Lac de Bastan supérieur, Mountain lake in Vielle-Aure, Hautes-Pyrénées, France.
Lac de Bastan supérieur sits at an elevation of 7,415 feet (2,260 meters) and features clear waters surrounded by granite formations, alpine meadows, and hooked pine trees that create a varied natural setting.
The area surrounding this glacial lake has served for centuries as grazing land for local pastoral communities, who used the water to tend their livestock during summer transhumance in the high Pyrenean valleys.
Located within the Néouvielle massif, this lake is part of a Pyrenean heritage celebrated through regional mountain traditions, hiking culture, and outdoor recreation that connects visitors to the natural environment of southwestern France.
Visitors can reach the lake by following the GR 10 trail from Lac de l'Oule or by starting from Artigusse parking area at 5,226 feet (1,593 meters) near Aragnouet, with the hike taking approximately two hours.
This lake forms part of a series of three connected glacial basins known as the Bastan lakes, where the reflection of Pic de Bastan on the water surface offers photographers and hikers memorable views throughout the day.
