It is a panoramic viewpoint which overlooks the Hérou Felsen and the Ourthe. It is named after François Rémy, French doctor, former director of UNICEF for the Middle East and North Africa. He was also a hiker and explorer passionate about the Ardennes region. He discovered this viewpoint in 1977 and was amazed by its beauty. He wrote in his diary: "I have never seen such a splendid view of the Ardennes. It is like a painting of nature, with the rocks, the river, the forest and the sky. It is a place of peace and harmony, where we feel the presence of God". What do you think ? Do you agree ?

The highlight is rather on an offshoot of Le Hérou called François Rémy. Le Hérou is another 5 minutes further.

The Nisramont dam complex was built in 1958. The intention was actually to create a much larger lake with a dam at the Celtic site of Le Cheslé. Not coincidentally there, because as we will notice during the next stage on the Escapardenne Eislek Trail, the Ourthe is strongly incised here and it is therefore technically ideal to dam even further downstream from that deep incision. The storage capacity is expected to be up to 250 million m³. The current Nisramont dam was therefore built as a temporary project, but more than 50 years later it is still standing.
