Heineken Stage

Live your music in our HEINEKEN STAGE. It is the only place at the festival, where you can enjoy a perfectly served, cold Heineken with a close view of the Main Stage. Between concerts you can relax and have fun taking part in our activities. After the sunset, we invite you to Heineken Stage to see performances by well-known, polish DJs.

On top of that, remember that you can enjoy beer at the concert near the stage thanks to Heineken3 (lower alcohol content beer). Heineken 3 will be available in specially branded points of sale.

See you there!

This year, we will "turn up" the summer and we show that music and summer festivals are a great time for crunching together.

No matter what music genre you like most - there are as many of them as Lay's flavors. You will find this diversity in our Lay's zone, where variety of activities is waiting for you -  ideal for you and your (not only) music pack! )Music neon room, festival tattoos, comfortable chill zone or the opportunity to take the most instagram-worthy photo at the festival (how many hearts will you collect?).

What do we have, you’ll ask? Only the best, we will answer. Dragons Lair? Got it. Donkey Kong? Here. Stargate? Sure. Dig Dug? Yup. Even with Mad Max's record. Do you think you can beat it? Then you will get out of the festival on a bike. Literally. Not exactly thou. We will deliver the bike to your door by courier.
