"National Picnic Week was created to inspire families, friends and couples to celebrate our outdoor locations by taking a picnic.
"The best days out are a combination of good people, good food and good weather.
"Luckily we’ve been having fantastic weather so far this Summer so if you haven’t already had a picnic this year, get out there while the weather is still good.”
