Pictures shared on social media showed Woodhouse Moor in Leeds covered in litter after people went home people from enjoying the sunshine on Tuesday.
Bottles, plastic bags and cans were left lying in the grass after hundreds of people went to the park in the city’s Hyde Park area as temperatures soared to 21C in the city.
A council crew arrived at the park early on Wednesday morning to begin the clean-up operation.
A local resident, Dean Blackie, told Leeds Live: “I understand the need to get out and socialise but it really isn’t hard to take your rubbish with you… that’s diabolical.”
A spokesperson for Leeds City Council urged people to continue to follow the rules on social distancing and gatherings, saying that “it is vitally important if we are to continue to protect the health and wellbeing of ourselves and others”.
Meanwhile in Liverpool’s Sefton Park, mountains of cans and bottles were heaped near rubbish bins and patches of grass were left burnt by disposable barbecues.
According to the Liverpool Echo, a clean-up operation is now underway with council refuse workers clearing up litter across the park.
