From the Walchsee information office, head north along the Schwemm river to Rettenschöss and then take the second right towards Wildbichl.
In Wildbichl turn right and shortly before the border crossing turn left, always uphill to Erlerberg. Follow the signs to the Spitzsteinhaus with a wonderful view.
From the Spitzsteinhaus take the same way back to the crossroads and here turn right, steep and winding to Erl. In Erl turn left past the Passionsspielhaus and left at the customs house to Niederndorf. From Niederndorf follow the main road until shortly before Fuchsanger, here again left via Pötting to Walchsee.
