“The Upper Sûre Nature Park is not a typical park with an enclosure,” explains ecologist Patrick Thommes. “It is an entire region which combines work and recreation in an ecologically useful way.” Set amid breathtakingly beautiful countryside, the park boasts deep valleys, wet meadows, steep forested slopes and a high farmland plateau. At its centre is a reservoir supplying around 70 per cent of Luxembourg households with drinking water. Visitors can discover more about this by taking a guided nature tour via a solar-powered boat.
