A set of underground tunnels and fortifications, not so suitable for kids and people with mobility and claustrophobia issues. So arm yourself with a brochure or a guide of this cave area but do watch out for the steep and slippery steps. Use the help of the hand rails to explore the ancient caves carved out of rock with an adventurous mind. There are also the Casemates du Bock which are bigger.
