About this water

The upper Aude at Axat tumbles through limestone gorge where fishing is secondary to the sheer drama of the place. 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.
