This hike leads you from the centre of Nalles to castle Katzenzungen, where the oldest and largest grapevine in the world is located.
From Nalles you go north in direction to the Stachelburg along the bridge of the Nalserbach to the path no. 2. The steep incline (way no. 2) runs up to the ruin of Pfeffersburg in Unterkasatsch, above Nalles. You walk the secondary road to Prissiano or you take the way no. 2, which leads through apple trees and then on a forest path. Both ways lead you to the castle Katzenzungen. Take the path no. 2 back to Nalles.
Alternative, you can take the bus (line 248) from Prissiano to Nalles.
