  • If you choose to go to your right, you will first cross the Nisramont dam.
  • The path follows the lake, crossing two smaller dams.
  • Continue along the lake for 7 km. The path sometimes goes up the bank, sometimes down the bank.
  • Once at the confluent of the two Ourthe rivers, cross over to the opposite bank and return to your starting point, enjoying the flora and fauna as you do so.

A walker's guide to Wallonia

If you were to draw a straight line on an atlas northward from the Massif Central in France to the North Pole, the only area of high ground the line crosses is the Ardennes, shared between Belgium, Luxembourg and Germany – but mainly belonging to Wallonia, the southern part of Belgium!
