About this water

Corsica's longest river flowing from central mountains northward through lower-gradient terrain than most island streams. Endemic trout water with better volume than typical Mediterranean torrents. Mix of pocket water and longer pools. Nymphing and small dries effective. Regulatory development for no-kill sections ongoing.
