Once on the glacier walk south-east for 5 - 10 minutes and then, once above the steep icy section at the bottom of the glacier, turn due south and head directly for a small col on the Petite Verte's North-west ridge. Just below the col is a bergschrund (which could be quite wide in a hot summer) and a short 45 degree snow slope, which can feel quite exposed in icy conditions.

Once at the col, make an exposed snow traverse just to the left of the crest of the North-west ridge to a lovely snow arête. Climb this and then do another exposed traverse on the north side of the ridge crest before rejoining the ridge via a short 45 degree snow slope.

Once on the ridge scramble on the crest easily for 20 metres then drop off right onto an exposed platform with an amazing view of the Petit Dru, pass through a little gap and walk to the foot of a 10 metre wall. Climb the wall (3c) and move left at the top to a belay on in-situ slings and then scramble easily for 20 more metres to reach the Petite Verte summit. Soak in the wonderful high mountain ambience and take plenty of photos!

To descend, reverse the route, abseiling the 10 metre wall and downclimbing the rest.
