If you are shunning the lifts then leave early to avoid the skiers coming past you - you will be skinning up the pistes. There are no particular navigational difficulties and a number of possible lines, all of which take you to the frontier at the Splügenpas at 2114m. It is an easy descent the far side, down to the Italian lake of Lago di Montespluga at 1900m, above the ski resort of Madesimo. You will probably see tourers coming up from below. It is worth being early as you have nearly 800m of ascent ahead of you, predominantly S facing. Follow the obvious valley and other tourers to the N, then NW, followed by NE, to avoid steep ground, passing round the back of the well placed Suretta bivi hut. You then take a descending traverse down to the Suretta Pass at 2579m.

It is slightly complex terrain the far side, but broadly you descend SE, over the Lago di Ghiachiato, then pick a line NE, down to the easy valley below. Go E then NE to the hamlet of Alp Niemet. From there it is an obvious track which goes to the main valley floor, just below Innerferrera. It is well shaded so hopefully you will be able to do most of this on snow.
