How to fish it · for sea trout
When
From dusk into the first half of the night.
Where
Deeper pools and slower glides · hold water and current seams.
Method
Fish dark patterns on a sink-tip or lightly sunk line, especially near structure.
Kit
10 ft #6/7 rod, floating line with a sink-tip option, 8–10 lb fluoro tippet for the swing.
Why this works
Good conditions. Temperature is favourable (100), Prey activity is weakest (38). ⏰ Sea trout become most active from an hour before dusk. This stretch closes at 22:15 — your legal window captures the start of the best fishing. Fish the last 90 minutes hard. Overcast evenings extend the effective window.

About this water

The Bedón is a diminutive limestone stream — just 12 km of crystal-clear mountain water holding small but eager wild browns (10–20 cm). Ultra-responsive (2 hours to spate), with pools and runs where a 3-weight feels powerful. Mayfly hatches May–June are exceptional; terrestrials work in summer. Accessible from coastal Llanes, uncrowded. A river that teaches streamcraft and observation in a package you can fish in an afternoon.

Under the surface

The Bedión is a slate-fed tributary arriving into the Dobra network. The river is smaller, steep, and spate-responsive throughout its course. The upper reaches show pure slate character in step-pool confines; the descent is rapid and the water amber-toned throughout. The Bedión's technical simplicity is its defining feature — step-pool or briefly interrupted riffle, responding immediately to Cantabrian rainfall. The pools available are secondary to the river's main character, which is responsive descent. The wading demands care throughout; the insecure slate slabs and the rapid current require commitment.
