By the way, the Silvretta High Alpine Road is also great for cycling uphill on a racing bike. From the Silvretta-Bielerhöhe, you can start fantastic high-altitude hikes with magnificent mountain panoramas, such as Piz Buin (3,312 m), the highest mountain in Vorarlberg. The Verwall Natura 2000 European protected area, a nature reserve in Austria set in an idyllic high moor landscape, with the Wiegensee lake, is definitely worth a visit. The Lünersee, one of the largest natural lakes in the Eastern Alps, also invites you to linger by and in the turquoise waters at an altitude of 1,970 m, especially in summer.
