The Princess of Wales was supported by her younger brother, James, on her descent from Yr Wyddfa (Mount Snowdon) over the weekend, new videos have revealed.
In heartwarming footage shared on social media, Kate, 44, can be seen holding onto James's hand for support as she completed her gruelling Three Peaks challenge.
The Princess was seen wearing red North Face shorts, a sporty cap, and a rucksack with water as she and James, 39, came down the rocky path from the summit stone.
The footage was captured by entrepreneur Phillip Tebajjwa, who was also climbing Snowdon at the weekend and thought he was "dreaming" after he bumped into the royal, who had also climbed Ben Nevis in Scotland and Scafell Pike in Wales.
Posting on social media, he wrote: "There I was, congratulating fellow climbers as they made their way down from the windy summit… little did I know I was actually speaking to royalty."
The lucky climber also managed to get a selfie with the Princess at the summit, adding: "The Princess of Wales has just stopped to congratulate me on completing the challenge… and then agreed to take a selfie.

Sharing a windy video from the summit, he said: "Okay, back to reality. That must have been a dream!"
Princess of Wales supported by family after Snowdon descent
At the time, it was shared that the Princess was met at the base of Snowdon by her family, including her husband, Prince William, and three children, Prince George, Princess Charlotte and Prince Louis.
Her parents, Carole and Michael Middleton, and younger brother, James, also met her to congratulate her.

While Kate completed the challenge solo, James helped escort her back to the base of the mountain.
The expedition, which saw her climb three peaks over 24 hours, was to raise funds for the Royal Marsden, where she had her cancer treatment.
The Princess announced she was in remission from cancer at the start of 2025.
James Middleton's message of support to sister Kate
After she completed the challenge, James commented two emojis – a mountain and a heart – underneath a photo of his sister at the top of Ben Nevis.
James, who is also known to love hiking and the outdoors, seemed to be fulfilling a long-standing promise to Kate.
He had shared a poignant message of support for his royal relative after she announced she would be undergoing chemotherapy treatment following her cancer diagnosis in 2024.

James and Kate have always had a very strong bond, with the royal previously supporting her brother through his battle with depression.
He previously told HELLO! that he felt like he had "three mothers" growing up – the family's matriarch, Carole, as well as sisters Pippa and Kate.
James, who lives in Berkshire, is married to Alizee Thevenet, and the couple share a two-year-old son, Inigo.
