For a whopping month and a half Valkenburg, a small city in the hilly south, hosts multiple grand Christmas activities.
The multiple underground Christmas markets in the gorgeous caves of the Cauberg are without a doubt the main attraction of the Christmas City. The merchandise is not the most diverse, but their setting is unique in the Netherlands.
The most popular ones are the the Municipal and Velvet Cave. The newest addition to the Christmas market caves is Mergelrijk, where you can find brittle marlstone all around you.

Other activities include Santa’s Village, which is the main market above ground, the Christmas Parade, the delicious Route d’Amuse and Magic Sand, a collection of breath-taking sand sculptures.

Velvet Cage:

The Christmas market in the Velvet Cave is more than just a Christmas market. A visit here immerses you in a wonderful Christmas atmosphere you can find nowhere else: iconic underground ambiance, a fairy-tale decor, and, of course, stall after stall of Christmas and gift items, from rustic to luxurious. In short, a great experience, with something for everyone. And all the while, the cave’s atmosphere, with its striking wall paintings and sculptures, brings the Christmas spirit and the old, nigh-forgotten Valkenburg legends to life.
