On Friday, pumpkins were picked up by those participating in the event, which is UCP's largest fundraiser of the year.
On Sunday, Oct. 21, 29 pumpkin patches will be set up at Anah Shriners in Bangor, where kids will enjoy trick or treating, games and more.
Hundreds of hand-carved jack o' lanterns will also be on display.
If anyone would like to help, candy donations are always welcomed.
"We have candy bins at our office at 700 Mount Hope, and that's one of our biggest expenses, the candy that gets passed out at the event, so if anybody would like to make a candy donation they can do it that way," Pumpkins in the Park Chairman Andrew Lohman said.
Event sponsor Van Syckle Kia hopes folks will get dressed up and come support United Cerebral Palsy of Maine, which provides services to adults and children with mental and physical disabilities.
