Headwater country — the Ser is the kind of river you find when you've been following a track that stopped looking like a road some time ago. Wild browns that have seen nothing but natural flies and the occasional heron. The fishing is not complicated. Getting there takes some doing.
The Ser is a smaller slate-fed river in the eastern Asturian system, spate-responsive and amber-toned. The upper reaches are step-pool through Cantabrian slate; the descent is steep and response to rainfall immediate. The Ser maintains its mountain character throughout — responsive, slate-stained, belonging fully to the Cantabrian system. The pools available are brief; the character is descent and response.
Wading: Slick wet slate slabs at step lips
In the mountain-to-sea trout rivers of Asturias, olives and other mayflies do much of the work in spring whenever levels and colour allow, followed by strong evening caddis and steady buzzer life through early and mid-summer, with terrestrials and mixed surface food from wooded, pastoral banks rounding out the diet whenever flows drop back into safe wading range.
