The River Thaw is a small Welsh river that flows through the Vale of Glamorgan, offering intimate reaches with a mix of fast runs and deeper pools typical of upland tributary systems. The fishery is best suited to anglers pursuing smaller specimens, with good opportunities for trout and grayling in the upper sections and coarse fish in the slower lower reaches. Access is generally permissive along much of the river, though local landowner relations should be respected and Environment Agency byelaws observed.
River Thaw observes the standard close season: 15 March – 15 June (rivers, England & Wales). Always check local byelaws before your visit. A rod licence alone does not grant access — most stretches require club membership or a day ticket in addition.
