The image of thousands of glowing lanterns rising into the night sky over Chiang Mai is one of the most magical sights in Thailand — and it's real, happening each year during the Yi Peng festival. Combined with the simultaneous Loy Krathong, when candle-lit floats drift down the rivers, it's a bucket-list experience. Here's what these festivals are and how to experience them well.
What are Yi Peng and Loy Krathong?
Two related festivals fall at the same time. Loy Krathong is celebrated across Thailand: people float small decorated baskets (krathong) bearing candles and incense on rivers and lakes, symbolically letting go of misfortune and giving thanks to the water goddess. Yi Peng is a northern Lanna tradition centered on Chiang Mai, famous for releasing khom loi — paper sky lanterns — into the air. Together they fill Chiang Mai's rivers with lights and its sky with lanterns, creating an unforgettable spectacle.
When does it happen?
The festivals follow the lunar calendar, falling on the full moon of the twelfth lunar month — usually in November, with the exact dates changing each year. Because dates shift annually, check the specific year's dates well in advance if you want to plan a trip around them. The festivities span several days around the full moon, with the main lantern nights being the highlight.
How to experience the lanterns
There are a few ways to see the sky lanterns. Around the city, especially near the old city, rivers, and bridges, people release lanterns and float krathong — atmospheric and free, though crowded. Ticketed mass-release events outside the city stage the iconic synchronized release of thousands of lanterns at once (the postcard image); these sell out far ahead and can be pricey. Both offer something different — the organized events for the spectacle, the city for the authentic local atmosphere.
Book everything early
This is essential: the festival is hugely popular, and Chiang Mai books out months in advance. Accommodation prices spike and the best places fill early, flights get expensive, and ticketed lantern events sell out well ahead. If you want to experience Yi Peng, plan and book your accommodation, flights, and any event tickets as early as you can — this is not a trip to leave to the last minute.
What else happens during the festival
The lanterns are the headline, but the festivals bring much more. Expect parades and processions, beautifully decorated krathong-making, temple ceremonies, fireworks, markets, and the whole old city dressed in lights and lanterns. The bridges over the Ping River become gathering points for floating krathong, and the temples host special observances. Even without a ticket to a mass lantern release, simply being in Chiang Mai during the festival — wandering the lantern-strewn streets, joining locals floating krathong on the river — is a magical experience in itself, and arguably the more authentic side of the celebration.
Doing it respectfully and responsibly
A few important notes. These are spiritual and cultural traditions, not just a photo op — observe respectfully, especially at temples. There are environmental concerns around sky-lantern and krathong waste, so use biodegradable krathong where possible and follow local rules on lantern releases (which are restricted in some areas and times, including near the airport for safety). Be mindful of fire safety with lanterns. Engaging thoughtfully makes the experience richer and kinder to the place hosting it.
Is it worth planning a trip around?
If experiencing the lanterns is a dream of yours, yes — it's genuinely magical and a highlight of many travelers' lives. Just go in with realistic expectations about crowds and costs, book very early, and approach it as a cultural experience rather than just a spectacle. It also happens to coincide with the lovely cool season, making November a beautiful (if busy and pricey) time to be in the north. For budgeting the festival premium, a live converter helps:
