Park at Port de Balès.
(S/E) From the car park, head towards the “Port de Balès” sign on the Haut-Garonne side, and at the signposts, take the path heading north-west. The route leads to a track which you should take on the left. After five hairpin bends, leave the track at the end of the sixth.
(1) To the west, take the path that climbs to Mont Né (signposted). Be careful, as the markings are rather irregular on this section. After some steep climbs, the slope gradually levels out and you come to a slight junction (unmarked).
(2) Head right to reach the ridge leading to Mont Né, heading south-west.
(3) Fantastic views from the summit: notably the Pic du Midi and Aneto. Descend the fairly steep slope carefully towards the Port de Pierrefite.
(4) Head south-west towards Lac de Bordères, following theGRP® "Oueil-Larboust". A few hundred metres after entering the Montious Nature Reserve, you’ll reach Lac de Bordères.
(5) Return to Port de Pierrefite.
(4) Take the track on the right along theGRP® "Oueil-Larboust".
(6) Pass the Mont Né Refuge and continue along the track to reach the D51d.
(7) Follow the road to the left to reach Port de Balès and, consequently, finish this wonderful hike (S/E).
