Every November, when the full moon rises over Thailand, the country transforms into a glowing wonderland. Rivers sparkle with candlelit floats and the northern skies shimmer with lanterns lifting into the night. These are the magical twin festivals of Loy Krathong and Yee Peng, celebrations that capture the soul of Thailand—gratitude, renewal, and the eternal dance of light over darkness.
A Story Rooted in Tradition
The story of Loy Krathong is woven from many threads. Some trace it back to ancient Brahmin rituals in India, where floating lamps were released to honor river deities. In Thailand, the practice merged with Buddhist traditions, becoming an act of offering light to the Buddha while symbolically letting go of sorrow, misfortune, and mistakes. Folklore tells us that Nang Noppamas, a lady-in-waiting in the royal court of Sukhothai, first crafted a krathong to delight her king. Whether or not the story is true, it lives on in the beauty of the floating offerings we see today.
In the north, the ancient Lanna kingdom developed its own luminous ritual. Known as Yee Peng, it is celebrated in harmony with Loy Krathong and tied to the Lanna lunar calendar. Here, instead of floating lanterns on water alone, people send glowing lanterns into the night sky, creating a breathtaking connection between the earthly and the spiritual.
Following the Moon
Both festivals are guided by the lunar cycle. Loy Krathong always takes place on the night of the full moon in the twelfth lunar month, usually in November. In the Lanna tradition, Yee Peng aligns with the full moon of the second month of their own calendar, which often coincides with Loy Krathong. In 2025, the celebrations fall around November 5–6, marking the end of the rainy season and the beginning of a new cycle of renewal.
Rituals of Light and Letting Go
To take part in Loy Krathong, people craft small, delicate floats from banana leaves, flowers, and slices of banana tree trunk. A candle and incense sticks crown each krathong, and some families add nail clippings or a lock of hair to symbolize the release of personal misfortunes. Once lit, the krathong is gently placed into a river or pond, carrying away regrets and carrying forward hopes.
Yee Peng, meanwhile, fills the air with light. Lanna-style lanterns are made from rice paper stretched over bamboo, lifted by the heat of a small flame. As they ascend into the night, wishes are carried skyward. Around temples, the glow multiplies: lanterns hung in trees, thousands of candles lit along walkways, processions of light illuminating the night.
Yet it is important to know that in many urban centers, including Chiang Mai city, the release of sky lanterns is now prohibited for safety reasons. Fire hazards and risks to air traffic have made authorities limit or ban lantern launches. If you dream of experiencing the true Yee Peng lantern spectacle, Lamphun and other nearby areas still host organized and safe events.
Where to Witness the Magic
Loy Krathong is celebrated across Thailand, but some places offer truly unforgettable experiences. In Bangkok, the Chao Phraya River becomes a stage of lights, with glittering temples and thousands of krathongs floating past. Ayutthaya and Sukhothai bring a sense of history to the celebration, their ancient ruins reflecting the glow of candles and floats.
Chiang Mai’s streets and temples burst with decoration, though the true lantern releases are now found in surrounding towns. Lamphun, just south of Chiang Mai, has become the heart of the Yee Peng Lanna Festival, offering a more intimate northern-style celebration where both krathongs and lanterns create a luminous harmony of water and sky.
Insider Tip : Today, many Thais emphasize using eco-friendly krathongs made from natural or biodegradable materials, avoiding plastic or Styrofoam altogether. Visitors are encouraged to honor these traditions with the same care.
