About this water

A western Cantabrian coastal river in the Gandarilla zone, flowing through Roiz and the Valle de Valdáliga to the sea near Comillas. The Escudo is a small spate river with mixed-geology freestone bedrock — pool-riffle structure, partial canopy, classic small-Atlantic character. Wild brown trout only. Best fished in May and June; the river drops away in summer.

Hatches & food

In Cantabria's shorter mountain and foothill trout rivers, fish make the most of spring olives and stoneflies in clear windows between freshets, then switch to evening caddis and small buzzers through the warmer months, with terrestrials becoming a key option in sheltered glides and under tree cover once summer settles in.
