The River Severn, at 220 miles (354 km) long, is the longest river in Great Britain. It is also the river with the most voluminous flow of water by far in all of England and Wales, with an average flow rate of 107 m3/s (3,800 cu ft/s) at Apperley, Gloucestershire. It rises in the Cambrian Mountains in mid Wales, at an altitude of 2,001 feet (610 m), on the Plynlimon massif, which lies close to the Ceredigion/Powys border near Llanidloes. The river then flows through Shropshire, Worcestershire and Gloucestershire. The county towns of Shrewsbury, Gloucester and Worcester lie on its course.

The combined river flows past the hamlets of New Mills, Manafon and Pant-y-ffridd, accompanied by the B4390 road all the way to Berriew. Other tributaries include the Nant Wtre-wen, Crygnant, Nant y Llyn Mawr and Dolgar Brook.

The Vale of Montgomery is an area of low land straddling the border between Shropshire, England and the former county of Montgomeryshire, Wales. The three principal settlements within it are the former county town of Montgomery and the village of Churchstoke, both in Wales, and Chirbury in England. The earthworks of Offa's Dyke run NNW-ESE through the middle of the vale and are followed by the Offa's Dyke Path. The national boundary also follows this monument for 3 km within the vale. The River Camlad rises to the southeast of the vale whilst its tributary the Caebitra rises to its southwest. They combine at Churchstoke and flow north within a gorge along the eastern margin of the vale, before turning west across the north end of the vale to join the River Severn.
