This is the way:
Please drive in direction of the center of Altaussee. At a crossing (after the bakery on the left hand side) turn right, direction to Hotel Seevilla. Pass Seevilla on the right (so that the lake is on your left) and immediately after Seevilla turn right over a small bridge. After 100m please find the entrance and the label "Puchen 326" on the left hand side.
