A krathong is a traditional Thai floating lantern made from natural materials like banana leaves, flowers, and candles. It is often shaped like a small boat and is used during the Loy Krathong festival, which celebrates the end of the rainy season. People create and release krathongs onto rivers and lakes as a way to pay respect to the water spirits and seek forgiveness for past misdeeds. During the Loy Krathong festival, which usually occurs in November, thousands of krathongs are released into the water, creating a beautiful sight. The act symbolizes letting go of negativity and making wishes for the future. This custom is an important part of Thai culture and attracts both locals and tourists.
