Although the ceremony takes place inside the Castle for which tickets are required you can watch the Guards, normally led by a Regimental Band, as they march to and from Windsor Castle.
Traffic is stopped, transforming the bustling High Street into a parade route lined by residents and visitors waiting for the Band and Guards to march past on their way to and from the Windsor Castle Guard change.
The steps of Guildhall, being slightly raised, is a popular spot, where you can get some great pictures of the Guards as they march past on their way to and from Windsor Castle, but good views are available along the entire route.
At approximately 10:45 hours the New Guard, normally accompanied by a Regimental Band or Corps of Drums, step off from Victoria Barracks, they march up Sheet Street, wheeling left into the High Street, past the Parish Church and the Guildhall, then wheel right onto Castle Hill, by Queen Victoria's Statue, and enter the Castle through the Henry VIII Gateway.
During Easter Court and Ascot Week find a spot on the opposite side of the road to the Castle, near the junction with St Albans Road, to see the Old Guard leave the Castle through the Henry VIII Gateway, between 10:40-10:45, turning, left they march up Castle Hill and back into the Castle.
Soon after the New Guard, led by a Regimental Band will march past you on their way up the hill to the George IV Gateway.
After the Guard Mount ceremony the 'Old Guard' and Band return to Victoria Barracks, following the same route in reverse.
Photographs by David Whitecross, taken along the route the Guards march
A tip, from David Whitecross our photographer in Windsor;
"To see more and get some great pictures head for Victoria Barracks then follow the Guards up Sheet Street and along the High Street, on the Parish Church side then a quick dart through either through Market Street or Church Street, to right of the Guildhall, will bring you to Castle Hill as the Band is still turning round the Queen Victoria statue".
"During Easter Court and Ascot Week follow the New Guard as far as the Irish Guards Memorial then turn right, past the old wishing well, into St Albans Road, (which runs parallel to the High Street), where, a brisk walk will bring you to Castle Hill where you will be able to see the Band and Guards marching up to the top of Castle Hill."
Traditionally His Majesty The King stays at Windsor Castle over the Easter period, known as 'Easter Court'.
During this period, the Windsor Castle Guard march to the top of Castle Hill and enter the Castle through the St George's Gate to change the guard on the lawn of the Quadrangle.
