The Pagarì Refuge

A few dozen meters downvalley from San Giacomo di Entracque (1209 m), the track crosses a bridge over the Gesso della Barra torrent.
Head up the Moncolomb Valley, following the same route as the "Pra del Rasur e il Gias sottano del Vei del Bouc" trail, until you reach Gias sottano del Vei del Bouc (1437 m, 1 hour and 10 minutes from San Giacomo).
At this point the dirt road ends in a fork: the route ignores the mule track on the left leading to Lake Vei del Bouc and instead takes the mule track to the right for the Pagarì Refuge. 
The track crosses over the torrent on a wooden footbridge and passes by the Gias Colombo on the right, then proceeds slightly uphill on a mule track that gradually turns into a footpath.
After a long traverse, near a large boulder the track passes a turnoff on the right for the Moncalieri shelter and crosses over the Rio Pantacreus (there is a wooden walkway just uphill from the trail if the stream is too full to wade across). It then quickly passes a mule track in poor condition on the left that leads along the bottom of the Vallone di Moncolomb (this is the old trail to White Lamb Lake, almost completely erased in its upper tract). Beyond the turnoff, the track begins to climb steeply up the side of the valley in a very long stretch of switchbacks to the southwest.
The switchbacks, sometimes fairly tight and stepped, continue through thickets of brush up to the lower Muraion Pass (or Passaggio del Muraion), just beyond which the trail levels off slightly and there is a nice view of the Vallone del Muraion and the top of the valley.
The track then continues on among rocks in open ground, except for a few patches of green alders on the banks of the Rio Pagarì. Once it has crossed over the Rio Pagarì, steep traverses climb up to the turnoff on the left for the Lago Bianco dell'Agnel (White Lamb Lake), which the route passes by. At this point there is another series of long switchbacks that rise up the slope in a southwesterly direction.
The switchbacks gradually become tighter: passing by the trail for the Moncalieri shelter on the right and the one leading to the Pagarì Pass on the left, the trail is now in sight of the Federici Marchesini Refuge al Pagarì (2650 m, 3 hours and 40 minutes from the lower Gias del Vei del Bouc), commonly referred to simply as the Pagarì Refuge, just a short walk away.
