Loi Krathong — Festival of Lights (November)

Loi Krathong is Thailand's festival of lights, celebrated on the full moon night of the 12th lunar month — usually mid-November (the date shifts each year; recent dates: Nov 27 2023, Nov 15 2024, Nov 5 2025, Nov 24 2026). The defining ritual: floating a small candlelit raft (krathong) made from banana leaves, flowers, candles, and incense onto a body of water, in a gesture of letting go of bad luck and offering thanks to the river goddess.

The shape of the festival: - Daytime: crafting krathongs (sold at markets — 50–200 baht each, biodegradable banana-leaf versions preferred), lantern decorations along temples and major rivers. - Evening: crowds gather along the Chao Phraya River, Lumphini Park lake, hotel pools, and any visible water. Krathongs are floated. Music, food stalls. - Yi Peng (the parallel northern Thai festival, celebrated mainly in Chiang Mai): thousands of paper sky lanterns released into the night sky. Photo-iconic. Bangkok also has small lantern releases at certain temples but the Chiang Mai Yi Peng experience is the famous one (book Chiang Mai 6+ months ahead if that's your goal).

For travelers in Bangkok:

Best places to float a krathong: - Chao Phraya River at Asiatique pier, Tha Maharaj, ICONSIAM riverside, or any of the Chao Phraya Express piers — large, photogenic, busy. - Lumphini Park lake — central, less crowded than the river, walking distance from Silom hotels. - Hotel rooftop pools (sometimes hotels run organized krathong-floating events for guests). - Wat Saket / Golden Mount — small but atmospheric, with sky lantern releases.

Practical: - Crowds are huge. Plan to be at the river pier 30–60 min before sunset to find a spot. - Hotels surge prices — typically +20–40% over the festival night. Book early. - Restaurants near major krathong sites get packed — reserve dinner if you have a target restaurant. - The weather is perfect. November is one of the best months in Bangkok — dry, low humidity, 25–32°C.

Yi Peng (Chiang Mai sky lanterns): - The mass-release events happen 1–2 days around Loi Krathong, sometimes earlier. - The Yee Peng Sansai event at Mae Jo (north of Chiang Mai) is the famous tens-of-thousands lanterns release — paid ticket only, books out months ahead. - Smaller free releases happen along Chiang Mai's old city moat and temples. - Sky lantern releases are restricted in many parts of Thailand for aviation safety. Bangkok has limited zones; Chiang Mai is the iconic place.

Cultural notes: - It's a romantic / family festival, not a party festival. Water-fight festivities are NOT involved (that's Songkran). - The krathong is biodegradable — banana-leaf versions break down in days. Avoid styrofoam versions (still sold but officially discouraged). - "Loi" = "to float", "Krathong" = "the small raft". Pronounced loh-ee kruh-tong (roughly).

When the agent should reference this: any November trip plan, any romantic-couple trip in Q4, photography-focused trips, anyone considering a Chiang Mai side-trip with timing flexibility (Yi Peng is the photo of a lifetime). For Bangkok specifically, recommend the Chao Phraya River viewing as the canonical experience.
