The River Clun runs mostly through Shropshire, England and joins the River Teme at Leintwardine, Herefordshire. The Clun Valley is part of the Shropshire Hills AONB.

The River Teme rises in Mid Wales, south of Newtown, and flows southeast roughly forming the border between England and Wales for several miles through Knighton before entering England in the vicinity of Bucknell and continuing east to Ludlow in Shropshire. From there, it flows to the north of Tenbury Wells on the Shropshire/Worcestershire border on its way to join the River Severn south of Worcester. The whole of the River Teme was designated as an SSSI by English Nature in 1996.
