The River Wye (/waɪ/; Welsh: Afon Gwy [ɡʊɨ̯]) is the fourth-longest river in the UK, stretching some 250 kilometres (155 miles) from its source on Plynlimon in Mid Wales to the Severn Estuary. The lower reaches of the river form part of the border between England and Wales. The Wye Valley (lower part) is designated a National Landscape (formerly an Area of Outstanding Natural Beauty). The Wye is important for nature conservation and recreation, but is affected by pollution.
