Guided Tours of the Zonneberg Caves| Maastricht Underground

Maastricht

Do you dare go underground? Not afraid of the dark? Go exploring the Zonneberg Caves. No light, no sound, no smell, no radiation, no pollution, no mobile phone signal, no idea of time…

Please note! For the Zonneberg Caves, we strongly recommend on buying tickets in advance. This is also possible via this website. On the spot, tours may be sold out and only card payment is accepted.

Your guide will make sure you don't get lost in the man-made galleries, which once measured 230 km in total and measure around 80 km today. Almost 50,000 Maastricht residents sheltered in the expensive cave network during the Second World War. An evacuation area with electric lightning, a public address system, a bakery, chapels, toilets, a small hospital, water pumps and many more! All facilities were constructed underground, though never put into fill use. Remnants of them can still be seen in the Zonneberg Caves. For more information, click here.
