REFUGE DU MAUPAS

A warm and friendly little eagle's nest, the 30-seater Maupas refuge (3 bat-flancs for 10 people on 3 levels, no shower room or bathroom, a cold water point and an outside WC), invites you to disconnect from the hustle and bustle of summer by taking a step up into the heart of the Pyrenees! Away from the fine sand, but very close to peaks over 3000m and the Crabioules cirque; passing through forests of hundred-year-old beech trees, mountain pastures, streams and waterfalls! A beautiful succession of lakes teeming with fish, itineraries where you can often spot isards and vultures, beautiful rock faces to climb - all the elements are there to make your visit to Le Maupas a success.The Maupas refuge is a remarkable lookout point overlooking the Crabioules cirque and Superbagnères. Close to lakes, it is an essential stop-off point on the way to the Pic du Maupas or the Pic de Boum. It is ideally situated for a stopover on a loop between the Gouffre d'Enfer, the Cirque des Crabioules and the Lacs Bleu, Charles and Célinda. Start from the car park at the bottom of the Lys valley, above Luchon. Ascent from the Vallée du Lys: 4h - 4h30, 1300m ascent through forests, meadows and lakes. Meals, drinks and dormitory accommodation provided. Bivouacs available nearby. The Maupas refuge has a single dormitory for 30 people, 3 bat-flancs for 10 people on 3 levels. There is no shower room or bathroom, but there is a cold water point and an outside WC. A dining room seating 26. When the refuge is not guarded, there is no catering, no kitchen and no crockery available. Free access to the dining room and dormitory. Payment can be made in cash or by cheque on site (box available) or via the refuge's website. No reservations possible, no drinking water, but heating and electricity.

Additional information

Detailed stages

- From the Vallée du Lis car park, cross the stream on your left and follow the small tarmac road for a few metres.
- A little further on, signpost no. 32 indicates that you should take the path climbing up on your left. You will quickly enter the forest. The path climbs steadily in hairpin bends.
- Just below, you will be able to look down on the Lac Vert, the Lis valley and the Superbagnères resort.
- A little further on, you will leave the forest and arrive at the Artigue meadow (1,395 m). Take the path climbing up to your left. You will re-enter the forest and follow the Houradade stream. Admire the various waterfalls along the way.
- At the next intersection (1,680 m), turn right towards the Maupas refuge (sign). Cross two footbridges and the path climbs steeply through hazel trees. A small pass (1,755 m) leads to a small plateau. The path continues to climb straight ahead. It winds upwards and you will see the penstock on your right.
- Pass the ""pumping station"" (2,232 m) and a few minutes later, at the intersection, turn left. With a little more effort, you will pass the rocky ridge equipped with a handrail (2,354 m) and come to the short descent leading to Lac Bleu (2,265 m).
- Return via the same route.
