The festival is notable for being a major event in the town of Caerphilly, attracting up to 80,000 visitors over three days.

[3] In 2022 the festival was hoped to make a return, but due to development work being undertaken at Caerphilly Castle the council announced they'd host an alternative event named Little Cheese Race.

The festival has previously included a Big Cheese Race, a funfair, firework displays, music and other forms of entertainment, including talks, demonstrations, educational activities, and activities for children.

[6][7] The Big Cheese Race follows a route around the castle with teams running in relay from the main event site.

The festival is held over a three-day weekend, starting on a Friday afternoon, and in 2012 it attracted around 80,000 visitors[9]
