Cirque de Troumouse, Glacial cirque in Gavarnie-Gèdre, France.
Cirque de Troumouse is a glacial cirque in the Pyrenees, in the commune of Gavarnie-Gèdre, with steep rocky walls that wrap around a wide open basin. The floor of the cirque is flat and grassy, with the surrounding ridges rising sharply on three sides.
The cirque was shaped over millions of years as glaciers slowly carved into the rock of the Pyrenean ridge, scooping out the bowl-like form that remains today. When the ice retreated, it left behind a flat valley floor that generations of shepherds have used as summer pasture.
The name Troumouse likely comes from an old Occitan word meaning a hollow or hole, which fits the shape of the basin well. In summer, shepherds still bring their animals up here along traditional routes, and the sound of bells and moving herds fills the valley.
The cirque is reachable by car in summer along a toll road that leads up to a parking area near the top of the plateau, from where walking paths fan out across the basin. The road is usually closed in winter, so a visit is only possible during the warmer months.
The basin of Cirque de Troumouse is one of the widest of its kind in the Pyrenees, giving it an almost flat interior that feels more like a high plateau than a mountain valley. This unusual width means you can walk deep into the cirque without the enclosed feeling typical of narrower glacier-carved basins.
