Park at Pont de la Neige, almost at the top of the Col de l'Iseran on the Haute Maurienne side (2,530 m).
(S) Head south-west along the path towards the Col des Fours, indicated by a yellow sign (marked 1h50).
The path crosses the ravine and climbs quite steeply. The trail is clearly visible, with numerous cairns, but the markings are not very clear as the paint has been worn away by the weather. There are no forks in the path, just follow the cairns.
Depending on the snow conditions, the trail avoids the snowfields, so there are many parallel tracks that all lead to the pass.
(1) The first steep section ends here. A flat area with a large rock marks this point. Continue south, following the cairns.
(2) Once again, the trail climbs steeply up the rocks. At the end of the season, the passage is over scree.
(3) At the Col du Grand Fond, turn right towards the Col des Fours
(4) At the Col des Fours sign, turn left and leave the path that descends towards the Refuge des Fours. The trail is less clear from this point onwards.
(5) Take care: there is a small difficult section that is only suitable for experienced hikers. You can stop at the Col des Fours and avoid taking any risks.
(6) The highest point of the walk is 3,074 metres according to the IGN. Return via the same route.
