About this water

Small, fast South Brittany river flowing from Scaër to Pont-Aven. Intimate water — 100% wild brown trout on Armorican granite. Fly-fishing on designated beats. Responsive to Atlantic rainfall for volume. Spring through early summer best for dry-fly work. This is not showpiece water, but it rewards careful fishing and respect for wild trout. Check AAPPMA for access.
