The Valira River is a significant waterway located in the eastern Pyrenees, primarily flowing through Andorra and into Spain. It is approximately 25 kilometers long and is known for its clear waters and picturesque surroundings, making it a popular spot for outdoor activities like hiking and fishing. The river is formed by the confluence of two main tributaries, the Valira del Nord and the Valira del Sud. It eventually merges with the Garonne River, contributing to the larger river system in the region. The Valira River plays an essential role in the local ecosystem and supports various wildlife.
