Take the now tarmac road to the large car park at Fonts de Cervières.
(S/E) Cross the hamlet via the track and the bridge over the Pierre Rouge torrent.
(1) Leave theGR®58(Tour du Queyras) trail climbing up to the Col de Péas on your right and take the sameGR® trail on your left towards the Col de Malrif. Continue along this well-marked red and white trail until you reach a large plateau.
(2) Then begin the steep climb, first through alpine pastures and then schist, which joins the ridge above the Lacs de Malrif lakes and then the Col du Petit Malrif pass.
(3) Continue left on theGR® variant, passing successively by Pic and Col du Malrif.
(4) Leave theGR® on the right and take a good path up the ridge known as Eaux Pendantes. This single path leads easily to the summit of Grand Glaiza.
(5) To return, follow the same route you took on the way up to get back to the car park (S/E).
