How to fish it · for Brown Trout
When
Through the Madrid trout season. Spring olives April through May; summer evenings; small dark flies into autumn close. La Pedriza altitude means the upper Manzanares fishes later than the lower river.
Where
Upper Manzanares through La Pedriza national park. Pool tails and pocket water through dramatic granite slabs. Small intimate Sierra de Guadarrama water.
Method
Upstream dry to risers; dry-dropper through the riffles. The water reads clear — long leader, fine tippet, careful approach.
Kit
8'6 ft #3 to 9 ft #4 — small mountain stream. Floating line, 9 to 12 ft leader to 4 lb fluoro. Studded boots.
Likely species
Stoneflies
Caddisflies
