It continues, leaving on the left a sourceIt crosses a kind of small square and heads towards the steps in front of us, next to the Italian restaurant: "La Fontana del Balneario". Approximately 10 minutes further on, we will see a crossroads on the left that leads to Bachimaña. We continue to the right, along a path that zigzags through the pine forest. At an altitude of 2,140 metres - one hour and twenty minutes - we will see a small refuge on the right, 150 metres away. We continue climbing for 10 minutes and reach a rest area, crossed by the pipe coming from the Brazato reservoir. Cross it and continue ascending (30 minutes) along the slope on the left.

📌 (2h00min; 4,8 kms) Dam of the Brazato reservoir (2.380m). From here you can see a path that ascends the northern slope of the reservoir, a stretch that can be tricky if it is snowy. The Brazato reservoir is lower and lower. At the end of the ascent we see the Ibones Altos del Brazato on the left. To the right we see the Brazato pass, to which we now head halfway up the slope.

To the west, the deep valley where the Panticosa Spa is located; on the other side, the valley of the Ara River and the Vignemale. To the north, the path leaves the rocky peaks of the Batanes and descends on uneven terrain, between boulders, through the ravine of the same name, bordering the Ibones de los Batáns on the left.

📌 (4h15min; 9,8 kms) River Ara (2.031m). At the confluence of the ravine with the waters of the Ara River there was an unmarked variant of the GR11 that came directly from the Bachimaña reservoir. From this point there is still a long descent following the waters of the Ara River. The path descends between meadows along the left bank of the river, at the foot of the Vignemale massif. The Cerbillona Peak (3,247m) dominates the valley and further down, it is the Tapou (3,151m) that stands out. After 10 minutes we pass a rain gauge. Several 💧 streams flow down the left slope.water free from contamination by livestock. Further on, we will see a footbridge on the right (35 minutes after crossing the Ara) and twenty minutes later we arrive at the...
