How to fish it · for Brown Trout
When
Through the Castilla y León trout season. Spring olives April through May; summer sedges in evening hours; small dark flies into autumn close.
Where
Pool tails and pocket water through the Segovian valley. The Cega runs from the Guadarrama — clear granite water, intimate scale.
Method
Upstream dry to risers; dry-dropper through the riffles. The water reads clear — long leader, fine tippet, careful approach.
Kit
9 ft #4 — Castilian default. Floating line, 12 ft leader to 4 lb fluoro. Studded boots — granite cobble runs slick.
Likely species
Stoneflies
Gammarids
