The reserve is close to Sapperton and Frampton Mansell, and about two miles east of Chalford. It lies south of two other nature reserves: Siccaridge Wood and Daneway Banks, the latter a Site of Special Scientific Interest. The Sapperton Valley reserve is a long ribbon of canal bank, water meadows and woodland by the disused former Thames and Severn Canal. The River Frome runs parallel to the old canal and is the boundary to the reserve on its south side. The reserve is about a mile long. The canal was built originally to link the Stroud mills which supported the woollen trade, and was opened in the late 18th century. The length from Whitehall Bridge to Lechladeclosed in the early 20th century. A road bridge is the western end of the nature reserve; access to the reserve is along the towpath. There is some space for vehicles south of Daneway Bridge. The canal construction included a long tunnel, deep locks, bridges, a loading basin and the Daneway Inn, built to accommodate the men working on the tunnel. The Sapperton Valley is considered to be an important wetland area, situated as it is between the Frome and the canal. There are a series of wet meadows and this area is damp, generally undisturbed and overgrown, supporting wildlife. A diversity of habitats are thus concentrated in a relatively small area and range from ancient woodland to wetland. The 2005 Stroud DistrictLocal Plan identified the valley as a Key Wildlife Site.
The meadow areas are cut at the end of the summer to control the more dominant species. This practice supports the increase in the range of flowers.
Walks
There is a publication which details walks for recreation and observing wildlife in the Golden Valley. This includes information on Sapperton Valley and four other nearby nature reserves being Strawberry Banks SSSI, Three Groves Wood, Daneway Banks SSSI and Siccaridge Wood. The walk also includes other ancient woodland at Peyton's Grove, Oakridge village, Bakers Mill and Reservoir, Ashmeads Spring, and part of the route of the old Thames and Severn Canal.
