There is a night in November when Thailand glows. On the rivers, thousands of small candlelit baskets drift downstream, and in the north, the sky itself fills with thousands of rising paper lanterns, a slow upward snowfall of light. This is Loy Krathong, and its northern cousin Yi Peng, Thailand's most beautiful festival, a nationwide act of letting go, gratitude, and wishing that turns water and sky into rivers of flame.
Loy Krathong: setting light on the water
Loy Krathong means, roughly, to float a basket. On the full moon of the twelfth lunar month, Thais make or buy a krathong, a small float traditionally crafted from a banana-tree trunk and leaves, decorated with flowers, a candle, and incense. At nightfall they carry it to a river, canal, or lake, light the candle, make a wish, and gently set it adrift on the water.
The meaning is layered and lovely. The float is an offering of thanks and respect to the water, to the goddess of rivers, for the water that sustains life. And it is an act of letting go, releasing the misfortunes, grudges, and bad luck of the past year, watching them drift away on the current as you wish for better. To stand on a riverbank as thousands of tiny flames float past in the dark is quietly magical.
You place your bad luck and your wishes on a little raft of light, and you let the river carry them away. That is Loy Krathong, and it is as moving as it sounds.

Yi Peng: setting light in the sky
In the north, around Chiang Mai, Loy Krathong coincides with the Lanna festival of Yi Peng, and this is where the most iconic images come from. Instead of, or alongside, floating krathong on the water, people release khom loi, paper sky lanterns, into the air. Heated by a small flame, the lanterns rise gently and drift upward in their thousands, until the entire night sky is filled with floating points of golden light, a sight so beautiful it has become one of the most photographed festivals on earth.
The mass releases, when thousands of lanterns ascend together, are genuinely breathtaking, a slow, silent storm of light rising into the dark. As with the krathong, the rising lantern carries away your troubles and your wishes, a release in the most literal sense. Chiang Mai at Yi Peng is one of those places that looks too beautiful to be real, and then is.
How to experience it well
- Chiang Mai for the sky lanterns, riverside towns and Bangkok for the floating krathong. The two traditions overlap but the north is the place for the iconic mass lantern release.
- Book very early. This is one of Thailand's most popular festivals and Chiang Mai fills completely. Plan months ahead.
- Choose eco-friendly krathong. Floats made of bread or natural materials, rather than foam, reduce the pollution that thousands of krathong can cause.
- Mind the lantern rules. Sky lantern releases are regulated for flight safety and fire risk, so join organised, permitted events rather than launching at random.
- Make a wish and let go. Engage with the meaning, not just the photograph. The whole point is release and gratitude.
A festival about release
What gives Loy Krathong and Yi Peng their depth is the idea at their heart: that you can set down what weighs on you. The float on the water, the lantern in the sky, both carry away the past year's misfortunes and lift your hopes into the dark. It is a festival of beauty, yes, perhaps the most beautiful in Asia, but also of a gentle, universal wisdom about gratitude and letting go. You leave it lighter, in every sense.
Thailand's most beautiful night is also its wisest: float your troubles down the river, send your wishes into the sky, and walk home a little lighter.
On the OJ Thailand trip the warmth, beauty, and spirit of the country are the heart of the journey, the festivals, the temples, the river towns, the easy welcome that makes Thailand the most-loved gateway to Asia. Because the sky full of lanterns is the spectacle, but a country that marks the year by floating its troubles away on rivers of light tells you exactly why travellers keep losing their hearts to Thailand.
Frequently asked
When is Loy Krathong celebrated?
Loy Krathong falls on the full moon of the twelfth month in the Thai lunar calendar, usually in November. In northern Thailand, around Chiang Mai, it coincides with the Lanna festival of Yi Peng, famous for its sky lanterns. The exact dates shift each year with the lunar calendar, so confirm before planning a trip.
What is the difference between Loy Krathong and Yi Peng?
Loy Krathong is the nationwide tradition of floating decorated candlelit baskets, krathong, on rivers and lakes as an offering and an act of letting go. Yi Peng is the northern Lanna festival, centred on Chiang Mai, of releasing thousands of paper sky lanterns, khom loi, into the night air. They overlap, and Chiang Mai is the place for the iconic sky lanterns.
What do Loy Krathong and Yi Peng symbolize?
Both are acts of gratitude and letting go. Floating a krathong thanks the water and the river goddess and releases the misfortunes and grudges of the past year, while making a wish. Releasing a sky lantern similarly carries away troubles and lifts hopes into the sky. The festival is about renewal, release, and gratitude as much as beauty.
