Alta Via 4 is a high route located in the Italian Dolomites between Innichen in the north and Pieve di Cadore in the south.

[1] The trail is well marked with red and white paint splashes, cairns, and occasional dark blue triangular symbols containing the number '4'.

Most hikers walk the trail from north to south, which is the way the route is described in the most guidebooks.

The hike goes around Tre Cime di Lavaredo, which are probably one of the best-known mountain groups in the Dolomites.

Then it continues around high altitude Lake Sorapiss, and finally goes through mountain ridge Antelao.
