The best walks and hikes around Cerfontaine

The development of the dams and associated lakes began in the second half of the 20th century with the aim of providing a structural solution to several problems in the region. On the one hand, it involved regulating water flows and limiting flood risks in downstream areas. On the other hand, the project was set up to create a strategic water supply for industrial and domestic use and to generate energy through hydropower plants. The dam itself is part of a network of several dams that together delineate several artificial lakes. This infrastructure is technically designed to store water and release it in a controlled manner depending on rainfall, demand, and ecological requirements. The constructions consist of massive concrete works with adjustable outlets and safety mechanisms to accurately manage the water level. Hydrologically, the system has a major impact on regional water management. The lakes act as a buffer that absorbs peak flows during heavy rainfall, thereby reducing the risk of flooding in downstream rivers such as the Sambre and Meuse. In addition, controlled water management ensures a more stable water supply during dry periods. Ecologically, the construction of the dams has led to the creation of new ecosystems around the artificial lakes. The bodies of water attract various bird species and support diverse flora and fauna. At the same time, management requires attention to the balance between recreational use, water quality, and natural habitats. Today, the area around the L’Eau d’Heure dam has grown into an important recreational center. The lakes are used for water sports, tourism, and relaxation, giving the area an economic function in addition to its original water management task. This makes it a multifunctional landscape where engineering, nature, and recreation come together.

The Plate-Taille Dam is located in southern Belgium in Wallonia, on the border of the provinces of Namur and Hainaut. The dam is situated near the villages of Froidchapelle and Cerfontaine and forms the central element of the Lacs de l’Eau d’Heure lake district, the largest artificial lake complex in the country. This area covers approximately 1800 hectares and consists of several interconnected lakes that together form a unique landscape of open water, wooded hills, and extensive recreational zones. Due to its location between the Ardennes and the Fagne, the area has a varied and gently rolling terrain. The origin of the dam dates back to the 1970s when Belgium faced water management problems. The Sambre River, an important waterway for industry and shipping, experienced highly fluctuating water levels. During dry periods, the water level dropped too low, which had economic consequences. To solve this problem, an ambitious project was launched, including the construction of a series of dams on the Eau d’Heure River and its tributaries. The construction of the Plate-Taille dam began around 1974 and was completed in 1981. As a result of its construction, five lakes were created: * Plate Taille (the largest and deepest) * Eau d’Heure * Falemprise * Ry Jaune * Féronval The construction brought about a major change for the region. Certain areas were submerged, and residents had to relocate. At the same time, this project laid the foundation for a new economic model based on tourism and recreation. The Plate-Taille dam is the largest dam in Belgium and an impressive example of modern hydraulic engineering. The Plate Taille lake itself has a surface area of approximately 350 hectares and is the largest and deepest lake in Belgium. The dam holds back an enormous mass of water and literally forms the heart of the entire lake district. One of the dam's main functions is energy generation through a pumped-storage power plant. * Capacity: ± 140 megawatts * Number of turbines: 4 (reversible) * Type: pumped-storage power plant System Operation The system operates on a clever principle: * During low energy demand, water is pumped to a higher reservoir. * During high energy demand, the water flows back down through turbines, generating electricity. This makes the plant particularly valuable for stabilizing the electricity grid, especially in combination with renewable energy sources such as wind and solar power. Around the dam lies a surprisingly rich nature reserve. The combination of water, forests, and open plains ensures great biodiversity. The landscape is characterized by: * Dense deciduous and coniferous forests * Open grasslands * Reed beds along the banks * Quiet bays and small islands Animals found here include: * Roe deer * Foxes * Waterfowl such as grebes and cormorants * Birds of prey The creation of the lakes has led to new ecosystems where flora and fauna have adapted to the water-rich environment. For someone who enjoys long and challenging hikes, like myself, this area is ideal, and you can easily create routes of several hours here without much crowds. 🚴‍♂️ Cycling and Recreation Besides hiking, the area is also popular with: * Road cyclists (hilly terrain) * Mountain bikers * Families (flat cycling paths around the lakes) There are well-maintained cycling routes that connect the entire lake district. 🚤 Water Sports and Activities The Lacs de l’Eau d’Heure are the center for water sports in Belgium. Possibilities: * Sailing * Kayaking * Windsurfing * Diving (in certain zones) * Swimming Motorized water sports are permitted to a limited extent, which contributes to a relatively calm and natural atmosphere. 🧭 Tourist Facilities The area is highly developed for visitors without losing its natural charm. Key attractions: * Skywalk Plate-Taille – a panoramic tower with views over the entire area * Natura Parc L’Eau d’Heure – adventure park with climbing routes and zipline * Marinas and beach areas * Holiday parks and campsites This makes the area suitable for both day trips and longer stays.

beautiful walk to do with the family

This reservoir is fed by Eau d'Heure and is the oldest artificial water reservoir in the region. Opposite the dam is a small hydroelectric power station. It is also appreciated by all water sports enthusiasts.

This is a truly special view, one that you should stop at briefly during your run. Yachts float on the lake itself, surrounded by forests, and wind turbines float majestically atop the trees.

terrain not too muddy even in the rain

very nice spot not too muddy

Here are 2 benches in an idyllic setting where you have a beautiful view of the lake. Lovely to sit for a while.
