S2O is marking a decade of music and water, and this year’s edition is set to be its most ambitious yet. Known for its large-scale production and crowds, the festival is stepping things up with new features, enhanced effects, and a lineup filled with major names in dance music.

This year’s headliners include Marshmello, Alan Walker, DJ Snake, Timmy Trumpet, Major Lazer, and Diplo, alongside a mix of international and regional talent. With three days of performances, the festival will bring a variety of electronic music styles to the stage.

- What’s New for 2025?

S2O isn’t just getting bigger. This year, it's introducing new elements never seen before at the festival:

- 360° Water System

S2O has always been known for its water experience, but this year, it's going further with a completely redesigned water system. The setup will now spray from multiple directions, ensuring that every part of the crowd stays drenched throughout the festival.

- Brand-New Interactive Activities

This year’s edition will introduce exclusive activities that have never been done at any festival before. While organizers have yet to reveal the full details, these additions will bring a new way to experience S2O beyond just the music and water fights.

- Dedicated Dry Zone

A dry zone will be available for those who want to enjoy the festival without getting soaked. Whether you’re looking to stay dry for photos or just want a break from the water, this section provides a different way to experience the event.

- Improved Transportation Services

To help with crowd movement and make entry and exit smoother, S2O has partnered with Grab to provide on-site ride-hailing services. Shuttle buses will also be available at designated pickup and drop-off points to make traveling to and from the venue easier.

S2O 2025 is introducing new ways for festival-goers to enjoy the event while keeping everything that makes it a must-attend Songkran experience. With an upgraded water system, new activities, and better accessibility, this year’s edition promises to be bigger than ever.

With a sold-out crowd each day, this year’s edition is set to be the biggest yet. The stage has been completely redesigned, production has been upgraded, and the expanded venue at Rajamangala National Stadium will welcome over 120,000 attendees across three days.
