Kate revealed to the assembled crowds that she and William had taken their children, Prince George, six, Princess Charlotte, five, and Prince Louis, two, on a holiday to the Lake District during a half-term break.
The classic UK destination is much loved by the royals.
One well-wisher at the Keswick walkabout told Hello! magazine: “She said that her children love coming here and walking in the fells.
“She told us how nice the Lake District was and how lucky we were to live so close to the mountains.”
Both Kate and William enjoy the outdoors.
The Duchess has previously she loves spending time among nature with her children.
William spent his own childhood enjoying rambling holidays.
He and his brother Prince Harry, 35, used to be taken litter picking by father Prince Charles, 71.
It is not known where the Royal Family will spend their summer holiday this year.
Many Britons are opting to stay in the UK for their break amid the uncertainty of foreign travel.
It is quite possible the Cambridges – who live in Norfolk – will decide to do the same.
It’s likely Kate will be keen to meet up her parents over the summer holidays.
She said recently during a visit to Fakenham Garden Centre that she hasn’t seen her family, the Middletons, since before lockdown.
The Duchess commented: “I’ve yet to see my family as they’re about three hours away in Berkshire, so I haven’t seen them and I miss them.”
