Park in the local authority car park on the right on the outskirts of the village, or – before 9.30 am in high season – in the village itself, in one of the private car parks. Both charge €5 per day (as of 2019).
(S/E) Finish walking through the village, heading towards the unmissable Cirque, which lies due south. Cross the Pont Brioule bridge near the gendarmerie and continue along the right bank for about 500 metres.
Reach the junction for the Refuge des Espuguettes, the Hourquette d’Alans and the Gloriettes dam. Yellow directional signs indicate all the destinations.
(1) Start the ascent on the left, first alongside the Ruisseau d’Alans, which flows down from the Petit Piméné and the Espuguettes, then into the Bois de Pailla. Although the path is not signposted, it is very clearly marked. On leaving the Bois de Pailla, just over an hour after setting off from Gavarnie, you can just make out the tip of the refuge’s roof.
(2) At the 1782-metre mark, on the vast Pailla Plateau, near a National Park sign, ignore the fork to the right towards the Cabane de Pailla (the ascent towards the Swan couloir between the two Astazou peaks), and head north-east up the final 250 metres, finding the best route to the refuge via the main path – which is clearly marked and visible – or the countless secondary paths and cattle tracks.
(3) From the refuge, on the grassy summer pasture plateau, take care to stay on the main path. Head north-east towards the Col du Pimené, below the Petit Pimené. Pass the watering hole and the Espuguettes marsh on your right and continue up the slope, which becomes steeper once again.
Circumvent the Plateau des Cardous to the north, adjusting your course towards the east-south-east and then towards the south-east via several hairpin bends; pass the 2,232-metre hillock, keeping it on your right, then take one final hairpin bend. At 2,260 metres, you’ll reach a fork in the path with a signpost.
(4) Turn left here, heading north-north-west along the south-western flank of the Pimené. After several hairpin bends, reach the Col du Pimené (2,482m). From here, you cannot see the Pimené itself, only its ‘little brother’ to the left, almost due north.
(5) At the pass, head left to stay on the ridge and climb to the summit of the Petit Pimené (splendid view).
(6) Descend due north to the small pass (2,647 m).
(7) Resume the ascent of the ridge heading north. The slope becomes really steep.
Follow the Pyrenees National Park markings (the letters ‘PN’ and chamois in red on a white square background).
Caution: after a very gruelling 150m climb where you’ll need to use your hands and navigate a few exposed sections, you’ll reach the Pimené. On the final metres of the ascent, make sure you stay right on the ridge line – that’s where it’s safest!
(8) The descent follows the same route back to the small pass.
(7) Then take a path skirting the Petit Pimené to the east (marked in purple on the IGN map).
(5) This will take you back to the Col du Pimené. Continue south-east along the ridge leading to the Hourquette d’Alans. This path is fairly well marked, but these ridges remain challenging nonetheless. Pass the unnamed peaks at 2,487m, 2,465m and 2,521m. There is no longer any marked path for the final 300 metres. On the 2,521m peak, a cairn is visible from a distance.
(9) The final rocky spur or outcrop is very difficult to access (erroneously marked as 2,505 m, but is in fact higher than the one crossed at 2,521 m). You must bypass it on the left (east) as soon as the rock face rises steeply opposite the ridge line. Then descend towards the Cirque d’Estaubé and rejoin the path coming from the Barrage des Gloriettes, which can be seen from the ridge.
(10) Turn right and climb up to the Hourquette d’Alans. This pass alone is well worth the trip!
(11) Turn right and descend directly below the rocky outcrop you bypassed earlier and the ridge.
(4) At the junction you passed on the way up, turn left and descend to the Refuge des Espuguettes.
(3) Continue down the same route as on the way there until you reach Gavarnie (S/E).
