Before you go
Festival tips
Bring ID: S2O was for over-20s only in 2026 (being checked). Check each festival’s own rules on bags, phones and water guns before the day.
Outside the festival grounds the usual Songkran rules apply. Rules and fines.
Get home safely
Songkran 2026’s seven danger days saw 242 road deaths across Thailand (Road Safety Command Center via Thai PBS). Take the MRT or a taxi, never a scooter after a festival.
Seal your phone
You will be soaked. A waterproof pouch on a lanyard keeps your phone and ticket working.
Drink water too
Long days in the April heat and a lot of dancing. Pace yourself.
Medical emergency
Call 1669.
Where to stay for the festivals
Stay near the venue or near an MRT line, and you skip the late-night taxi hunt.
