Bangkok's riverfront is about to get seriously glowy. Vijit Chao Phraya 2026, the Tourism Authority of Thailand's fifth annual light festival, runs from 13 November to 13 December this year, spreading 19 illuminated installations along the Chao Phraya between Rama VIII Bridge and Rama III Bridge — plus a floating barge of light drifting down the river.

This year's theme, "The Light of Imagination", leans on light art, projection mapping, lasers, drones and fireworks to reinterpret the river's history and communities. A new twist for the fifth edition: collaborations with Chulalongkorn University, Thammasat University and King Mongkut's Institute of Technology Ladkrabang, whose students are behind several installations.

The schedule has some genuine standouts. Wat Arun gets an 800-drone light show at 19.50 on ten selected evenings across the month. Rama VIII Bridge hosts nightly laser symphonies (six shows a night, every half hour from 19.00) plus waterfall-style fireworks on selected dates. Memorial Bridge becomes "Hanuman Awakening the River of Light", ICONSIAM runs its multimedia water-feature spectacle six times nightly, and even the Bank of Thailand Museum, Siriraj's historic clock tower, a Presbyterian church and The Langham hotel get their own projection shows. Fireworks also fire off at Rama III and Memorial Bridges on various November and December evenings.

The floating piece, "Vessel of Joy & Smiles", is an illuminated barge with Light On Balloon technology travelling between the Sathorn area and Rama III Bridge from 13–15 November, 18.00–22.00 each evening.

Everything is free, running 18.00–22.00 daily. TAT frames the festival as part of its night-economy push — the idea being that a month of evening spectacle spreads money to cruises, hotels, restaurants and riverside communities on both banks during Thailand's high season. For travellers, that means plenty of dinner-cruise options and lively piers, but also bigger crowds around the headline sites.

Practical tip: you can't see all 19 locations in one night, so pick a cluster. The Wat Arun, Wat Kalayanamit and Wichai Prasit Fort area works well on a drone-show evening, while Rama VIII Bridge and ICONSIAM make an easy pairing on the opposite side of the river. Local boats and licensed cruise operators are the way to hop between spots. Show times vary by venue and date, so check the festival's Facebook page or thailandfestival.org before heading out.

If you're in Bangkok between mid-November and mid-December — a great time weather-wise anyway — this is one of the city's most atmospheric free events, and it pairs neatly with the cooler-season festival mood building towards the holidays. Details via Laotian Times.
