Bangkok, 25 October 2025 – The Tourism Authority of Thailand (TAT) has announced adjustments to the schedule and format of its planned activities during October–November 2025 to express respect and gratitude for the royal grace of Her Majesty Queen Sirikit The Queen Mother, following the Royal Household Bureau’s announcement on 24 October 2025 regarding Her Majesty’s passing.

TAT has carefully reviewed all planned tourism activities during this period and adopted three key measures: postponement of certain events, modification of event formats, and cancellation or replacement of some activities with religious and cultural observances to honor Her Majesty’s legacy with utmost respect.

Revised Event Schedule and Format

Vijit Chao Phraya Thailand 2025

Originally scheduled from 1 November – 15 December 2025, the event will now be held from 9 November – 23 December 2025 along both sides of the Chao Phraya River in Bangkok.
The event concept has been revised under the theme “The Light of Siam: Mother of the Land” to commemorate Her Majesty’s boundless royal grace. Fireworks displays will be replaced by a drone light show, symbolizing national mourning and reverence. The lighting tone and color scheme will also be adjusted to reflect solemnity and respect.
On New Year’s Eve, TAT invites the public to join a commemorative activity titled “Candlelight of the Land”, where candles will be lit nationwide as a tribute to Her Majesty.

Scheduled for 2–6 November 2025 at Wat Phra Ram, within the Ayutthaya Historical Park, this event will proceed as planned but with modifications in tone and presentation to reflect the national mourning period.
