Between Unteralling in the southeast and Eilsbrunn in the northwest, the Schwarze Laber loop leads through the district of Sinzing over the Jura slopes and along the Schwarze Laber. Level and calm passages give way to steep and demanding ascents. This constitutes the special charm of this loop trail

In parts the Schwarze Laber loop climbs up the steep Jura slopes on rocky or leaf-covered ground, and then along the edge of the slopes through light mixed forests. In some places the forest gives way for a view of the idyllically meandering Schwarze Laber, e.g. at the Hohe Wand, a marked viewpoint north of Alling. In the valley, where the trail follows the river bank, lined with alders and willows, the hiker is entertained by the light-and-shadow-play of the sun rays which pierce the river through the foliage. Shortly before Eilsbrunn, the route offers a special treat at the Pfalzbauernberg: Here the trail leads across a dry grassland landscape framed with impressive boulder formations which are typical for the Jura. This area is one of the most beautiful in the whole of the Bavarian Jura.

Apart from geological attractions the route also offers cultural features. The road from Alling in eastern direction leads along the former railway tracks of the "Allinger Bockerl" (a small steam locomotive).The current bicycle and hiking trail of the Schwarze Laber follows the former railway tracks. This local railway was initiated by the publisher Friedrich Pustet and other entrepreneurs. Between 1875 and 1985 it transported goods on its length of 4,14 kilometers and, until 1965, persons, too, between Sinzing and Alling. Almost no one today is aware of the fact that in former times the Laber valley was not only a popular place for excursions from Regenburg, but also that the water resources and brown coal mines there made it a location of flourishing industrial and crafts businesses. Some of the mills and sawmills are still in action even today, and the building of the former paper manufacturing factory of the Pustet brothers is also still in existence.

The trail through the valley leads past the Schlossberg near Bruckdorf, where there are only a few remnants of a former castle. The trail is also part of the so-called "Burgensteig" (castle trail), and information boards illustrate the importance of the locations.
