The "mines" of Broux are carved into the hillside: you don't descend significantly to enter them.

The tour takes about 50 minutes and is totally wheel- and push-chair accessible.

You'll enjoy the visit most if you like hearing the intriguing stories: the galleries themselves are certainly imposing but they don't vary hugely in the course of the circuit.

There's only one English-language tour a day. If the timing doesn't suit you, you can borrow an iPod (free) with an English commentary at the reception area and tag along with one of the other tours in French, German or Dutch.

Plan on bringing :
- a sweater or a jacket, as the average temperature inside the Galleries is 10°C.
- walking shoes as the round trip is about 1.5 km.
