그라페네그‬에서 가장 멋진 ‪20‬개의 천연기념물

트라이젠 강 하구는 오스트리아 니더외스터라이히주 트라이스마우어에 있으며, 기술과 자연이 어떻게 성공적으로 조화를 이룰 수 있는지 보여주는 매혹적인 예입니다. 이곳에서 트라이젠 강은 도나우 강과 합류하지만, 예전에는 지금처럼 목가적이지 않았습니다. 원래 트라이젠 강은 약 7.5km 상류에서 합류했습니다. 1970년대 알텐뵈르트 도나우 수력 발전소 건설로 모든 것이 바뀌었습니다. 발전소를 위해 도나우 강의 수위가 높아졌기 때문에 트라이젠 강은 더 이상 자연적으로 흐를 수 없었을 것입니다. 따라서 완전히 새로운 강바닥을 파야 했습니다.

A beautiful wine-growing region crisscrossed by numerous hiking trails. Here, up to the Danube lookout point, you can hike the Great Tullnerfeld Circular Trail 475/675, the Waldviertel Long-Distance Hiking Trail 606, or the Mariazell Trail 06 – all at the same time!

At approximately 12.5 kilometers, the Altenwörth Fish Bypass is the longest of its kind in Austria and was built between 2019 and 2022 as part of the LIFE Network Danube Plus project. It allows fish such as huchen, schied, and zingel to bypass the Altenwörth Danube power plant and provides a continuous connection to the tributaries, the Kamp and Krems. The near-naturally designed bypass stream, with shallow water zones, gravel banks, and deadwood, also creates new habitats for numerous animal and plant species. The facility is also of interest to cyclists: Along the Danube and its adjacent waterways, natural paths offer views of renaturalized landscapes, small bays, and ecologically valuable rest areas. It is a successful example of how flood protection, energy use, and biodiversity can be reconciled.

One of Austria's longest fish bypasses was created between Altenwörth and Greifenstein as part of the "LIFE Network Danube Plus" project. The approximately 12.5-kilometer-long, near-naturally designed bypass stream allows fish such as huchen, zebrafish, and schied to migrate freely along the Danube and connects important habitats in the tributaries of the Kamp and Krems. Between 2019 and 2022, approximately 34 hectares of new aquatic areas were created, featuring shallow water zones, gravel banks, and deadwood areas – also for kingfishers, otters, and other protected species. In addition to its ecological benefits, the area is now also attractive to recreational travelers: Along the waterway corridor, natural banks, small bays, and viewpoints invite visitors to linger – a successful example of the combination of nature conservation, water development, and sustainable tourism.

From here you can quickly reach the summit cross of the Manhartsberg!
