Clwb Godre'r Mynydd Du
The only club that owns water on the Amman itself (the rest is public/free fishing) — a beat from Pontaman to Garnant, one of seven beats the club holds across the Amman, Cothi and Towy. A good run of sizeable sea trout from midsummer, plus a late-season salmon run. Fish here are heavily reliant on the sea-trout life history — a 2013 Wild Trout Trust survey found the river's food supply too thin to support a large standalone resident brown trout population.
Membership: adult £30, concessionary £20, River Aman-only £15, under-16 £5 (2026 pricing). Day tickets bookable via Fishing Passport.

Ammanford & District Angling Association
Around 8 miles of combined Amman/Loughor fishing (not separately broken out), from Llandybie down to Hendrewen near Pontardulais. Salmon and sea trout catch-and-release all season under club rules stricter than NRW's statutory minimum (sewin returned before 1 May and after 31 Aug too).
Salmon/sewin season 20 Mar-17 Oct (C&R all season); brown trout/eels 3 Mar-30 Sept. Barbless/de-barbed hooks required club-wide. Confirm current day-ticket availability directly.

About this water

A Black Mountain (Mynydd Du) spate stream running south through Brynamman and Glanamman to join the Loughor at Pantyffynnon. A genuine sea trout river — the brown trout population itself leans heavily on the sea-trout life history rather than standing alone — with a late-season salmon run that's stronger in the lower river than the upper. Anthracite mining, tinplate and chemical works have left a legacy of elevated copper and zinc, and current storm-overflow data shows frequent, sustained sewage discharges around Brynamman, Glanamman and Ammanford — an honest caveat alongside the genuine fishing. No grayling: absent from the Grayling Society's own regional guide, consistent with the river's non-limestone, upland-spate character.
