Access via Bonneval-sur-Arc at the far end of the Maurienne valley. Take the Col de l'Iseran road and park at the Pont de la Neige car park.
(S/E) Head south towards the Col des Fours, taking theGR®5variant marked in red and white. The first 200 metres of ascent are quite steep; the path climbs rapidly before the gradient eases off. You’ll reach a crossroads of paths. Leave a track on your left heading towards the Cols de Bézin and des Roches and head right across the terrain to reach the first pass.
(1) Turn left to reach thefirst summit. Enjoy the lovely view here of the Ancien Glacier de la Jave and Fond lakes.
(2) Return to the previous pass.
(1) Continue left to reach the Col des Fours quickly via a short traverse.
(3) Head left for the short climb up to the Pointe des Fours, where you’ll need to use your hands on the rock once.
(4) Return to the Col des Fours.
(3) Start the ascent of Pélaou Blanc directly opposite, avoiding a rocky outcrop to the left. Throughout the traverse, keep to the ridge line or to the left on the Tarentaise side. The path is clearly visible and follows the ridge line. This will take you to the summit of Pélaou Blanc. Enjoy the breathtaking view that you’ll never tire of.
(5) Begin a short descent to reach the Col de l'Arselle. Continue with a further ascent, slightly more challenging than the previous one as the ground—part soil, part gravel—becomes significantly more slippery, to reach the Pointe de l'Arselle.
(6) Continue with another descent, tricky at first, towards the Col de la Calabourdane. This descent takes you down a steep slope amidst large boulders, then over an easier ridge.
At the pass, there are two options:
- take a shortcut and join theGR®5below on the right,
- continue along the route shown on the map and climb back up towards the Ouillette.
Please note that this ascent is the most perilous due to the nature of the terrain, the steep slope and the trail fading away, but the climb is not long and the route is fairly obvious.
You will then reach the summit of the Ouillette.
(7) Then begin the descent from the Ouillette; it is very slippery on the steep section but becomes easier on the snowfield. Climb up to reach the summit of the Pointe des Lessières via a beautiful, narrow ridge of solid rock. Enjoy a final panoramic view from here.
(8) Now descend by following thefirst summit cairns you come across on the ridge.
Please note that this descent towards the Col de l’Iseran is steep, very slippery and dangerous as it is used by many climbers who erode the path. It then becomes easy over the final few metres of descent. Head towards Notre-Dame de l’Iseran.
(9) Continue towards the road and take theGR®5on the right to return to the Pont de la Neige car park (S/E).
