Salisbury Plain is a chalk plateau in the south western part of central southern England covering 300 square miles (780 km2). It is part of a system of chalk downlands throughout eastern and southern England formed by the rocks of the Chalk Group and largely lies within the county of Wiltshire, but stretches into Hampshire.
Beacon Hill is near the village of Burghclere and Watership Down, in north Hampshire. The hill's name is derived from the fact that it was one of many Beacon Hills in England and beyond. This hill was once the site of the most famous beacon in Hampshire. It is 261 metres high and has one of England's most well known hill forts on its slopes, visible from the main A34 road which passes close by. From there, outstanding views of the surrounding area and much of Hampshire may be obtained. The site is open to the public and managed by Hampshire County Council. It is an 80.7-hectare (199-acre) biological Site of Special Scientific Interest called Burghclere Beacon and a Nature Conservation Review site, Grade I.

A biological Site of Special Scientific Interest, notified in 1971, covers 1.5 hectares of the site; this designation is due to the site's species-rich plant and insect communities, which include some rare species. Notable among these is the musk orchid, which has been confirmed at only one other site in Wiltshire.

The moors are asserted to be of national importance by Natural England for the extent, quality and diversity of upland types including heaths, fens, wet grassland, flushes, mires and blanket bogs, together creating an extensive mosaic habitat supporting an exceptional community of amphibians. The moors are important, too, for their relict juniper woodland and scrub.
