Start / Finish: Merkersdorf
Start / Finish: Merkersdorf
From the Kaja parking lot, the trail leads through the wild and romantic Kaja valley around the Kaja ruins. In spring, colorful spring flowers line the stream, while in summer the gorge, overgrown with ferns and mosses, exudes a pleasant coolness.
Sturdy footwear
Starting at the Kaja parking lot, the trail leads over the bridge at the entrance to the Kaja ruins and into the Kaja Valley. Rare crayfish live in the Kaja Stream, and otters can be seen here foraging for food. At the first bridge, the trail branches off to the left from the forest road and runs along the Merkersdorfer Bach. The castle ruins are now visible from the rear. After crossing two bridges, you reach a meadow, beyond which lies the Kaja parking lot once again.
