Kicking off at 2pm, the event – known as the Universal Water Fight Championships – will see two teams battle it out, armed with supersoakers and water bombs.
The theme for this year’s festival is ‘The Gardeners Guide to the Galaxy’ and attendees are encouraged to come dressed in space-themed outfits. Those with the best outfits will be rewarded with prizes from the Secret Garden Party team.
Though exact details are under wraps, so far over 800 people are signed up to attend the event.
The festival will take place from 21-24 July in Cambridgeshire. Headliners include Caribou, Air and Primal Scream.
Hunter hosted its inaugral festival summit with Google, EE, Live Nation and JWT last week. Findings included an 11% growth in festival-related searches in 2015.
