The Prince of Wales will meet Northern Ireland’s political leaders ahead of a full day of engagements in the region.
The private and separate meetings with First Minister Arlene Foster and Deputy First Minister Martin McGuinness will begin a packed schedule for the heir to the throne.
The Duchess of Cornwall will join Charles later on Tuesday for a number of visits to local businesses and places of interest.
In the evening, the royal couple will also host a musical evening at Hillsborough Castle.
On Wednesday, the Prince and Duchess will travel across the Irish border to Co Donegal.
The visit to the Republic of Ireland is at the request of the Government and follows Charles and Camilla’s trip to the country this time last year when the Prince toured the place where his great-uncle, Lord Mountbatten, was murdered by the IRA in 1979.
A Clarence House spokesman said: “The visits will recognise the warm friendship that exists between both countries, promoting understanding of their respective heritage and celebrating the best that each has to offer.”
Charles arrived in Northern Ireland on Monday, when he was given a glimpse into the high-tech world of internet security during a visit to Queen’s University’s first Global Research Institute at the Science Park in Belfast’s Titanic Quarter.
