Hiking tour Starting from Ottenstein reservoir, parking lot
Hiking route no. 80 has the meaningful title "Nature, Energy, Power." No wonder, since it begins at the Ottenstein reservoir, where a lot of energy is produced, and leads through a wonderful landscape. For some time now, the reservoir can be crossed on foot. Above the mighty dam, a breathtaking wood-steel bridge has been built. The curved footbridge is not only an optical enhancement but also serves an important function: it connects the lake restaurant and boat rental on the south shore with the north shore's Ottenstein Castle and the sailing and surfing school almost directly. At the same time, the path provides access to the natural bathing spots at the lake.
The Ottenstein reservoir, the third and largest in the region alongside Dobra and Thurnberg, is 14 km long and almost reaches the Cistercian abbey Zwettl. It impresses with its fjord-like, forested shores and bays; it is no coincidence that this part is called the Scandinavia of the Waldviertel. The entire region around the reservoirs has been declared a landscape protection area. Along the Nature Energy Power circular hiking route, you can enjoy peace and beauty of the untouched Waldviertel landscape for a total of 11.5 km. Especially charming and relaxing is the section along the shore with a view of the Lichtenfels ruin. Rest areas invite you to a leisurely picnic in the open air. If you want, you can take an immediate plunge into the cool water on hot summer days – a refreshing cool-down after any hike. There is a diverse range of leisure activities directly at the lake: boat rental, boat restaurant, campsite, surfing and sailing school, etc. Whether you hike or swim immediately in the lake, the Ottenstein reservoir is definitely worth a trip or detour!
