The national event, an idea from the Eden Project, saw a funfair, bouncy castles and an inflatable assault course come to the park.
There were also crafts and a range of food stalls featuring food from around the world, including Indian, Italian, and Greek, complete with popcorn, ice cream, and candyfloss.
Our photographer Michelle Adamson went along to grab these pictures.
