How to fish it · for Atlantic Salmon
When
Summer through autumn. Fish on the drop after rain — the Neath is not a spring salmon river.
Where
Middle and lower Neath pools above the tidal limit. Neath & Dulais AA named beats.
Method
Small doubles 10 to 12 across-and-down on a floating line; small tubes on a sink-tip in spring water. Cover the pools methodically. Mandatory catch-and-release under NRW byelaw — every salmon goes back.
Kit
12 ft #7/8 double-hander or 11 ft switch. Floating line plus light sink-tip. 10 to 12 lb fluoro tippet.
Why this works
Good — water temperature is working for you, but time of day is the limiting factor today.
Likely species
Stoneflies
Gammarids

About this water

Out of the Brecon Beacons through Glynneath and down past the town of Neath to Baglan Bay — accessible South Wales sewin and salmon water with one of the steadier club traditions in the region. Fishing Wales names the Neath specifically as a starting point for a first Welsh sea trout, and the Neath & Dulais Association ticket gives genuine access. The lower catchment is industrial in character; the proper fishing is in the middle and upper river. Atlantic salmon are under serious conservation pressure — Natural Resources Wales mandates catch-and-release for salmon on all rivers, so all fish must be returned.
