How to fish it · for brown trout
When
Through the open trout season. Spring olives and sedges through May; summer evenings; small dark flies into autumn close.
Where
Pool tails and pocket water through the Côtes-d'Armor valley. Once one of Brittany's premier sea-trout rivers; the sea-trout fishery is now closed under the 2026 Brittany order, but brown-trout fishing remains.
Method
Upstream dry to risers; dry-dropper through the riffles. Breton spate freestone — fish 12 to 24 hours after rain on the drop. Long leader, fine tippet.
Kit
9 ft #4 — Breton spate freestone. Floating line, 12 ft leader to 4 lb fluoro. Studded boots.
Why this works
Fair conditions. Clarity is favourable (95), Prey activity is weakest (24).
