Kerst in MergelRijk is a captivating underground Christmas experience set within the ancient marl caves of Valkenburg, offering a truly one-of-a-kind holiday attraction that enchants visitors of all ages. Part of the broader Christmas Town Valkenburg — awarded Best Christmas Market in the Netherlands and Best Christmas Parade in Europe in 2024 — MergelRijk stands out as a highlight among the city's celebrated underground festivities. Deep inside the warmly lit marl stone corridors, visitors are treated to an extraordinary 25-meter-long miniature village display, where intricately crafted Christmas scenes bring the holiday spirit to life on a grand scale. The Christmas story is told in imaginative detail through both large-scale and miniature installations, including vivid marl sculptures and immersive 3D paintings that transport guests into a festive storybook world. The glowing cave passages create an intimate, cozy atmosphere that feels entirely removed from the outside world, making it a magical escape for families, couples, and solo travelers alike. The experience is designed to engage all the senses — from the warm amber glow of hundreds of lights reflecting off the golden marl walls to the charming details of the miniature village inhabitants waiting to be discovered around every corner. MergelRijk is consistently recommended as a family-friendly must-do within Kerststad Valkenburg, complementing the city's other underground markets such as the Gemeentegrot and Fluweelengrot Christmas markets.
