Few images are as closely associated with Thailand as thousands of glowing lanterns rising into the night sky. For many travellers, this magical scene is their first introduction to Yi Peng, one of Northern Thailand’s most distinctive and visually spectacular festivals.
Often confused with Loy Krathong, Yi Peng is a separate celebration with its own history, traditions and cultural significance. While the two festivals usually take place around the same time and are often experienced together in Chiang Mai, understanding the differences between them allows visitors to gain a deeper appreciation of Northern Thailand’s unique heritage.
Yi Peng is rooted in the traditions of the former Lanna Kingdom and remains particularly important in Northern Thailand. Beyond the stunning lantern displays, the festival is a time of reflection, merit-making and community celebration.
For travellers planning a visit to Thailand, experiencing Yi Peng can be one of the most memorable cultural events of any journey through Southeast Asia.
What Is Yi Peng?
Yi Peng is a traditional Northern Thai festival celebrated primarily in Chiang Mai and other parts of the former Lanna Kingdom.
The name “Yi Peng” comes from the ancient Lanna calendar:
- “Yi” means two.
- “Peng” refers to the full moon day.
The festival takes place during the second full moon month of the Lanna calendar, which typically coincides with November.
Unlike Loy Krathong, which focuses on floating decorative offerings on water, Yi Peng is known for the release of khom loi—paper lanterns that are lifted into the sky by heated air.
As lanterns ascend into the darkness, they create one of the most remarkable festival scenes in the world.
The History of Yi Peng
Yi Peng has deep roots in the cultural traditions of Northern Thailand.
The festival originated within the Lanna Kingdom, which ruled much of what is now Northern Thailand between the thirteenth and eighteenth centuries.
Many aspects of Lanna culture continue to influence Chiang Mai and the surrounding region today, including:
- Architecture
- Food
- Language
- Religious traditions
- Festivals
Historically, lanterns were used during religious ceremonies as symbolic offerings and expressions of devotion.
Over time, the tradition evolved into the large-scale celebrations seen today while maintaining its spiritual significance.
Understanding this historical context helps travellers appreciate Yi Peng as more than simply a photogenic event.
The Meaning Behind the Lanterns
One reason Yi Peng resonates with so many people is the symbolism attached to the lantern release.
For many participants, releasing a lantern represents:
- Letting go of negativity
- Releasing worries or misfortune
- Making wishes for the future
- Seeking good fortune
- Reflecting on personal growth
The act of watching a lantern drift into the sky can be deeply meaningful, even for visitors who do not share the religious traditions associated with the festival.
Many people view the experience as an opportunity for reflection and renewal.
This deeper significance helps explain why Yi Peng remains an important cultural celebration rather than simply a tourist attraction.
How Yi Peng Is Celebrated
Although lantern releases are the most internationally recognised aspect of the festival, Yi Peng includes many other activities.
Temple Visits
Many local residents visit temples to make merit and participate in religious ceremonies.
Lantern Decorations
Homes, businesses and public spaces are often decorated with colourful lanterns.
Community Gatherings
Cultural performances, traditional music and local events take place throughout the festival period.
Merit-Making Activities
Acts of generosity and community support remain an important part of the celebration.
Lantern Releases
The release of sky lanterns remains the festival’s most iconic tradition.
Together, these activities create a vibrant atmosphere that extends beyond a single evening.
Chiang Mai: The Heart of Yi Peng
While Yi Peng is celebrated throughout parts of Northern Thailand, Chiang Mai is widely regarded as the festival’s centre.
Several factors contribute to the city’s reputation:
- Strong Lanna cultural heritage
- Historic temples
- Large-scale community celebrations
- International recognition
- Beautiful festival settings
During Yi Peng, Chiang Mai’s streets, temples and waterways come alive with activity.
Travellers often find that the entire city feels transformed by the festival atmosphere. If you’d like to experience Chiang Mai beyond its famous festivals, our Experience Northern Thailand tour explores the region’s temples, mountain landscapes and rich Lanna heritage.
This is one reason why accommodation and tours should be booked well in advance, as demand is particularly high during festival periods.
Yi Peng and Loy Krathong: Understanding the Difference
Many visitors assume Yi Peng and Loy Krathong are the same festival.
While they often occur on the same dates, they have different origins and traditions.
Yi Peng
- Northern Thai festival
- Associated with the Lanna Kingdom
- Focuses on sky lanterns
- Celebrated mainly in Northern Thailand
Loy Krathong
- Celebrated nationwide

In Chiang Mai, the two festivals overlap, allowing visitors to experience both traditions during a single trip.
Understanding this distinction can help travellers better appreciate the cultural richness of the celebrations.

In recent years, growing visitor numbers have highlighted the importance of responsible festival participation.
Travellers can contribute positively by:
