High Above the Clouds: Navigating the Alta Via 1 Across the Italian Dolomites

Declared a UNESCO World Heritage site for their exceptional natural beauty and distinctive geology, the Dolomites of northeastern Italy rise from sub-alpine pastures like petrified coral castles. 250 million years ago, these peaks were indeed coral reefs submerged beneath the tropical Tethys Ocean; today, their vertical pale dolomite walls glow with the fiery phenomena known as enrosadira—the alpine glow that turns the mountains copper, coral, and violet at dusk.

The Alta Via 1 (High Route 1) is the quintessential Dolomite traverse, winding 120 kilometers from the pristine mirror of Lago di Braies in South Tyrol southward to the historic town of Belluno in the Veneto.

Walking Through History: The Great War Mountain Front

Between 1915 and 1917, these sublime mountain passes formed one of the most brutal high-altitude battlefields of World War I. Italian Alpini and Austro-Hungarian Kaiserjager troops carved tunnel networks, ammunition hoists, and iron-rung cliff walkways through the solid rock.

Traversing the Lagazuoi massif, hikers can explore restored subterranean mine galleries and walk along cliff-hanging trenches. The route seamlessly combines world-class mountaineering with profound historical contemplation.

The Culture of the Alpine Rifugio

What sets the Alta Via 1 apart from backcountry wilderness treks is its exceptional mountain hut (rifugio) system. Perched on sheer precipices at elevations exceeding 2,500 meters, huts like Rifugio Lagazuoi, Rifugio Nuvolau, and Rifugio Tissi offer warm down duvets, hot showers, and three-course Ladin dinners featuring polenta with wild mushrooms, venison ragu, and freshly baked strudel.
