Via Ferrata Degli Alpini and Monte Lagazuoi

From the Col Gallina parking lot, the trail crosses a small bridge over the Rio Lagazuoi and climbs up to a wide mule track. Follow the signposts for "Col dei Bos". Pass near remnants of the Great War, such as former military hospitals and observation post ruins, before reaching the base of the cliff in about twenty minutes. The approach is short and easy.

The Via Ferrata degli Alpini begins with its most challenging section right away: about twenty vertical meters along two cracks on smooth rock with few natural holds, requiring firm pulls on the cable. Once past this initial section, the route becomes easier with well-equipped rock steps, airy traverses with good holds, and short ledges connecting equipped sections. Exposure remains high along virtually the entire route, with a particularly exposed section when rounding a spur about two-thirds of the way up. The final wall, some ten meters high with good holds, leads to the summit plateau and the wooden cross at Col dei Bos. Allow about two hours for this equipped section.

From the summit of Col dei Bos, an unmarked trail heads north toward Forcella Travenanzes (2,507 m). The GPS track is helpful here for finding the correct route. This is also the section where you'll encounter the fewest hikers. At the pass, you will join Trail No. 401, which you will follow to the Lagazuoi Refuge. From the refuge, it takes about 15 minutes to reach the 2,778 m summit of Piccolo Lagazuoi, the highest point of the circuit. From there, you can see the Tofane, the Marmolada, Croda da Lago, and the Sella.

The descent takes place through the Lagazuoi tunnels. The Anticima Tunnel alternates between short horizontal passages and long staircases carved into the rock that are often very steep and equipped with a fixed cable handline. A headlamp and helmet are essential—the interior is dark, water drips from the ceiling, and the high, uneven steps become slippery. Several reconstructed rooms (dormitories, observation posts, and remnants of equipment) offer insight into the living conditions of Italian troops between 1915 and 1917. Allow about an hour in the tunnels, longer if you linger at the historical panels. Bring a warm layer because the temperature remains low inside, even in the middle of summer.

At the exit, you will reach Trail No. 402, which descends in switchbacks toward Passo Falzarego. Before reaching the pass, a small, unmarked trail on the left leads back to the Col Gallina parking lot in about fifteen minutes.
