The event, organised by North Kesteven District Council took place in the Market Place on Saturday, October 25 when youngsters could dress up, bring the family, and enjoy a day full of autumnal excitement.
Visitors could collect one of 200 free pumpkins.
Pumpkin carving stencils could be crafted to take home and send in a photo of their carved creation with a chance to win a local hamper filled with goodies.
There was walkabout comedy entertainment by Trick and Treat, free face painting and craft activities, Morris dancing performances, and a live pumpkin carving demonstration by Simon McMinnis.
And visitors could meet the Sleaford Wyvern – a mythical dragon – as a striking inflatable installation linked to the wyvern railings sculpture in Monument Garden.
There were also giant games and you could find out more about the upcoming food waste collection service, which will roll out in March 2026.
