Everything you need to know about Northern Thailand's lantern festival — dates, etiquette, and where locals actually go.
The photograph you have seen — a thousand lanterns lifting off a dark field in perfect unison — is real, and it is almost certainly not what you will get by turning up in Chiang Mai during Yi Peng.
Understanding why is the difference between a disappointing week and a very good one.
What Yi Peng actually is
Yi Peng is the Lanna festival of lights, held on the full moon of the second Lanna month. For 2026 the main dates fall on 24–25 November, with Loy Krathong on the same full moon — which is why the two are marketed as one event and why most visitors leave thinking they are.
Releasing a khom loi, a sky lantern, symbolises letting go of misfortune. The images of a thousand lanterns rising at once come from this night.
That part is true. The part about being able to do it wherever you like is not.
The famous mass releases are mostly ticketed events outside the city. In Chiang Mai itself the celebration is scattered and, many would argue, more genuine — lanterns going up from riversides, temple courtyards strung with lights, krathong floating down the Ping. No stage. No queue.
The lantern reality
Sky lanterns are not released freely across Chiang Mai, and this is the single most misunderstood thing about the festival.
The city sits under active flight paths. Provincial authorities issue an order every year restricting release to specific times and licensed zones, with a flight-safety corridor of roughly 15 km around Chiang Mai Airport off-limits entirely. Districts including Hang Dong, Saraphi, San Sai, Mae Rim, San Patong and Mueang Chiang Mai have been designated red zones in past years. The permitted windows are usually announced only a few weeks in advance.
Releasing outside those windows is an offence. Reported penalties vary a great deal depending on which law is applied — figures in circulation range from tens of thousands to two hundred thousand baht in fines, with imprisonment terms attached. We are not going to give you a single number, because the sources do not agree and because the point stands either way: this is not a fine you shrug at.
Flights in and out of Chiang Mai are routinely rescheduled around the festival and the last scheduled departure has been moved earlier in past years. If you have a tight connection on those dates, do not assume it holds.
The ticketed releases
The synchronised mass releases in the famous images are private ticketed events held outside the city, most prominently in the Mae Jo area. They sell out months ahead, tickets are not sold at the gate, and prices run to several thousand baht per person depending on the package.
If that specific photograph is the whole point of your trip, it needs booking before you book anything else, including flights.
If it is not — and for most people it should not be — skip it. What you get for the money is twenty minutes of a very good photograph in a field with two thousand other people who are also taking it.
Where locals go
Spend the evening around Nawarat Bridge and the Ping riverbank, where families release krathong without any of the tourist pricing. Or in the old city temples — Wat Phan Tao's lantern-lit courtyard is the most atmospheric place in Chiang Mai on those nights and it costs nothing.
Tha Phae Road carries the parades. Worth catching for the Lanna costume and the floats, even if you have no interest in lanterns at all.
What else is happening that week
The lanterns get the attention, but the festival around them runs for several nights. Houses and temples across the north hang lantern lights and build decorated gateway arches, and the temple fairs go on well past the headline dates.
The old city temples light their courtyards for multiple evenings, so a night when the crowds are thinner still gets you the atmosphere. This is the practical advice nobody gives: come for the shoulder nights, not the peak one.
The Ping riverbank is the quiet half of the festival. Families arrive at dusk with krathong, and the water side of the week has none of the ticketing, scheduling or queueing that the sky side does. If you are in Chiang Mai in the old city during the day, the temple-district cafes are the right place to wait out the afternoon heat before any of it starts.

Dates follow the lunar calendar and are confirmed by the province only a few months out — do not book flights against a guessed date. Lantern restrictions and penalties are reissued annually and reported inconsistently; check the current year's provincial order before planning anything around a release. Use a banana-trunk or bread krathong, not foam, which many areas ban outright. Checked September 2026.
