The River Nadder is one of the chalk stream rivers of southern England, much sought after by fly fishermen because of its clear waters and abundance of brown trout. It is one of the main tributaries of the Salisbury Avon, rising from a number of springs and small streams at Donhead St Mary in south Wiltshire.
The river winds its way east-northeast, heading towards the medieval cathedral city of Salisbury. It flows through Tisbury, Upper Chicksgrove, Lower Chicksgrove, Barford St Martin, and Burcombe before reaching Wilton, where it passes through the grounds of Wilton House and is joined by the River Wylye. After passing Quidhampton and Harnham, where it forms watermeadows, the Nadder joins the Avon near Salisbury Cathedral.
