Seiser Alm, (ItalianAlpe di Siusi) is the largest high altitude Alpinemeadow in Europe. Located in Italy‘s South Tyrol province in the Dolomites mountain range, it is a major tourist attraction, known for skiing and hiking.

And from Südtirol.info

365 Alpine pastures, huts and mountain farmsteads scattered over an area the size of 8,000 football pitches: the Alpe di Siusi/Seiser Alm is Europe’s vastest expanse of high Alpine pastureland and a giant open air arena for young and old.

And over 2000 meters above sea level, or 6500 ft.

Ahhhhhhhh….
