You'll find the AONB on the Essex-Suffolk border, in the heart of East Anglia. The designated area of the AONB is just 90 kilometres square and stretches upstream from Manningtree to within one mile of Bures. The remainder of the Stour Valley landscape is mostly of as high a quality as that within the AONB designation, and representations to extend the AONB continue.
The dark green areas of the map below represent the AONB designation, whilst the light green area reflects the extended project area of the Stour Valley. You can download a copy of the map here.
