GR10 self-guided Section 6 : From Aulus les Bains to Merens

Self-guided GR10
Self-guided Walking
7 Days

6 Activity Days
From 565,00 €

The walk from Aulus-les-bains to Mérens in Haute Ariège connects the western and the central sections of the Pyrenees with the Ariège part of the mountain range. This region is known for its high plateau landscapes, deep valleys hemmed in by soaring summits, sometimes covered with a sprinkling of snow, and mountain lakes whose waters change in colour. In the evening, the Ariège gastronomy will get you back in shape for the next day.

From Aulus, the guarded refuge of Bassiès surrounded by lakes will satisfy your desires for wide open spaces. In Vicdessos region, then, the discovery of orris, ancient circular dry stone constructions will allow you to put meaning and images on what is called pastoralism in the Auzat valley. The arrival on Mérens, at the gates of the nearby Capcir and Andorra, after the mountain stage of the Rulhe refuge will finally convince you that you will have to return one day to Haute-Ariège.

A great loop walk from Aulus-les-Bains to a mountain lake and the superb waterfall, the Cascade d’Ars.

Day 2 : from Aulus to Bassies refuge

The GR 10 goes along the magnificent Bassiès ponds, and joins the lower part of the high Vicdessos valley in the direction of Auzat, at the foot of Montcalm, the last summit of more than 3000m altitude towards the Mediterranean. Then a superb  path leads to Goulier, passing through Olbier, a pretty little mountain village in the Ariege Pyrenees. Distance : 13km, duration : 5h, altitude gain : +450m, descent : -1000m.

Day 4 : from Goulier to Siguer

Starting from Goulier, the day's itinerary crosses many cols and passes through beautiful forests and mountain hamlets such as Lercoul and Siguer.

You will then cross the wide open spaces of the Pla du Four, ideal for grazing animals as the Courtal Marti and Balledreyte huts testify. You will then cross the Sirmont pass before descending to the Coudènes bridge.

Stay reviews

GR10 Self Guided from Aulus les Bains to Mérens les Vals

Everything during our week in the Ariege worked out perfectly! We knew we could not walk this section of the GR10 under our own steam because there is a notorious lack of accommodation and resupply points. Gaëtan's organisation was flawless. Our luggage transfers worked perfectly, the timing and distances given for the walks were spot on, and the accommodations were the best on offer along this challenging section of the walk. In fact one or two of the places we stayed (and ate!) were among our best experiences in France. Although we are experienced navigators we really enjoyed having the Respyrénées app to help us with navigation in some tricky spots - it was particularly helpful in finding our accommodations at the end of some long days. And what a nice surprise to meet Gaëtan himself when he came from Fois to pick us up for one of our transfers. Thank you so much for a holiday that was challenging in all the right ways, and none of the wrong ones!
