The Völser Aicha farm trail begins at Castle Prösels. Follow the signposts for “Oachner Höfeweg”, going past a few wine cellars and past numerous farms. Through mixed and chestnut woods, the trail leads high above the Isarco Valley and on to Unteraicha. Continue the tour until the small village of St. Kathrein with its little church. Return by bus no. 176 or on foot on the same path.
