Alta Via 3 delle Dolomiti

Alta Via 3 delle Dolomiti — the trail guide

The Alta Via 3 delle Dolomiti is a 103.5 km trek in Italy, typically walked in 5–7 days, with 8476 m of total ascent. It rates Hard on our published rubric (82 m of gain per km, topping out at 2642 m).

Alta Via 3, nicknamed the 'Sentiero del Camoscio' (Chamois Route), is the wildest of the Dolomites' classic high traverses, running roughly 100 km south from Villabassa in the Val Pusteria to Longarone above the Piave. Quieter and more demanding than Alta Via 1 or 2, it links remote rifugi across the Cristallo, Sorapiss and Marmarole groups, with exposed, cable-protected passages and long days at altitude.
