How to fish it · for brown trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
⛔ Water at 22°C. This is the line where catch-and-release kills brown trout. Do not fish for them today.

About this water

A compact Sierra Nevada headwater near Lanjarón, best treated within the same metamorphic mountain template as Trevélez and Poqueira. Cold snow-fed water, steep gradient, and short plunge-pool structure create a compressed practical season and a much tighter tactical style than on the Cazorla limestone cotos.
