In the Biodiversum nature and forest center, visitors can expect interactive exhibitions on bird and nature conservation, as well as biodiversity. The futuristically designed Biodiversum nature conservation center was built on an artificially created island and is located at the foot of the vineyards in the "Haff Réimech" nature reserve. The ground floor presents, among other things, the history of the nature reserve and the underwater world. The upper floor introduces visitors to the world of birds and plants, other nature reserves in Luxembourg, environmental protection, and sustainability. The visit can be wonderfully combined with an ornithological walk through the nature reserve, which is valued for its great diversity of bird species and its rich flora and fauna. Adjacent gravel pits provide cooling in the summer.

🚧 **Barrage du Lac du Mirgenbach – The Technical Heart of the Lake** At the southern end of **Lac du Mirgenbach** is the **dam (barrage)**, which serves to regulate the water and cool the nearby **Cattenom Nuclear Power Plant**. The facility is not open to the public, but is easily visible from the paths around the lake. 🌊 The dam marks the transition between technology and nature: Here, the water flows in controlled channels, creating an exciting interplay of industrial function and scenic tranquility. **Tip:** Those who walk the circular path around the lake have a good view of the dam from the eastern shore – particularly interesting for technology enthusiasts and landscape photographers.

A magnificent walk to do, birds to observe, a very well maintained site. You can do this walk with your family, it will allow your children to discover the beauty of nature and many species of birds. You will be in a different world. At the end of the walk, you can eat at the "Chalet", a very welcoming bar-restaurant. An exotic site.

Fantastic cycle path. Nice restaurant with a large terrace. You want to stay longer in the park and enjoy everything. From here along the Alzette to Luxembourg City. In Lux-Grund you can take a lift up to the upper town. I do this route at least once or twice a year
