From the Avérole Hut you are following steep SW facing slopes, to the L in ascent of the Ruisseau de Veilet. When I was there in a lean snow year we carried skis for a couple of hours, as the sun had completely stripped it. When snow-covered it may be icy due to the melt/freeze action of the afternoon sun, so ski crampons may be required. There are odd steep sections but broadly you are taking the line of least resistance up the slope, joining in with your tracks that you descended a couple of days earlier in the top section. If for whatever reason you were unable to top out on Albaron, or it was misty when you were there with no views, it is a short detour to the summit. But this isn’t needed, as once you have reached the shoulder below the summit at about 3460m, you can descend from there.

Head NW to the flat Col du Grand Fond at 3345m, then continue in the same direction on steepening ground, taking the R branch of the Glacier Superior du Vallonet. This weaves around with odd steeper sections, but it links nicely, often in powder, due to its enclosed and N aspect, opening out to an apron of easier slopes at about 2500m, then down onto the pistes to Bonneval.
