The Halser Ilzschleifen nature reserve is a nature reserve in the Lower Bavarian city of Passau and the municipality of Salzweg in the Passau district .
location
On the northern outskirts of Passau, below the Oberilzmühle reservoir , the Ilz , which comes from the Bavarian Forest , is held up by a gneiss foothills in its course leading south to the Danube . Instead, it makes its way in two meanders through the softer slate layers of the Aicha-Halser secondary pile . This is where the Passau district of Hals is located with the Hals castle ruins .
Since the beginning of the 1990s, efforts have been made to connect the federal highway 12 and the federal highway 85 with the federal highway 3 via a north bypass . A bridge would cross the river north of the Ilz loop. The opponents of this project founded the citizens' initiative Nature ja - Nordtangente no! - Association for the Preservation of Ilz- and Gaißatal e. V.
By ordinance of November 17, 1993, the approximately 91.5 hectare Halser Ilzschleifen nature reserve was created along the course of the river. It extends to the Ilz, its meadows and parts of the accompanying slopes. The river landscape is characterized by a narrow, wooded valley from which sunny rock heads protrude.
