A row has been rumbling on for years over the decision by Telford and Wrekin Council to only open the Bowring Park car park when there is a booking in the pavilion.
It says it is an agreement that was made with local residents after anti-social behaviour on the car park accessed off Herbert Avenue.
But Bowring Park users say opening it every day would stop the congestion of parking on residential streets.
Facilities in Bowring Park which has its main entrance in Haygate Road, include tennis, cricket and football pitches, as well as children’s play areas, bowing greens and an outdoor gym,
The organiser of Tuesday's protest, Mr Paul Kalinauckas, said the last petition handed into Telford and Wrekin Council calling for the car park's daytime opening attracted 1,000 signatures.
"Bowring park is a real community park and attracts so many visitors, both local and from further afield.
"It seems a nonsense to have a car park right next to it but for it only to be open when the building is booked out."
"Volunteers have come forward to say they will open and close the car park morning and night."
Those taking part in what they called a peaceful protest on Tuesday held placards calling for the opening of the car park.
Telford and Wrekin Council has been asked to comment.
