Grouse Hunting
The Queen had access to the best of everything but she was a woman of simple pleasures. Her favorite hobbies involved being outdoors with her animals. Her ideal summer activity was grouse-hunting at her Balmoral or Sandringham estates. Here’s a video of the monarch on a hunting trip.

The Queen donned a less glamorous wardrobe than the public usually saw. She interacted with her dogs and fired shotguns at the birds. But the best aspect of this was being outdoors in nature. It was a fantastic respite from the pressures of her everyday duties (via Town And Country Mag).
