People leaving the All Together Now Festival have faced delays of up to an hour and 45 minutes just to get out of the car parks.
Posts on social media show long lines of beeping cars.
There was criticism on Friday after thousands of drivers found themselves stuck in cars for hours, as they waited to get into the carparks at the Curraghmore Estate in Waterford.
AA Roadwatch says Gardai are advising there's been a change to the exit routes for those leaving or collecting others today.
