Day 1 — Lago di Braies: lake, forest, and ascent to the high Biella plateau
- 🥾 Start at Lago di Braies, one of the most photogenic lakes in the Dolomites, where the classic northern section of Alta Via 1 begins. It’s worth spending the morning on a short walk along the lakeshore and then heading onto the marked trail no. 1 to Rifugio Biella / Seekofel Hütte. This is already a true mountain day: the forest quickly gives way to rocky slopes and panoramas over the Fanes–Sennes–Braies massif. The active part of the day usually takes about 3.5–5 hours depending on pace and breaks; the distance is roughly about 6–7 km, with an elevation gain of around +900 m. In terms of effort, this is a moderately difficult / hard day, but it suits a regular hiker without special gear because it follows a well-known marked walking trail with no glacier, no ferrata, and no mountaineering sections. All you need are good trekking shoes or boots, water, and enough time. In July at the start of the season, there may still be patches of snow on the upper sections after a cold spring, while in August and September the main concern is starting early because of afternoon thunderstorms. In summer, the Braies valley has traffic regulations in place: during the high season, daytime access by car may require pre-booked parking or use of a shuttle/bus, so it’s best to check the logistics to the trailhead in advance.
