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.

The region around Bertogne is rich in natural beauty. A particularly striking site is Le Hérou Rock Formation, known for its steep rocks and spectacular views of the Ourthe River. Another notable spot is the View of the Confluence of the Two Ourthes, where the western and eastern Ourthe rivers meet at the Barrage de Nisramont reservoir.
Yes, the area combines natural beauty with historical significance. Le Cheslé Celtic Fortified Settlement is a remarkable site. It was once a fortified Celtic settlement, featuring a double wall made of earth, slate, and wood, stretching over 1,750 meters. Excavations and reconstructions have been ongoing since 1960, offering a glimpse into ancient history amidst the natural landscape.
The natural monuments offer diverse and impressive views. From Le Hérou Rock Formation and the related Hérou Rocks - François Rémy Viewpoint, you'll get authentic landscapes of the Ourthe River and its wooded meanders. The View of the Confluence of the Two Ourthes provides scenic vistas of the Barrage de Nisramont reservoir and the surrounding forests. The Western Ourthe Viewpoint also offers beautiful river and landscape views.
Yes, some natural monuments are suitable for families. The View of the Confluence of the Two Ourthes is considered family-friendly. While some trails around sites like Le Hérou Rock Formation can be challenging, there are often easier paths or viewpoints accessible for a family outing. The Fairy Valley Achouffe, with its whimsical atmosphere, is also a charming spot for families.
The Bertogne region, situated within the Parc naturel des Deux Ourthes, is ideal for various outdoor activities. You can find extensive networks of marked walking, cycling, and mountain biking routes. For hiking, explore trails like the 'Western Ourthe Viewpoint – Dam on the Ourthe River loop' or the 'Gravel in the woods – Castor Dam loop'. You can find more details on these and other routes in the Hiking around Bertogne guide, the MTB Trails around Bertogne guide, and the Running Trails around Bertogne guide.
The difficulty of trails varies. Sites like Le Hérou Rock Formation are known for challenging trails due to steep terrain, with some paths described as 'almost via ferrata'. Other viewpoints, such as the View of the Confluence of the Two Ourthes, are more intermediate or family-friendly. The circular hike around Nisramont Lake also features challenging sections with climbs and descents, so appropriate footwear is recommended.
The region, particularly within the Natura 2000 network (which includes Le Hérou Rock Formation) and the Parc naturel des Deux Ourthes, is rich in biodiversity. You can expect to see diverse flora in the vast forests, wetlands, and along the rivers. The Fairy Valley Achouffe is especially known for its colorful mushrooms. The preserved natural setting provides opportunities to observe local fauna, though specific sightings depend on the season and luck.
The natural monuments around Bertogne can be enjoyed throughout the year, but each season offers a different experience. Spring brings lush greenery and blooming flora, while summer is ideal for longer hikes and water activities around Nisramont Lake. Autumn is particularly picturesque, with vibrant fall foliage, as noted by visitors enjoying the 'autumn sun' at sites like Le Cheslé Celtic Fortified Settlement. Winter offers a tranquil, often snow-covered landscape for those prepared for colder conditions.
While the main highlights are well-known, the extensive network of trails within the Parc naturel des Deux Ourthes means there are many opportunities to discover serene and less-trafficked spots. The region's rolling landscapes and deeply incised valleys often hide panoramic views. Exploring the various hiking routes, such as those found in the Hiking around Bertogne guide, can lead you to quiet places to relax and enjoy the tranquility away from the main tourist paths.
Given the varied terrain and potential for challenging trails, it's advisable to bring appropriate footwear, especially sturdy hiking boots. Depending on the season, layers of clothing are recommended, along with rain gear. Water and snacks are essential, particularly for longer routes. A map or GPS device (like komoot) is helpful for navigation, and binoculars can enhance wildlife viewing. Don't forget your camera to capture the stunning views!
Generally, dogs are welcome on trails and in natural areas in the Ardennes, but it's always best to keep them on a leash to protect wildlife and ensure the safety of other visitors. Specific rules might apply in certain protected zones or on private land, so look for signage. Many outdoor enthusiasts enjoy exploring the region's paths with their canine companions.
Bertogne is situated within the heart of the Parc naturel des Deux Ourthes, a vast protected area renowned for its wild landscapes. The park itself is a significant natural monument, encompassing diverse terrain including plateaus, deeply incised valleys, dense forests, and wetlands. Many of the individual natural monuments, such as the Ourthe River viewpoints and rock formations, are integral parts of this larger park, offering extensive networks of marked routes for exploration.
