Starting in Tiouleve, Montsapey, taking in the Grand Arc Ridge to the Chalet de la Thuile, returning on the lower trails.
The Chalet de la Thuile provides a perfect mid-route coffee stop or even lunch (phone ahead for food).
Great bar/restaurant at the parking in Tiouleve, Montsapey.
Travelling anti-clockwise, on reaching the 2034m mark on the Petit Arc shoulder (after passing the Marret hut). Be sure to drop down past the Chalet de la Platiere. It is tempting to traverse across and take a shortcut. This is 'do-able', but beware, the trail is un-used and disappears into a bog. Therefore not a great 'short-cut'!
