Top Ten Trout Streams in the United Kingdom

This famous river, complete with its spectacularly beautiful (though in places dangerous) tributary the Cothi and the Cothi's smaller cousin, the Gwili, provides world-class flyfishing from the beginning of the season to the end. The Towy holds both resident browns and beefy salmon, but is most famous for its sea-run browns, which every year run to 15-plus pounds. These great fish get into the lower main system as early as April. By midsummer, numbers are boosted by heavy runs of fish to three and four pounds. A fresh run of smaller fish and a sprinkling of fresh-run big fish liven things up in September. Useful base: Carmarthen.
