Madriu-Perafita-Claror Valley.

The Madriu-Perafita-Claror Valley, a UNESCO World Heritage Site since 2004, showcases the deep cultural and historical ties between humans and the high Pyrenees over thousands of years. Spanning 4,247 hectares, this rugged national park features dramatic glacial landscapes, including steep cliffs, expansive pastures, and lush wooded valleys, representing 9% of Andorra's territory. It preserves a communal land-ownership system from the 13th century, alongside remnants of ancient settlements, terraced fields, and iron smelting sites. The extensive hiking network, including the GR7 and Coronallacs Trail, invites explorers to experience its natural beauty and rich biodiversity, making it a prime destination for nature lovers and outdoor adventurers alike.
