The day begins in the Pudeto sector to take the catamaran that will leave us at Paine Grande Refuge, from here begins the walk to Valle Gray bordering the mountains and the Lakes. The type of terrain in some sections presents loose stones and mud. The level of demand of this walk is high since we face constant ascents with a high degree of inclination and abrupt descents. It is certainly not an easy path, but the view that awaits us towards the end will make any effort rewarded.
