Walbury Hill is a hill which is the highest point of both the historic county of Hampshire, England and the modern ceremonial county of Berkshire, England. At above sea level, it is also the highest natural point in South East England (West Berkshire being a constituent part of this region), higher than Leith Hill in Surrey. Although traditionally the county top of Hampshire, the summit of Walbury Hill was placed under the administration of the former Berkshire county council when the civil parish of Combe was transferred from Hampshire in 1895. The historic border between the two counties near Walbury Hill runs along the Wayfarer's Walk, a long-distance footpath which lies about north of the triangulation pillar at the summit. The highest point of the historic county of Berkshire lies along this footpath, at a height of above sea level on the northern flank of the hill.
