As we hiked up the switchbacks to Lagazuoi, we passed a series of wartime remains, most in the form of doorways to tunnels. The trail we were now on is a historic World War I soldiers' route. It starts at the Passo Falzarego parking lot, at the base of the mountain, and goes all the way up to Rifugio Lagazuoi. For more info check out Historical remarks on the Frontline Trail.
