Every year, Thailand’s waterways and skies are rewritten in gold and ember: candles glow on tiny banana-leaf rafts, incense curls into humid air and, in the north, thousands of paper lanterns lift like a slow, breathing constellation. Loy Krathong— and its sister northern celebration Yi Peng— are at once intimate personal rites and dazzling public theatre. For 2025, the main water-launch night is tied to the full moon and falls on November 6, with Chiang Mai’s Yi Peng lantern events staged across the nights around it.
