Ranked for today
Grayling fly box

More balanced than the mountain-river pack. French nymphing still matters, but there is more room for dries, spiders and general searching flies.

About this water

Designated no-kill, fly-only, barbless stretch. Wild brown trout. Technical pocket-water fishing in clear flows. Spring through early autumn offers consistent opportunity. Modest gradient makes wading workable. Permits required; check Aude prefectural regulations.

Hatches & food

No emergence timing has been documented for the upper river, but OFB monitoring at Escouloubre and Axat confirms a diverse stonefly, caddis and mayfly fauna (including Perla, Isoperla, Rhyacophila, Sericostoma and Ephemerella) — direct evidence of a rich food base at these specific stations, not a calendar for the whole upper Aude.
