There'll be music on three stages at the Abersoch site
Feeder, Plan B, N-Dubz, The Ting Tings and Eric Prydz are among the line-up of top bands and DJs, as well as homegrown talent, at this weekend's Wakestock Festival in Pwllheli and Abersoch.
The event sees thousands of fans flock to this small corner of the Llŷn Peninsula, with coverage on TV and radio for those who can't make it.
BBC Radio 1 DJ Huw Stephens, said: "Each year the festival grows, with so many visitors flocking to Abersoch to look for a good time and to hear some great music.
"The organisers always manage to create a memorable event by attracting the best bands of the moment and the up and coming bands to the area.
"I'll be DJing again among all the great performers from Wales and beyond."
Bangor band Yr Ods will be performing and lead singer Griff Lynch is looking forward to returning to Wakestock.
Free shuttle buses will run between the festival and wakeboard sites
"Each year the standard of the bands gets better and better and it's a great platform for Welsh bands to show their talents next to world-renowned bands and artists," he said.
Yr Ods have just performed at Glastonbury for the second year running and after Wakestock are planning to be on the road over the next few months, going from festival to festival.
For BBC Radio 1, Huw Stephens and Tom Deacon will broadcast live on Saturday, 1pm-4pm.
The show promises to be an unusual but entertaining live broadcast where the DJs will pick up some tricks and skills in some wakeboarding lessons, go on a tour of the site and get some exclusive backstage interviews.
Huw and Tom will also be moored on a boat from where they plan to provide a fast-paced commentary as 20 of the world's best wakeboarders battle it out on the Pwllhelli Marina.
Police have warned they will be cracking down on under-age drinking throughout the weekend.
Supt Mark Owen, based in Caernarfon, said they would be making test purchases of alcohol in partnership with Gwynedd Council, the Welsh Ambulance and the organisers.
"Last year a lot of young people were very ill after consuming alcohol and most of the cases dealt with by the ambulance service were alcohol-related," he said.
"We just want people to come and have a good time and enjoy the event, but at the same time to stay safe."
Food and alcohol will be on sale inside the venue, but those who look under 21 may be asked for proof of age. Acceptable forms of ID will be a photo driving licence or passport.
No food or drink can be taken into the site, apart from 500ml of water in a plastic container with an unbroken seal.
TV coverage is on S4C, Saturday and Sunday, 3 and 4 July, 6.30pm and 9.30pm.
