Grottes de Rochefort

Rochefort is the base for visiting the grottos which were carved out by the waters of the Lomme thousands of years ago; they were discovered in 1865 and investigated throughout 1870. They rank almost equal to the grottoes of Han-sur-Lesse as far as their beauty and the number of visitors is concerned. Their stalactite formations are bizarre, the temperature of 8°C/46°F is less than that in Han so that warm clothing is necessary for the visit which takes about an hour.
