Lac d'Embarrat inférieur

Lac d'Embarrat inférieur is a small glacial lake straddling the boundary between the Estaing and Cauterets valleys, deep inside the Pyrenees National Park in the Hautes-Pyrénées department. Administratively shared between the communes of Estaing and Cauterets, it is best known to hikers as one of the stops on the way into a high mountain cirque where rock, water, and summer pastures come together in a landscape typical of the French Pyrenees.

Where exactly is the lake?

The lake sits at roughly 2,078 metres above sea level, in a small glacial cirque suspended between the Estaing valley and the Marcadau valley on the Cauterets side. It is enclosed by the Cardinquère peak (2,509 m) and the Aiguilles de Castet Abarca (2,568 m), which wall it in on almost every side and give the spot its closed-in, sheltered feel — a feature that is actually baked into its name.

How big is the lake?

Don't expect a vast body of water: Lac d'Embarrat inférieur covers around 1.8 hectares and reaches a maximum depth of about 4 metres. Like most Pyrenean mountain lakes, it is fed by snowmelt and runoff from the surrounding ridges, and its water level varies noticeably with the season.

Where does the name "Embarrat" come from?

The name comes from Occitan, the Gascon dialect spoken across this part of the Pyrenees, and refers directly to the terrain — the lake occupies a basin almost entirely ringed by rock walls, effectively "shut in" among the peaks. The qualifier "inférieur" (lower) distinguishes it from the higher-lying Lac d'Embarrat supérieur, its twin further up the same cirque.

How do you get there?

The usual starting point is Pont d'Espagne, which has paid parking. From there the trail follows the Marcadau stream before branching off at the Pont de Cayan bridge to climb through forest toward the cirque holding the lake. The full ascent typically takes around two and a half hours one way. There is no technical difficulty involved, but the climb is steady and sustained once past Pont de Cayan, so proper hiking boots and enough water are worth bringing along.

What else is nearby?

Most hikers treat Lac d'Embarrat inférieur as a waypoint rather than a final destination: trails continue on to the higher Lac d'Embarrat supérieur, as well as to Lac du Pourtet and Lac Nère. In summer, the surrounding Marcadau pastures are grazed by Lourdaise sheep, and the sound of their bells often echoes off the cirque's rock walls, adding a distinctly pastoral note to the setting.
