The family are understood to have stayed on Tanera Mor, a secluded private island in the Summer Isles

Prince Harry and Meghan Markle took Prince Archie and Princess Lilibet to a Scottish island during their recent visit to the UK.

Despite having once described Balmoral as "simply paradise," Prince Harry has yet to bring his two children to the private royal estate in Aberdeenshire.

Yet the Duke and Duchess of Sussex quietly whisked Prince Archie, seven, and Princess Lilibet, five, to a different Scottish destination earlier this month.

The family stayed on Tanera Mor, a secluded private island in the Summer Isles, owned by billionaire hedge fund co-founder Ian Wace, according to the Mail.

The visit, which was kept under wraps, took place during a broader trip to the UK that included several significant family engagements.

Wace, 63, acquired the 800-acre island, which is the largest of the Summer Isles, for £1.7 million in 2017, when it was home to just five residents and dotted with crumbling crofters' cottages.

He has since invested tens of millions in its regeneration, planting 100,000 trees, renovating a dozen buildings and constructing three miles of new roads.

A key feature of the island's revival is the Taigh Mor Foundation, a charity supporting armed forces and emergency services personnel.

By last year, more than half of the island's 1,000 guests had come through the foundation, taking part in activities such as building restoration, seaweed harvesting and fishing.

Wace, the co-founder of Marshall Wace, has maintained a friendship with both Prince Harry and Prince William over many years.

His former wife, the ex-model Saffron Aldridge, 57, developed a close rapport with Meghan, 44, after the American actress relocated to Britain.

The two couples attended a Cirque du Soleil show together at the Royal Albert Hall in 2019, the year following the Sussexes' wedding.

Meghan was said to have valued Aldridge as "a straight talker," with a shared passion for fashion further cementing their bond.

Wace and Aldridge separated in 2023 and have since divorced, though they remain on good terms.

The family is understood to have travelled to Scotland from Northamptonshire, where they had been guests of Earl and Countess Spencer at Althorp, the ancestral Spencer estate.

During their stay, the Sussexes placed flowers on the grave of Harry's mother, Diana.

Harry, Meghan and their children joined Charles and Queen Camilla for tea at Highgrove, the royal residence in Gloucestershire.
