Punta di Saas, W flank.
From Cresta biwak. this is the easiest flank of Punta di Saas, you can easy scramble to the pass on the left of the summit(Camposecco Pass) and then reach the top in a few minutes.
This is anyhow a remote area and to get here you have to cover a long trail, from 1500 to 2000 meters of elevation gain if you start from Switzerland or from Italy.
