About this water

Mediterranean torrent flowing from central Corsican mountains to the west coast, steep, technical river where light bounces off white rock and the air carries salt. Tight, cascading pocket water requiring short-line nymphing and small dry flies. Endemic Corsican trout (macrostigma lineage) in cold, oxygenated flows. Clear water, conservative fish, ethics-heavy approach. No-kill conservation developing. Check Corse-du-Sud regulations.
