Kate, Prince William and their children Prince George and Princess Charlotte are staying at the Queen's estate in Scotland
Granny’s in charge!
The monarch wore a casual look which featured a green vest over a navy blue blouse. (Sadly she was not wearing one of her favorite country accessories – a silk headscarf.) Kate meanwhile looked like the epitome of English country chic in a green jacket, brown scarf and her long brunette locks pulled back in a tortoise shell-patterned headband.
Prince William, who had been out on a grouse shoot near Loch Muick on Saturday, had gone up ahead of the Queen and Kate. Then the Queen was spotted by walkers.

“They looked really happy,” a local tells PEOPLE. “They were coming up to see the others for a picnic when the shoot had its break.”
The royal party was photographed about five miles from the Queen’s Balmoral Castle, but still on the estate. The Queen drove Kate to a remote part of the estate to meet with William for a picnic.

The couple is expected back in England later this coming week, as on Friday they are visiting a school just outside London to highlight their mental health campaign Heads Together, at a time when youngsters feel the pressures in the first weeks of starting school.
The extended royal family often makes the trip to Balmoral at least once during the Queen’s month-long vacation. Princess Anne is residing on the estate while she recovers from a bad chest infection that forced the hard-working royal to cancel her official engagements. Prince Harry will also reportedly make an appearance at the Scottish estate after he returns from his six-week charity expedition in Africa on Thursday.
