Mountains of rubbish were littered across the Quarry Park after hundreds of people enjoyed picnics meeting up with friends and family over the Easter weekend.
The security company, Prosecure 2000 which patrols the Quarry, posted a video on Twitter, showing some of the mess that had to been cleaned up.
Town Councillor for the Quarry and Coton Hill, Councillor Nat Green, urged people to take their litter away with them.
"We are truly blessed in Shrewsbury to have such wonderful places like The Quarry and other green spaces.
"We would urge everyone who used our green spaces to treat them with respect so that they can be enjoyed by everyone. Please take your rubbish home with you."
A spokesman for Prosecure said: "We all want to enjoy the fresh air, see our friends and families again in such a lovely location, but please be considerate to others."
The park has been extremely busy since lockdown rules changed to allow two households or groups of up to six to meet outdoors.
Police have also been called to disperse larger gatherings and used a dispersal order last week.
