21 Countries Kate Has Visited Since Joining the Royal Family

Kate's first solo overseas trip was supposed to have been to Malta in 2014, but William ended up going in her place as she was suffering from hyperemesis gravidarum during the early stages of her pregnancy with Princess Charlotte.

Instead, Kate's first solo trip was to the Netherlands in 2016, where she attended a round-table discussion with mental health charities, and visited the Mauritshuis museum. At the museum Kate came face to face with one of its most famous paintings Girl With a Pearl Earring by Vermeer — with Kate herself wearing a pair of pearl earrings on loan from the queen.
