Long Trail Days on the southern GTA

 The trail to Rifugio Barbara Lowrie goes along a road that shows exactly where you have to go.

 From Mon Viso, you can glimpse the lake where the trail descends to.
From the other side of Val Varaita, you can look back at Mon Viso, where the trail has come from and the valley descended.

The GTA crosses valleys, often with 1,000 meters of ascent and descent each day.
