Alpe Adria Trail
A cross-border trail running from the foot of Austria's highest mountain to the Adriatic Sea, through Austria, Slovenia and Italy.
Route overview
The Alpe Adria Trail begins near the Pasterze Glacier at the foot of the Grossglockner, Austria's highest peak, and runs south through Carinthia, across Slovenia's Julian Alps region, and into Italy's Friuli Venezia Giulia, finishing on the Adriatic coast at Muggia near Trieste. It was developed jointly by the three countries' tourism authorities as an official cross-border long-distance trail, divided into 43 official daily stages. The route transitions from high alpine terrain near the Grossglockner through Carinthian lakes and valleys, Slovenian alpine and karst landscapes, and finally Mediterranean coastal terrain in Italy, making it one of the more climatically varied long-distance trails in the Alps. Most hikers walk the trail in regional sections corresponding to each country, though completing the full 43-stage route from glacier to sea is a recognised through-hiking achievement.
