The Princess of Wales has shared intimate new photographs capturing the moment she reunited with her family after completing the National Three Peaks Challenge, a demanding endurance event she undertook to support the hospital where she received cancer treatment .

In images released on social media Sunday, Catherine, 44, is seen embracing her husband Prince William and their three children—Prince George, 12, Princess Charlotte, 11, and Prince Louis, 8—at the base of Snowdon in Wales following her successful climb . The heartwarming photos also show the princess with her parents, Carole and Michael Middleton, and her brother James, who joined the family celebration .

The future queen completed the challenge, which involves scaling the highest peaks in Scotland, England, and Wales—Ben Nevis, Scafell Pike, and Snowdon—within 24 hours. She covered approximately 23 miles on foot with more than 10,000 feet of elevation gain, becoming the first member of the royal family to achieve the feat .

In her social media post, Kate wrote: "This time last week, completing the National Three Peaks Challenge. A huge thank you to everybody who has supported The Royal Marsden Cancer Charity" .

The challenge carried profound personal significance for the princess, who underwent cancer treatment at The Royal Marsden before announcing she was in remission in early 2025 . She previously described the trek as "a chance to explore life beyond diagnosis" and an opportunity to raise awareness about the emotional, psychological, and spiritual impact of serious illness .

Kate undertook the challenge solo, supported along the route by Mountain Rescue teams . Kensington Palace confirmed her participation marked a royal milestone, with the princess becoming the first member of the royal family to complete the demanding expedition .

The newly released photographs capture tender moments, including Kate placing a reassuring hand on George's shoulder, embracing Charlotte warmly, and holding Louis's hand while speaking with her husband . One image shows the entire extended family gathered together at the finish line .

During the climb, the princess encountered 11-year-old Ted, a wheelchair user completing the same challenge with family and friends to raise funds for a children's charity. Kate later donated to his fundraising page, describing him as one of the "real highlights" of her experience .

Her brother James also shared an emotional tribute, recalling a promise he made while Kate was in hospital that they would "climb this mountain together" .
