About this water

Tributary of the Ellé at Quimperlé described as a wild-trout paradise where Armorican granite creates clear, responsive water. Small stream requiring intimate casting and careful wading. Fly-fishing potential. Not crowded water — solitude and wild trout are part of the appeal. Spring through early autumn. Check AAPPMA for access and regulations.
