The Duke of Cornwall, 70, will carry out a whopping 20 engagements across Wales this week with his wife Camilla.
The tour will mark the 50th anniversary of Charles’ investiture as Prince of Wales at Caernarfon Castle on July 1, 1969.
The Queen had first bestowed him with the title when he was just nine-years-old on July 26, 1958, before formally investing him 11 years later.
But while he embarks on a week of visits, Daily Star Online recently revealed how he has also been stepping up preparations for becoming King.
We reported how Prince Charles has been attending meetings in preparation to take over from the Queen.

When he becomes King, he will have to take over the running of the monarch’s £533million Duchy of Lancaster estate which provides income for the sovereign.
This is a massive private estate consisting of a portfolio of lands, properties and assets which generated the Queen £20million in income last year.
It boasts 45,550 acres of land across England and Wales, and holds ownership of the 734-year-old Savoy Estate in London’s West End between the Strand and the Embankment.
Daily Star Online found Charles, who had already been attending meetings of the Duchy, had attended another one in February.
An entry in the Court Circular – the Royal Family’s official diary – shows he held the meeting at his Clarence House home on February 6.
The discovery came after we also revealed Charles and Camilla will move into Buckingham Palace when the Prince takes the throne.
In the meantime, Charles’ tour around Wales this week will mark 50 years since the day of pomp and ceremony which saw him crowned Prince of Wales.
The ceremony was televised and watched by a massive audience of 19 million people across the UK, and millions more worldwide.
A fresh-faced Charles – who is now the longest-serving Prince of Wales and heir apparent – knelt before the Queen to receive the insignia of office and pledge allegiance.
While the prince was saluted by cheering crowds showing their loyalty and affection, he also faced hostility from Welsh extremists who attempted to mar the investiture with a spree of bomb attacks.
The day had started with news that two men had died in a gelignite explosion at Abergele, 15 miles from the castle.
One of the men was tattooed on his chest and back with “Free Wales Army”.
Then, a bomb blast at railway sidings rattled windows in the centre of Caernarfon 10 minutes after the arrival of the train carrying the Queen, the Duke of Edinburgh, Charles and other members of the royal family.
A bomb in a suitcase, marked with the initials “FWA”, was later found on the road to Holyhead taken by the prince after the ceremony.
Then, in the early hours of July 2, a soldier died when an explosion wrecked an Army van only yards from the castle.
But 50 years on, relations have improved as Charles now prepares for the day he becomes King.
Earlier this year, at a Buckingham Palace reception marking the anniversary, the Archbishop of Canterbury spoke of Charles’s enduring love of Wales.
The Most Rev Justin Welby said: “The investiture was unique. Seldom can a coming-of-age have had such a setting; seldom can the weight of expectation have been so great.
“In years since then, we have seen how the honour of being granted that title has been richly repaid – in the Prince of Wales’s love for the country whose name he bears, and in the deep respect he has always shown for the land, for the language, and most of all, of course, for the people.”
