From Reschen go north towards the Austrian border. Just 500 m before the valley station of the Bergkastel cable car (Nauders), take a sharp right along a fairly steep gravel road to the mountain station. Stop for refreshments in the Bergkastel mountain restaurant. Here starts the most beautiful part of the tour: return to the ascent path to the Bergkastelalpe and continue to the left to the high moorland of Plamortböden and the anti-tank barrages that are also well known across the border. Use here the forest road or the beautifully laid out trails (S2). After passing the barriers, the view opens up over the Vinschgau Valley with its unique lake landscape from the vantage point on the rock. With a breathtaking view descend to Reschen: on the technical and partly more demanding Bunker Trail (S2), with the subsequent Etsch Trail (S1) leading into the forest, or on the forest road to Reschen. Once back there, enjoy a typical aperitif.
