Party in the Universe is the theme at Bangkok's biggest Songkran festival

S2O Songkran Music Festival earns its reputation without trying too hard. For 2026, it shifts to a purpose-built site on S2O Land, Ratchadaphisek, trading up for a wider footprint and sharper production under the theme Party in the Universe. The signature 360-degree water cannons stay, firing in sync with each drop, though the timing still catches you off guard. Between sets, fireworks cut across the night, while the lineup leans heavily on familiar headliners rather than surprises. And just when it seems enough, K2O Festival extends the weekend by another day, for anyone not quite ready to leave.

April 11-13. B3,500-7,900 via here. S2O Land, 5pm onwards
