The Duke and Duchess of Cambridge opted for a summer staycation with their children for the second year in a row, it has been reported.

Like many other families keen to avoid any travel restrictions, the couple are believed to have stayed in the UK and travelled to the Isles of Scilly with Prince George, Princess Charlotte and Prince Louis.

The family also headed to the islands off the coast of Cornwall, which are known for their beautiful beaches, for a break last summer too.

Their holiday destination was revealed by Hello! and the Cambridges may have stayed on the island of Tresco, which is privately owned.

Last summer, they were spotted cycling on the island and said hello to locals as they passed.

Speaking at the time, one holidaymaker said: “William and Kate were riding their bicycles, having a laugh. They looked so happy enjoying the weather.

“I did do a double take. They were really friendly and said hello.”

While a source told the Mirror: "They decided on a quick getaway before the children return to school. They were keen to support our travel industry.”

Prince William is no stranger to taking holidays on the Isles of Scilly.

In June 1989, he was pictured on the islands wearing shorts and a red jumper on a bike ride with Prince Charles, Princess Diana and Prince Harry.

And in 2016, William returned to the islands with Kate on an official trip, where they visited the island of St Martins as well as Tresco Abbey Garden.

It is also believed that Kate and William took the family to the Isles of Scilly last October and stayed in a modest cottage.

The Isles of Scilly are an archipelago of 28 islands off the southwest of Cornwall.

However only five of the islands - St Mary's, Tresco, St Martin's, Bryher and St Agnes- are inhabited.

Last month, Prince Charles and the Duchess of Cornwall, visited the islands of St Mary's and Bryher as part of an official visit to Cornwall.

Charles is the owner of the Duchy of Cornwall estate, of which the Isles of Scilly are a part.
