Maastricht is a very old city. One of the ways to experience its history is by taking a tour underground. There are three types of tours offered: Caves, Casemates, and Fortress. All stand-alone tours are €5,75 for adults and €4,75 for children. Tickets can be bought at the VVV, online or at the starting point of the tours (provided on the website). There is currently a Minicard at the VVV which gives you 10% discount.
There are two caves that can be toured: North Cave (Grotten Noord) and Zonneberg Caves (Grotten Zonneberg). Both tours last about 1 hour. These caves were made by mining marlstone, just like the Valkenburg caves. English tours are given in the North Caves (all year round) and in the Zonneberg caves (6 Jul – 25 Aug). You can always join a Dutch tour if you like.
Maastricht was once a fortress city. This tour explores the underground passageways that connects the different parts of the casemates surrounding the old city. The tour takes about 1 hour and is usually only provided in Dutch. The guides were nice enough to give us a bit of history in English before the tour started though.
Fort Sint Peter dates from the 1700s. The fort was recently restored and the tour takes you through the fort to it’s top, where you get a great view of the city. The tour lasts 1 hour and is usually only provided in Dutch.
