Rettenbach - Rießriegl - Spannriegl - Koppen

From trail nr 20 after the village Rading in Roßleithen turn right onto the municipal road (trail nr. 463 and 25, Nock) to the Redtenbach cross.

Starting from the Vorderer Rettenbach parking lot, hike a short distance in the direction of the valley. At the fork in the road, turn left and cross the Rettenbach stream onto a forest road. However, you will soon leave this path and change to a forest road - past the Stadler farmhouse until you reach the junction with hiking trail 26 in the direction of Spannriegl, shortly before the Rießriegl farm.
The old Spannriegl farm - today owned by the Austrian Federal Forests - lies idyllically between gnarled fruit trees and a red deer feeding station. Through a short ditch you continue to the "Koppen" and from there on a road with little traffic back to the starting point (partly the Kalkalpen National Park cycle path R31 also runs here).
