Every year, around the full moon of the 12th month of the Thai lunar calendar, people across Thailand gather beside rivers, canals, lakes, and ponds to celebrate Loy Krathong. They place small, decorated floats called krathongs on the water as a gesture of gratitude, reflection, and good wishes.
Often called Thailand's Festival of Lights, Loy Krathong is known for its candlelit floats and festive evening atmosphere. The celebration usually takes place in November, although the exact date changes each year.
Loy Krathong is often associated with Yi Peng, the northern Thai lantern festival, but the two have different traditions. Understanding the difference helps visitors appreciate the cultural meaning behind the celebrations.

What Is Loy Krathong?
The name Loy Krathong combines two Thai words. Loy means "to float," while a krathong is a small floating vessel traditionally made from banana leaves or sections of a banana trunk.
Krathongs are usually decorated with flowers, a candle, and incense sticks. After dark, people light their offerings and gently set them afloat at designated waterways.
The sight of hundreds of candlelit krathongs drifting across the water is one of the festival's most memorable features. For many Thai people, however, the tradition carries a meaning beyond its beautiful appearance.
What Does Loy Krathong Mean?
Loy Krathong is associated with gratitude, reflection, and the hope for a fresh start.
Giving thanks to water. Many people use the occasion to express gratitude for water and ask forgiveness from Phra Mae Khongkha, the goddess of water, for its use and pollution.
Letting go of negativity. Floating a krathong can symbolize leaving behind bad luck, worries, regrets, or difficulties from the past year.
Making wishes for the future. Some people make a wish or say a quiet prayer as their krathong drifts away, hoping for happiness, good fortune, and new beginnings.
The festival's historical origins are not fully settled. A popular legend connects Loy Krathong with Nang Noppamas, a court lady associated with the ancient kingdom of Sukhothai, but this story should be understood as a traditional legend rather than a confirmed historical account.

Traditional Loy Krathong Activities
Making a Krathong
Creating a krathong is part of the festival experience. Traditional designs often use folded banana leaves, flowers, and other natural materials. Some communities also organize workshops where visitors can learn how to make their own floats.
If you plan to participate, choose a biodegradable krathong and follow local guidance on where and how to release it.
Floating Krathongs on the Water
After sunset, families, couples, and friends gather near designated waterways to float their krathongs. Many take a moment to reflect on the past year or make a wish before setting their offerings on the water.
Visitors can often join these activities at public celebrations, provided they follow local instructions and respect the customs of the community.
Enjoying Local Festivities
Depending on the destination, Loy Krathong celebrations may include traditional music and dance, cultural performances, parades, local markets, and Thai street food.
The scale and program vary by location and year. Some events focus on traditional ceremonies, while others combine cultural activities with larger public celebrations.
Loy Krathong vs. Yi Peng: What's the Difference?
Although the two festivals often take place around the same time, Loy Krathong and Yi Peng are distinct traditions.
| Feature | Loy Krathong | Yi Peng |
|---|
| Main tradition | Floating decorated krathongs on water | Lighting and displaying sky lanterns |
| Cultural roots | Celebrated throughout Thailand | Rooted in Lanna culture in northern Thailand |
| Best-known setting | Rivers, canals, lakes, and ponds | Chiang Mai and other northern Thai communities |
| Common symbolism | Gratitude, reflection, and good wishes | Spiritual devotion, good fortune, and letting go of misfortune |
Chiang Mai is especially well known because visitors can experience Loy Krathong celebrations alongside Yi Peng traditions. However, sky lantern releases are subject to local rules and air-safety restrictions. They should only take place at authorized events or locations where they are permitted.

How to Celebrate Loy Krathong Respectfully
Visitors are welcome at many public celebrations, and a few simple considerations can help make the experience more meaningful.
Choose eco-friendly materials. Avoid krathongs made from plastic or Styrofoam. Follow local advice on acceptable materials.
Use designated release areas. Do not enter waterways or release floats where local authorities prohibit the activity.
Follow lantern and firework restrictions. Never assume that sky lanterns or fireworks are permitted simply because a festival is taking place.
Respect local customs. Observe how residents participate, dress appropriately when visiting temples, and follow event instructions.
Plan around crowds. Popular riverside areas can become busy after dark. Allow extra time for transport and check local arrangements before heading out.
When Is Loy Krathong Celebrated?
Loy Krathong takes place on the full moon of the 12th month of the traditional Thai lunar calendar, usually in November. Its Gregorian calendar date changes every year.
If you are planning a trip around the festival, check the dates and event schedules for your chosen destination before booking flights or accommodation. Some celebrations last several days, while the main activities may take place on a particular evening.
