurant choice.
In the summer Valkenburg has lots of tourists there is lots to do in the surroundings.
Visiting the coalminers cave is worth while too. Old coalminers give guided tours and tell about the life the had under the ground. Interesting.
