King Charles and Queen Consort are to arrive in Edinburgh today ahead of The Queen's coffin procession to St Giles.
His Majesty the King and wife Camilla will fly to the capital this afternoon as Scotland prepares to say their final goodbyes to Queen Elizabeth II.
Upon the Royal family's arrival at the Palace of Holyroodhouse, His Majesty The King will inspect the Guard of Honour.
As is tradition, The King will be welcomed to His Majesty’s ‘ancient and hereditary kingdom of Scotland' by the Lord Provost, before symbolically receiving the Keys of the City of Edinburgh.
King Charles and senior members of the Royal family will then follow the Queen's cortege in procession along the Royal Mile to St Giles' Cathedral..
The cathedral will host a service to celebrate Her Majesty's life and her connection to Scotland.
The Queen will lie at rest there until Tuesday afternoon.
Mourners wishing to pay their respects to the late Queen will be able to view her coffin from 5pm.
A queuing system will be in place with security checks and restrictions on mobile phones will apply. Photography and recording is strictly prohibited.
People have been warned they face long waits due to the anticipated demand.
Officials say weather conditions may be challenging and standing for a number of hours should be expected.
A post on the Royal Twitter account last night read: "Her Majesty The Queen’s coffin has travelled from Balmoral Castle to the Palace of Holyroodhouse.
"Tomorrow a Procession will convey the coffin to St Giles’ Cathedral, where it will lie at rest to allow the people of Scotland to pay their respects."
The events are set to be "truly historic" according to Lord Lieutenant of Edinburgh, Robert Aldridge.
He said: "The news of Her Majesty The Queen's passing has been met with great sadness around the world and has been greeted with an outpouring of emotion that reflects how highly regarded she was at home and abroad.
"I'm preparing to warmly welcome King Charles and royal family members and of course to express deepest sympathy on behalf of the city.
"The next few days will be truly historic for Edinburgh, with tens of thousands of people descending to pay their respects and millions more across the world tuning into the broadcast coverage.
"I believe Scotland can take real pride that Her Majesty cherished her time here and now the eyes of the world will be upon the Capital as we unite in national mourning and herald our new King.
"This is a time for our communities to stand together and for people to reflect on our shared history. The outpouring of grief from citizens and visitors is touching and demonstrates the special relationship the city shared with the Queen.
"Edinburgh's Books of Condolence have been opened online, at the Central Library and across the city for citizens and visitors to pay their respects."
Leader of City of Edinburgh Council, Cammy Day, said he was "proud" the Scottish capital will play such a significant part in the ceremonial events over the coming days.
