Cross-border hike to the Heidelberger cabin in Val Fenga (Fimbatal).

Begin your route from Samnaun Dorf through Val Masauna and past "at the waterfalls". Since the Sulnerferner has strongly withdrawn, the volume of the waterfalls has also become smaller. You continue by steeply ascending over the Zeblas pastures to Zeblasjoch, where you cross the state border to Austria. After a slight descent, the trail climbs again to Fuorcla Val Gronda, the highest point of the hike. A detour to Piz Val Gronda with the mountain station of the new cable car (operated only in winter) and the 360° panoramic view is worthwhile. From now on, we hike back on Swiss territory down to the Heidelberger cabin, always with Fluchthorn in view. The German cabin on Swiss ground is kept by an Austrian (mid-June to mid-September). The foundations of prehistoric alpine cabins, which were excavated in 2007, are located just above the Heidelberger cabin. After a rest, you continue along the path leading  through the Fimba valley to Gampen Alp (A), where another steep climb back to Zeblasjoch awaits you. Take the same path back to return to Samnaun Dorf.
