Branch off R from the standard approach to Col d’Entrèves, heading towards the steep E facing snow slopes of the Tour Ronde. There are a number of ways up this, but there is usually a good track in, weaving its way through the rocks. You head diagonally R at the level of a large block to reach the SE ridge, by the line of least resistance. From there it is predominantly a snowy crest, towards the summit, with the final rocks taken on the R. Descent is the reverse of ascent. Sometimes it is easier to carry on a little further down the ridge, then rappel from Col Freshfield. This is also a possibility in ascent, conditions varying by the season.
