5 Memorable Royal Trips Kate Middleton Carried Out Without Prince William

On October 11, 2016, the then Duchess of Cambridge embarked on her first solo official trip abroad to the Netherlands, emphasizing diplomacy and charity. She met King Willem-Alexander, visited the Mauritshuis museum for a Vermeer exhibition, and participated in a roundtable on mental health at the British ambassador's residence.

The then Duchess of Cambridge visited Luxembourg on May 11, 2017, to mark the 150th anniversary of the Treaty of London, which secured the country's independence. This was her second official solo visit, which sought to enhance UK-Luxembourg relations through soft power and included commemorations with the Hereditary Grand Duchess, cultural visits, and interactions with locals. It was part of a UK government initiative to maintain European ties during Brexit. Kate donned a pastel-blue Emilia Wickstead coat dress on the trip that strengthened diplomatic relations.

Kate, who is the patron of the Rugby Football Union, attended the 2023 Rugby World Cup in France, supporting England during key appearances in September and October. Notably, she was present at the England vs. Argentina match on September 9 in Marseille, looking stunning in a white Alexander McQueen trouser suit.

In 2022, Kate spent two days in Denmark promoting her Early Childhood Foundation. In Copenhagen, she interacted with Princess Mary to support domestic violence initiatives and met researchers from the Copenhagen Infant Mental Health Project. The LEGO Foundation Playlab was another stop on her agenda. She intended to gain knowledge about Denmark's approach to early childhood development and to exchange ideas on incorporating scientific findings into parental techniques.

Kate will visit Italy on May 13-14, 2026, focusing on the "Reggio Emilia Approach" to early childhood development for the Royal Foundation Centre for Early Childhood. This marks her first official overseas trip, following her cancer diagnosis. Traveling solo, she intends to incorporate this Italian methodology into her "Shaping Us" framework and also promote her passionate cause.
