Departure from Grand Carroz, a hamlet in Entremont-le-Vieux at the end of a road leading north from the CD 912 (Route du Col du Granier), 600m upstream from the main town (Épernay).
Park at the wash house on the left less than 100m before the hamlet.
(S/E) Walk up the last few metres of the road to the centre of the hamlet and turn right onto theGR® marked trail which descends to Cozon.
Climb back up opposite, still on the marked path, pass Loutraz and reach a crossroads at a right-hand bend after a ruin (1190m).
(1) Leave the marked path and head north on a trail that descends slightly to cross a stream, then gradually climbs through the forest before crossing to the left of steeper slopes leading to the Col de la Drière, where it joins the trail descending from Pointe de la Gorgeat.
(2) Take the ridge path on the left, which passes the geographical pass of La Drière (or Midi) and climbs the ridge leading to Mont Pellaz (or Pellat or Lentille).
(3) Continue along the ridge path which descends to the Col des Fontanettes (or Passage de la Cochette).
(4) From the pass, ignore the marked trails to the right and left and continue straight ahead on a faint but easy-to-follow path that climbs steadily up the Montfred ridge. When the ridge you are climbing flattens out into forest, turn right to join a parallel ridge that leads to the highest point of Montfred.
(5) Continue along the ridge, which is sometimes cleared by the path that continues, passing the 1401m point (slight climb). When the descent becomes steeper, veer left to maintain moderate slopes in the forest and descend until you cross a wide forest road coming from Les Marots.
(6) Take this track to the left: it heads north, remaining more or less level. After two hairpin bends, it reaches the top of a meadow at the foot of La Lance.
(7) From this sort of small pass, follow the track north for 50 metres, then leave it on the left onto a path that descends into a thalweg and joins a forest track coming from the right. Take this track to the left to descend gently towards the meadows, which you follow on the right.
At the entrance to the forest, the path slopes again to intersect the marked path coming from the Col des Fontanettes.
(8) Take the marked path opposite, which leads to Grand Carroz and from there to the car park. (S/E).
