Welcome to the best Cave of Valkenburg recommended by worldwide visitors!

At MergelRijk you’ll discover the most beautiful Cave in Valkenburg and you really experience everything about caves and marl. The rich history of the marl caves comes to life along the way through beautiful marl and sand sculptures.
You will learn how the marl layer was created about 65 million years ago and you will experience how the block breakers removed the marl from the mountain and thus the marl caves were created. You can see what the marl and caves were used for in the past and for which the special rock is still used. One of the highlights that can be seen is a life-size sculpture of the famous painting the ‘Nachtwacht’, carved entirely from marlstone.
But there isn’t only a lot to see, there is also plenty to do in MegelRijk! You can make your own souvenir from a real block of marl. You can leave your name in one of the walls in a dark part of the cave and you can have your picture taken with the latest 3D cave paintings. All this is only possible at MergelRijk! It should be on your must-do list when you’re visiting Limburg

New: go back 70 million years in time in the Mosaquarium (summer 2024) and take the best photos with the 3D cave paintings.

At MergelRijk you can see spectacular 3D cave paintings on the walls, ceilings and floors. These cave paintings are unique in the world. The 3D paintings can only be seen clearly through a camera or telephone and are best experienced by taking a photo with them. The Mosaquarium will be open from summer 2024! As if you were walking on the seabed, as it was here 70 million years ago. In this new underwater world you come face to face with the Mosasaurus.

MergelRijk is a cave for adults, also very nice for children!

MergelRijk is an underground paradise for children where they can experience and do a lot, especially made for children . With a treasure hunt book they go through the cave and discover, for example, a jaw of a mosasaur in the fossil museum. They can work on a marl block in the cave workshop, look for fossils in the marl quarry and enjoy a film of the famous Dutch sand wizard. A real DinoWorld has been made especially for children in MergelRijk, in which you come face to face with dinosaurs!
A visit with children takes about 1.5 hours.
