Located just out of the small town of Furfooz is this 4km circular walk incorporating Roman remains and scenic views. The path quickly climbs to a partially reconstructed Roman Bath at the site of a spring and a fortess structure called a Donjon. The sites are clearly numbered and you follow a marked path but there is no English. There are two splendid viewpoints overlooking the Lesse River including a staircase cut into the stone leading to a lovely Grotto. After passing a medieval wall you descend towards the valley floor passing many caves where bats reside. After following the river a short way you return back to the valley and past a massive cave which again is a home to bats and not accessable because of the steep slope.
