The trip marks a celebration of Malta's 50th anniversary of independence from Britain, and Wills has a fully packed schedule to complete while he's there.
On day one, he was greeted by Malta's President Marie-Louise Coleiro Preca, and given a tour of her official residence, The San Anton Palace.
She said that she'd love to see Prince George in Malta in the future, to which William joked: "Malta might not survive Prince George. There's too many precious things around here."
He also gave an update on Kate's health, admitting: "She's so-so, She's very disappointed she couldn't be here today."
William also met the Prime Minister, Joseph Muscat, his wife Michelle and their twin daughters. He told them: "I'm sorry you've got me instead of Catherine. She's very disappointed she couldn't be here today."
The tour was to be Kate's first solo royal tour. But Clarence House officially announced that the pregnant Duchess was too ill to undertake the trip, tweeting: "The Duchess of Cambridge will no longer visit Malta this weekend. The Duke of Cambridge will undertake the visit instead #RoyalVisitMalta."
They also explained: "HRH continues to suffer from Hyperemesis Gravidarum. The decision was taken on the advice of doctors #RoyalVisitMalta."
Get well soon, Kate! And perhaps Clarence House should lose the hashtags.
LOVE PRINCE GEORGE? Here's his cutest moments, so far...
