In Germany, 60 km from Krásná Lípa in the direction of Gorlitz, there is a flooded sand quarry. There is a 16 km long road around the lake (14 km with perfect asfalt). Possibility of swimming (beautiful sandy beach) and snacks along the way. I recommend it for families with children. The path is suitable for skaters with strollers. Parking (see map) price 2-6Eur.
