The Wensum Valley is a ribbon of countryside that extends right along the River Wensum into the heart of Norwich. The varied landscape of the Wensum Valley is a haven for wildlife and supports important populations of plants and animal and makes it an ideal habitat for a good range of birds. The River Wensum is a tributary of the River Yare. Its source lies between the villages of Colkirk and Whissonsett in Norfolk. The river flows westward initially through the village of Raynham and through a number of small villages before flowing through the market town of Fakenham. From here the river flows east through the Pensthorpe Nature reserve and the village of Great Ryburgh to the villages Great Witchingham, Lenwade and Taverham before entering the City of Norwich where it merges with the River Yare before flowing eastward through Breydon Water to the North Sea at Great Yarmouth. The river is a designated Site of Special Scientific Interest (SSSI) and a Candidate Special Area of Conservation (cSAC) and much of the valley floor lies in the Broads Environmentally Sensitive Area.
