  • Grottoes and caves

Discovered in 1904, "La Merveilleuse" is considered one of the most beautiful grottos in Belgium.

The cave remains as nature sculpted it with its many stalactites and stalagmites, each whiter and finer than the other, as well as its many stone formations evoking waterfalls.

Easy access to the inside of the grotto.
