Departure from the Lac d'Aubert car park. The road to get there is a toll road with an hourly rate and a maximum charge of £9 (06/2025). Park in the car park at the end of the road, about 100 metres from the lake shore. If necessary, the bivouac area is located just below the dam wall. It can only be reached on foot.
(S/E) From the car park, head towards the lake, go through a wooden barrier and continue left (south-south-east) on a track to the dam.
(1) Walk along the top of the dam. On the other side, follow a path marked with cairns south-south-west. You will soon reach a crossroads.
(2) Turn right towards Néouvielle (leaving the path leading to Pas du Gat on your left). The path remains clearly visible and well marked, but the climb becomes steep, through granite boulders, as you approach the north-eastern end of the Barris d'Aubert ridge that separates the two valleys.
(3) Cross the Brèche de Barris d'Aubert. The route heads west-northwest towards the Crête d'Espade. Aim for the Brèche de Chausenque, clearly visible in the middle of the landscape. Depending on snow conditions, crampons may be necessary to cross the persistent snowfields.
(4) Far below the breach, at an altitude of around 2,630 metres, the route turns west, then west-southwest.
(5) Pass the junction (not visible on the ground) where the ascent and descent tracks cross and continue south-west. This will take you to the Anciens Glaciers de Néouvielle (now, due to global warming, it would be more accurate to call them snowfields).
(6) Then head south, then south-east until you reach large boulders: you will often need to use your hands. Numerous cairns show the direction (and can be useful in addition to the GPS track in case of fog).
(7) Pass the junction (not visible on the ground) where the outward and return tracks cross again. You will arrive at the north-east ridge of the peak, about a hundred metres below the summit. Continue the final ascent with an easy climb up a narrow chimney. Reach the summit ridge, then the summit of Pic de Néouvielle.
(8) Take the same route back down, losing about 100 metres in altitude.
(7) There are two options here:
- Take the same route as on the way up, heading north-west towards the Anciens Glaciers de Néouvielle. Then head north-east to rejoin the main route at (5).
- For a more original and fun descent, continue almost due north. Reach a large, smooth, almost horizontal slab. Make your way down the large boulders, almost due north. Leave the large boulders and cross an area of rocks and very occasional persistent snowfields (the slope becomes gentler). Keep as far to the right as possible to avoid the large snowfield in the centre of the couloir you climbed up. This option requires confidence in downclimbing, grade F.
(5) Take roughly the same route as on the way up, in reverse, to reach the dam and then the lake car park (S/E).
