Another beautiful picture that the Arán Valley gives us. This time from the Vielha pond, with views of Aneto and the surrounding mountains of the Pyrenees. We will arrive by a dirt road. Located at 1638 meters of altitude.

From this lake you can appreciate the views of the top of Pica Palomera, at 2460 meters high. Due to mining activity, both the pond and the surroundings were affected. Today, the water has a much more acidic pH than most of the lakes in the Pyrenees, which does not allow the survival of aquatic vegetation or vertebrate animals.

From Vielha, take the N-230 road towards Les and Francia. At approximately five kilometers and at the height of the village of Pont d'Arros, we will turn right to follow a paved forest track for twelve kilometers. The road is in perfect condition but it has significant percentages of unevenness and in some sections it is very narrow and it is advisable to be careful. Every kilometer a sign informs us of the percentage of slope of that section and the height gained.
