Take the Bozen Süd motorway exit, turn left directly at the exit onto the expressway in the direction of Meran, pass the tunnel and then exit the expressway at the first exit in the direction of Eppan. Keep to the right, then straight ahead on the main road in the direction of Kaltern. After the roundabout at the entrance to Kaltern, go straight ahead until you reach the crossroads. There you turn right, drive uphill to the next sign to Altenburg. Turn left and then about 4 km through the forest. After the bridge, take the next turn to the right, past Gasthof Sonnegghof. A few more meters and you are there.
Have a good trip!
