Hundreds of festival-goers were left stuck in the mud this weekend after the carpark at Portmeirion's Festival No.6 flooded.
At one point as many as 18 tractors were being used to tow vehicles from the park and ride field, after a nearby river burst its banks.
Hundreds of people were forced to wait overnight in a nearby leisure centre, with members of the British Red Cross helping to provide welfare and refreshments.
In a statement on the Festival's website, organisers apologised and offered advice on what to do, including how to claim a refund.
The festival, which is now in its fifth year, hosted the likes of Hot Chip, Bastille and Noel Gallagher, but all some people on Twitter could talk about was the weather.
An official statement on the event's website said 90% of cars on the park and ride site had been exited, and that work was still ongoing to clear the site.
