AV1 seg. G alt. - Rifugio Lagazuoi to Rifugio Col Gallina via Lagazuoi Tunnels

From Rifugio Lagazuoi, walk around the rifugio to the top station for the gondola. The entrance to the path for the tunnels is right next to the gondola station. You'll follow trails through World War I ruins before entering the first tunnel. 

Descend through the tunnels, taking side trips to check out various viewpoints and rooms. Upon exiting the tunnel, follow the trail downhill until it connects with the larger trail. Turn right onto this trail and continue to follow it downhill.

Just as you are arriving at the parking area for the gondola base station, turn left onto a trail. Then take a right turn to descend toward the road. The trail eventually levels out above the level of the road, but stays parallel until it drops down to the road. 

Upon arriving at the road, you are across the street from Rifugio Col Gallina. You can cross the street and drop directly through the grass, or you can turn left onto the road and enter at the parking lot.
