Looking over the Teme Valley from Bailey Hill, a minor road which runs from Knighton to Llangunllo, and one of Wales' most scenic routes. In the foot of the valley is Knucklas Viaduct on the Heart of Wales railway line. The River Teme marks the border with England, and beyond it the rolling hills of South Shropshire reflect the gradual change of the landscape from the rugged Radnorshire uplands to a more greener, more sheltered land.
