Loy Krathong is one of Thailand's most poetic festivals. On the full moon of the twelfth lunar month — usually November — thousands of people gather at bodies of water to release a krathong, a small floating offering made from banana leaves or bread, decorated with a flower, a candle and incense sticks. It is believed that the krathong carries away past grievances, anxieties and misfortunes.

Origins and Meaning

The precise origin of Loy Krathong remains a matter of scholarly debate: some historians trace it to an ancient Brahmin ritual honouring the water goddess Phra Mae Khongkha, others to a Buddhist custom of venerating the Buddha's footprint by the river Nammatha. Whatever its roots, the festival has endured and become a central part of Thai secular culture.

On Koh Samui, surrounded by sea, krathongs are released directly into the Gulf. This changes the atmosphere: there is no narrow riverbank to contain the moment — thousands of little lights spread across the dark water in every direction. At the same time the sky above the beach glows with khom loi sky lanterns — paper spheres with an open flame that drift slowly upward.

Where to Celebrate on Koh Samui

Chaweng Beach — the most crowded venue. Market stalls, live music, and ready-made krathongs and khom loi for sale. The atmosphere is carnival-like; hundreds of lanterns fill the sky simultaneously.

Lamai Beach and Bo Phut waterfront — quieter options. Fisherman's Village in Bo Phut is especially beautiful on this evening: wooden buildings along the pier reflect in the water among the floating lights.

Waterside shrines and temples — many Thai residents prefer to release krathongs at Buddhist temples beside the water. The ceremony here is more meditative and less touristy.

How to Make a Krathong

Ready-made krathongs are sold at markets and on the beach for 30–150 THB. A traditional krathong is crafted from banana leaves rolled into a rosette shape and decorated with fresh flowers and a candle. Eco-friendly versions made from bread or rice wafer decompose in the water without harming the marine environment — these are the ones recommended by the island's authorities.

Practical Tips

  • Arrive at sunset — the most beautiful atmosphere develops in the first one to two hours after dark.
  • Consider dressing in Thai style: many visitors rent traditional costumes and this is warmly received by local residents.
  • Make a wish before releasing your krathong — that is the custom.
  • Use khom loi lanterns with care: launch only in designated areas, well away from trees and buildings.
  • November marks the beginning of high season; beaches will be busy. Arrive early for a better vantage point.

Loy Krathong on Koh Samui is a rare occasion when visitors and local residents share the same celebration side by side, united by a common feeling: something important is being released, and something new is about to begin.
