The festival, which stands for help organize peace worldwide, is celebrating its twentieth year.
Those that turn out will be able to visit with 60 organizations, take in a kids program, and enjoy live entertainment.
Attendees are also asked to share their visions of what they want the world to look like in twenty years.
"It's a fun day and it's a way to learn and to find out what's going on. I think sometimes when we try to do things on our own, we look at how big the problems are in the world, it can feel overwhelming but when we come together at the HOPE festival we realize how many of us there are and we do have the power for real change," says program coordinator Ilze Petersons.
The HOPE Festival is free and will be held this Saturday from 11 until 4 at the University of Maine's Student Recreation and Fitness Center.
