Lac d'Aubert is a high mountain lake at an elevation of 2.163m (7,096ft) above the sea level, located in Hautes-Pyrénées, a department in southwestern France. It is part of the Midi-Pyrénées region.
The road to reach the lake (known as Route des Lacs) is one of the highest paved roads in the French Pyrenées – higher than Col du Tourmalet. As the cliff road circles around towards the dam, the final stretch climbs some really fun hairpins.
The road includes maximum gradients of 15%. It is subject to winter snowfalls with such a high summit altitude, and the road can be closed anytime when the access is not cleared of snow.
