The Italian Dolomites - Alta Via 1 Map

The Alta Via 1 (AV1) is a classic long-distance hiking route through Italy’s UNESCO-listed Dolomites, covering approximately 125 km (77 miles) from Lago di Braies to La Pissa. Crossing 18 high mountain passes with around 6,500 metres (21,300 ft) of cumulative ascent and descent, it offers a superb all-round introduction to hiking in the region. The trek is typically completed hut-to-hut, staying in mountain refuges (mainly dormitory-style, with limited private rooms available subject to availability).

The Alta Via 1 is a challenging trek with significant daily ascents and descents. It requires good fitness and stamina. Guided treks offer the support of a guide, while self-guided options require strong navigation skills and self-sufficiency.

TMB TREK GRADING - GRADE 3: DIFFICULT

Treks are graded 1-4 (low to high) with 1 being relatively easy and 4 being the toughest. The Alta Via 1is a grade 3 trek. Described as difficult, the Alta Via 1 is hard and physically demanding. You will be travelling over rugged and mountainous terrain with a sustained amount of ascent and descent on a daily basis.

The trek is best done from mid-June to mid-September, when the mountain passes are snow-free and accommodations are open. Early-season treks (June) may have some lingering snow, while late-season treks (September) offer quieter trails and cooler weather.
