Haute-Garonne is a département in the southwest of France named after the Garonne river.
Haute-Garonne is part of the current région of Midi-Pyrénées and is surrounded by the départements of Hautes-Pyrénées, Gers, Tarn-et-Garonne, Tarn, Aude, and Ariège. It also borders Spain in the south (province of Lleida and province of Huesca).
The department is crossed by the Garonne River for nearly 200 kilometers (125 miles). The extreme south of the département lies in the Pyrenees mountain range and is very mountainous. The highest elevation is the Peak of Perdiguère, at 3,222 meters (10,571 ft) above sea level.
