The glow of the yellow marl stone gives the cozy city of Valkenburg a warm ambiance throughout the year. The marl stone is both underground in the many caves and above ground, integrated into beautiful buildings. But it’s not only the marl that makes Valkenburg such a vibrant city. The castles, including the only mountain castle in the Netherlands, a coal mine, museums, theme parks, cable cars, a thermal pool located on the Cauberg and the casino make that you’ll never be bored. Sociable shops, restaurants, (heated) terraces, the river de Geul and historic buildings, characterize the street view of Valkenburg. Just outside of Valkenburg in the picturesque villages around the city, you’ll find a lot of beautiful nature.
