We've seen the Duke and Duchess of Cambridge's three children reach many sweet milestones as they grow up, but there's one that their youngest child Prince Louis is still missing out on – his first royal tour.
The three-year-old royal has made a handful of public appearances, including his Buckingham Palace debut at Trooping the Colour in 2019 and his first Christmas church service in 2021, but Louis is yet to travel overseas on an official visit with his parents and siblings.

Overseas travel for the royals has been put on hold for much of the last two years due to the pandemic. The Duke of Cambridge recently visited Dubai in the UAE and the Duchess of Cambridge will carry out a two-day trip to Copenhagen in Denmark next week.
Prince William and Kate are also reportedly set to embark on a Caribbean tour this spring to celebrate the Queen's Platinum Jubilee.
It's not known if the couple will also be accompanied by their children, as this will depend on whether the visit takes place during term time. Prince George, eight, and Princess Charlotte, six, are currently in Years 4 and 2 at Thomas's Battersea School in south west London, while Louis attends Willcocks Nursery School in Kensington.

George travelled to Australia with William and Kate in 2014
In comparison, Prince George made his tour debut in Australia and New Zealand in 2014 when he was just eight months old.
The tot stole the show when he met his namesake George the bilby at Taronga Zoo in Sydney and was even given his own soft toy, which he was instantly enamoured with.

Charlotte made her tour debut in Canada in 2016
Prince William and Kate were then joined by their eldest children on their visit to Canada in 2016, where a 16-month-old Princess Charlotte made her royal tour debut.
The young royals had fun at a children's party in Victoria, British Columbia, where the Princess spoke her first words in public, as she ran towards a balloon arch and said, "Pop!"
George and Charlotte also accompanied their parents on a visit to Germany and Poland in 2017.
