Starting from Castellar (signpost #400 near the cemetery) , we first ascended along a steep paved road to signpost #401 where we forked right steeply, leaving the paved road. It was part of the GR51 trail and after passing some houses we started to climb in the woods south of  the Roc de l’Ormea massif. We reached signpost # 716 and took the left-hand trail to Col du Berceau. The ascent was steep all the way, with a lot of moving rocks on the trail. We remembered that it was nevertheless easier to climb than to descend.

At Col du Berceau (1080 m) we forked right (east) along an unmarked but clear trail and climbed to Cime de Restaud with a cairn and a small painted metal cross on the summit. The super panorama was 360°, and we were just a bit higher than the Roc de l’Ormea summit. Many hikers climb both summits as they can be easily reached from the col.
