Sandhurst is bordered, on the south, by the River Blackwater, and several of the Yateley Lakes along its course are within the parish, notably Trilakes with its country park.

The town of Crowthorne is to the north, the village of Finchampstead to the west, and Camberley, across the Surrey county boundary, is on its southeastern side.

[7] Stagecoach South operates bus route 3 between Yateley and Camberley every 15 minutes except on Sundays; alternate services extends to and from Aldershot.

[10] In the early 14th century records, Sandhurst appears as part of the township of Sonning, a large minster parish spreading over much of eastern Berkshire,[10] which later became a hundred when its villages obtained their own churches.

[11] Locals had the right to cut turf, bracken, heather and wood that was primarily cultivated to feed the forest deer.

[citation needed] Life changed very little in Sandhurst until the 19th century when large sections of land were sold for the building of the Royal Military College, which moved from Marlow in 1813.

[10] The railway arrived in 1849 and a number of large country residences were subsequently erected in the area: amongst them, Harts Leap,[10] Forest End, St Helens, The Uplands, The Warren, Longdown Lodge, Ryefield, Snaprails, and Ambarrow Court.

Sandhurst Lodge was erected in about 1858 by Robert W. Gibson and leased to John Walter, of the Times Newspaper, and then Sir William Farrer, solicitor to Queen Victoria[10] and The Duke of Wellington.

Such large houses and institutions, including the Broadmoor Hospital and Wellington College in nearby Crowthorne, led to a great expansion of the local population as people moved into the area looking for work.
