The Afon Trannon is a small Welsh tributary of the River Severn, flowing through rural Powys with a mixture of fast-flowing sections over gravel and slower, deeper pools ideal for trout. The river holds wild brown trout and grayling populations, offering intimate fly-fishing opportunities in a relatively undisturbed setting with good bank access in many stretches. Most fishing requires permits from local riparian owners or the Powys Angling Association, so permission should be sought in advance of visits.
Anglers should note the close season on Afon Trannon: 15 March – 15 June (rivers, England & Wales). Club membership or day ticket access is required in addition to your EA rod licence on most stretches.
