Alta Via 1 stages and daily distances

Alta Via 1 is a rifugio route, and the huts decide the days. There is nothing between them: no villages, no shops, and above 2,000 m very little reliable water outside the huts themselves, so most walkers fill up at breakfast and again at lunch. Distances between rifugi are short by valley standards, and the opening leg from Lago di Braies to Rifugio Biella is only 7 km, because the huts sit where the terrain allows, on saddles and shelves rather than at neat intervals. Beds are limited and half-board is the norm.

Six and a half thousand metres of climb over 120 km is a punishing ratio, and it explains stages that look absurd on paper. A day of 11 km can hold 900 m up and 900 m down on scree and rock. Rifugio Coldai to Rifugio Tissi is 6 km and still a proper half-day once you have crossed the ridge and the broken ground beneath the Civetta wall. The high point of 2,752 m falls in the Lagazuoi section, and altitude thins your pace as much as gradient does.

The route reads as three parts. The northern opening from Lago di Braies climbs quickly to Rifugio Biella and crosses the Fanes plateau: wide, pale and comparatively kind. The middle, from Rifugio Fanes to Rifugio Lagazuoi and on to Rifugio Nuvolau, is war-tunnel and via ferrata country, the most photographed and the most exposed. The southern half, past Rifugio Coldai and Rifugio Tissi below Civetta, is rougher and quieter, before the long descent out of the mountains towards Belluno.

The classic error is booking flights on the assumption that 11 km days are half-days. They are not. The second is finishing in the wrong place: the final descent to Belluno is long and unrewarding, and many walkers stop earlier and take a bus, which is worth deciding in advance rather than at three in the afternoon on the last day. The third is arriving without a via ferrata set for the aided sections and then improvising on the cable.
