Every year, Thailand’s waterways and skies are rewritten in gold and ember: candles glow on tiny banana-leaf rafts, incense curls into humid air and, in the north, thousands of paper lanterns lift like a slow, breathing constellation. Loy Krathong— and its sister northern celebration Yi Peng— are at once intimate personal rites and dazzling public theatre. For 2025, the main water-launch night is tied to the full moon and falls on November 6, with Chiang Mai’s Yi Peng lantern events staged across the nights around it.
Loy Krathong (literally “float a krathong”) traces its name to the Thai words loy (“to float”) and krathong (a small offering or raft). The ritual has layered origins: Buddhist and older Hindu river-worship practices were adapted over centuries into the gentle, symbolic act of releasing a candleed krathong to thank the water goddess and “let go” of misfortune. Traditional krathongs were made from banana stalks and folded banana leaves; modern versions have varied, and environmental concerns around non-biodegradable materials have pushed communities to favour biodegradable or bread-based options.
Loy Krathong appears across Thailand, but four places stand out:
• Chiang Mai — The north stages the spectacular Yi Peng lantern releases (sky lanterns or khom loi) alongside river krathong ceremonies. Organised ticketed events and mass releases draw huge crowds on the nights around November 5–6 in 2025. If you want the iconic lantern photograph, Chiang Mai is the place, but expect crowds and buy tickets or join a tour.
• Sukhothai — Often cited as the festival’s spiritual home, Sukhothai’s historical park creates a haunting tableau: temple ruins, ponds and hundreds of candlelit krathongs on reflective waters. It’s quieter and more 'authentic' than big-city scenes.
• Bangkok (Chao Phraya & Lumphini Park) — Bangkok’s riverfront and large parks host public events and floating ceremonies; luxury riverside hotels and Asiatique run special dinners and boat cruises for close-up views. Plan for heavy traffic and book river cruises early.
• Ayutthaya & other river towns — Ancient Ayutthaya and places such as Kanchanaburi or provincial river towns combine local pageantry with temple rituals and are good options if you want atmosphere without mega-crowds.
• Make or buy a krathong — Traditional krathongs are crafted from banana trunk slices, folded banana leaves, flowers, a candle and incense sticks. Choose biodegradable options— many temples and vendors sell eco-friendly krathongs. Avoid Styrofoam and plastics; some places ban them.
• Join a lantern release responsibly — In Chiang Mai, organised Yi Peng events sell tickets and coordinate mass releases to minimise fire risk and environmental damage. Do not release sky lanterns in crowded urban areas, near airports, or over fields; follow local organisers’ instructions.
• Temple etiquette — Dress modestly, remove shoes when required, and be quiet and respectful during merit-making. If you place hair or nail clippings into a krathong as a symbolic “letting go,” use the offerings receptacles at temples rather than throwing hazardous items into waterways.
• Photography & crowds — Expect large crowds at main sites; tripod rules, cordoned viewing areas, and ticketed platforms are common. For more intimate photos, arrive early to riverside parks or opt for smaller provincial towns.
When: Loy Krathong 2025 is centred on the full moon night of November 6; Yi Peng events in Chiang Mai take place on the nights around November 5–6. Book travel and accommodation at least 2–3 months ahead for Chiang Mai and Bangkok.
Getting there: Bangkok and Chiang Mai are major air hubs with international connections. From Bangkok, domestic flights to Chiang Mai and Sukhothai sell out fast during festival season; trains and overnight buses are alternatives but must be booked early. For Sukhothai and Ayutthaya, consider renting a car or hiring a driver for flexible timing.
Money & bookings: Expect surge pricing for hotels and special event tickets. Buy Yi Peng or lantern-release tickets only from reputable vendors (official event pages, major tour platforms or accredited hotels). Beware unofficial mass-release gatherings that may lack safety oversight.
Safety & environment: Watch for open flames, keep a safe distance from fireworks and lanterns, and never leave candles unattended. Dispose of krathongs responsibly— many communities collect them the morning after for eco-processing; follow local instructions.
1. When is Loy Krathong and Yi Peng in 2025?

Yes — but only at organised and permitted events. In Chiang Mai, official venues manage lantern releases safely to prevent fires and air traffic risks. Independent or unsanctioned releases are discouraged or banned in urban areas.
