Monument to Spanish Tour de France Winners and View of the Val d'Aran

Highlight • Monument

Each bend preceding the stele from Bossost honors one of the Spanish winners of the great loop up to the stele which recapitulates these victories. The point of view is worth making a small contemplative stop.
