From Barèges, via the RD 918, before Tournaboup, take a forest track on the right leading up to the “Chez Louisette” inn and park in one of the many small car parks on the edge of the forest.
(S/E) From the car park, head to the base of the Piquette chairlift.
(1) Head due south along a grassy path to Camp Rollot.
(2) Continue straight on, heading due south, along a track suitable for vehicles alongside the Ruisseau de la Glère until you reach a fork in the track (alt. 1,685 m).
(3) Head due south up the paths criss-crossing the bends in the track leading to the Refuge de la Glère. You’ll reach a fork.
(4) Turn right and walk for 150 m until you reach the end of the wide track (alt. 2,070 m).
(5) At the junction, take the path heading south-east, continue along the hairpin bends and reach the Refuge de la Glère (signposted).
(6) Continue southwards, overlooking Lac de la Glère and Lac de Coume Escure.
(7) At the crossroads, turn left towards the east, heading for Lac Det Mail.
(8) At the lake, turn right towards the south to reach its neighbours: Lac de la Manche, and the Lower and Upper Estelat Lakes. After these lakes, the path is not very well marked in places, so keep a close eye out for the cairns. Continue due south, following a small stream to its source.
(9) Upper Lake Estelat. Continue southwards towards the Col de Coume Estrète. The ascent is over scree, so watch out for loose stones, but it’s not dangerous. You’ll reach the Col de Coume Estrète.
(10) Turn left onto the easy ridge path until you reach the junction for the return route (alt. 2,890 m).
(11) Continue the ascent along the ridge to the summit of the Turon de Néouvielle (elevation 3,035).
(12) From the summit, you can admire the lakes of Cap de Long, Bugarret and Couyela Det Mey, as well as all the surrounding peaks. Turn back along the ridge path to the previous junction.
(11) Turn right onto a path heading due north, descending to the Maniportet Lakes (Lac Glacé and Lac Bleu), remnants of an ancient glacier.
(13) Just after Lac Bleu, turn right, heading due east, along its southern shore, then follow the northern shore of the elongated Lac Vert along its left bank up to the 2626 m mark.
(14) Just after Lac Vert Allongé, turn right, heading due north, at the three-way junction to reach several small lakes and the southern shore of Lac det Mail.
It is possible to turn left; the two paths join at Lac de Mail.
(15) Turn right, heading due north, towards Lac de la Mourèle, then Lac de Mounicot.
(16) At the fork (alt. 2,110 m), turn right, heading due east, for a short detour to Lac d’Astazou.
(17) Turn back.
(16) Continue straight on, heading due west.
(18) At Lac de la Glère, turn right and cross the stream of the same name.
(19) At the southern tip of Lac de la Glère, carry on straight ahead due north, following the Ruisseau de la Glère. You’ll reach a fork in the path that you passed on the way there.
(4) Carry on to the left for 150 m until you reach the wide track suitable for vehicles.
(5) Follow this track downhill to the car park (S/E).
