Hundreds of cars are stuck in the mud at the Electric Picnic in Stradbally, Co Laois.
Heavy rain over night has left the fields where cars were parked very wet. Tractors are being used to tow out some vehicles.
Traffic in and around Stradbally is extremely heavy with the Abbeyleix road particularly bad.
Meanwhile GardaÍ are cracking down on drink driving as revellers head home.
There have been a number of arrests this morning following on from six others over the weekend.
