About this water

A central Gipuzkoa trout river of excellent character, flowing through relatively unspoilt catchment toward the coast. At 59 km, it provides diverse habitat with particular strength in middle and upper sections holding abundant wild browns. Mixed geology ensures good water quality and varied substrate. Spate nature (4-hour response) provides reliable fishing windows for winter browns and spring/summer sea trout. Less developed than salmon-focused neighbours, offering quieter angling with consistent quality. Predominantly wild and undisturbed habitat with good riparian cover. Spring (March–May) excellent for browns; sea trout extend season May onwards. Ideal for those seeking wild river experience without permit complexity.

Hatches & food

In the steep, often pressured Atlantic rivers of the Basque Country, trout opportunities centre on spring olives and other up-wings when flows and colour briefly line up, with caddis and buzzers helping to sustain sport into early and mid-summer, and terrestrials from grassy, wooded margins adding surface food in quieter, recovering reaches.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
A drop and clear would lift the flow and clarity scores.
The dawn and dusk windows score higher than the midday lull.
