The Tech (Catalan: Tec) is a river in southern France, very close to the French-Spanish border. It runs through a valley in the Pyrénées-Orientales, in the former Roussillon, and is 84 kilometres (52 mi) long. Its source is the Parcigoule Valley, elevation 2,500 metres (8,200 ft), and it feeds the Mediterranean Sea. At Céret, the medieval Devil's bridge, once the largest bridge arch in the world, spans the river in an arc of 45 metres (148 ft) in length.
The Tech flows through the following towns: Prats-de-Mollo-la-Preste, Arles-sur-Tech, Amélie-les-Bains-Palalda, Céret and Le Boulou. It flows into the Mediterranean Sea between Saint-Cyprien and Argelès-sur-Mer, southeast of Perpignan.
