Families turned out to Eaton Park in Norwich to raise as much money as possible for a charity which funds research into childhood brain cancer.
The charity Finnbar's Force organised the Jedi Walk in memory of five-year-old Finnbar Cork who died in 2016, five months after being diagnosed with a brain tumour.
The Jedi Walk took place today from 9.30am to 3.30pm, with everybody able to join in with the fun - whether it was to take part in the walk, enjoy the games or have a cake in the sun.
Around 20 people from Norwich Star Wars Club attended in full costume.
Finnbar's father Tristan Cork said: 'Just a year before Finnbar died, he had become a huge Star Wars fan and watched the films loads of times. A number of local schools celebrate May 4 in his memory by asking the children to dress up as Star Wars characters.
'The Jedi Walk is aimed at children who can dress up in Star Wars costumes, or anything they like, and join in a quest to find adults in Star Wars costumes hidden around the park.
'Once they have collected eight stamps they will have successfully completed their Jedi mission.
'Last year more than 225 children took part raising more than £1,500 for Finnbar's Force and we hope we can double that figure this year.'
Finnbar was a happy and active boy and a pupil at Hethersett Woodside Nursery and Primary School, enjoying life to the full.
He started experiencing dizziness and staggering when walking. After several trips to the GP, Finnbar was referred to the Norfolk and Norwich University Hospital.
His diagnosis was a low-grade astrocytoma brain tumour but a couple of months later it was changed to a more aggressive type.
Mr Cork and his wife Claire were given the devastating news that there was nothing that could be done to save their son.
To raise awareness of childhood brain cancer and to raise money to fund vital research, they set up the charity Finnbar's Force, a member charity of Brain Tumour Research, in their son's memory.
They are raising funds to find a cure for the disease which kills more children and adults under the age of 40 than any other cancer and invited families along to Eaton Park in the city over the weekend to raise money.
