Inkpen and Walbury Hills is an 86.8-hectare (214-acre) biological Site of Special Scientific Interest south of Kintbury in Berkshire.

A Bronze Age cemetery of three bowl barrows on Inkpen Hill is designated a Scheduled Monument.

[1][2][3][4] These hills have the largest area of unimproved chalk downland in the county and much of it is managed by sheep grazing.

North facing slopes have many mosses and herbs, such as hoary plantain and germander speedwell.

There are also woods and hedgerows which provide a habitat for many species of breeding birds.
