UNESCO World Heritage siteStunning natural wonder
Covering roughly 9% of Andorra's total area, this breathtaking glacial valley is a masterclass in the delicate balance between human pastoralism and harsh mountain environments. Historically significant for its 700-year legacy of sustainable land use, visitors and environmental students flock here to observe terraced fields, ancient shepherds' cabins, and pristine alpine flora. The best season to visit is from late spring to early autumn for optimal hiking conditions.
