The Benfield Valley area is in the west of the city on its northern outskirts, between Hangleton and north Portslade.
The site known as Benfield Valley is located between the Old Shoreham Road, the A27 by-pass and the A293 Hangleton Link Road. It forms a green wedge which stretches from the urban area to the south up to a border with the A27 and South Downs National Park to the north.
Parts of the site are used for formal and informal recreation. The northern part of the valley is currently used as a footgolf course.
The Sainsburys superstore and car park is located towards the south of the valley, with a recreation ground including playing pitches at the very southern end. Greenleas recreation ground and Hove Park School are located to the east. There are public rights of way across the valley.
Benfield Barn is located towards the north of the valley and is a grade II listed building. The Barn together with the historic outbuildings and flint walls in the vicinity of the Barn comprise the Benfield Barn Conservation Area.
The northern part of Benfield Valley, north of Hangleton Lane, also lies within an archaeologically sensitive area, where historic remains may exist.
