Come December, the blazing colors of Chichicastenango market reach their zenith. Villagers from the highlands pour into town, all in distinct traditional dress.
Clouds of incense and deafening bangers accompany a parade in honor of the patron saint, and plenty of drinking, dancing, and falling over is enjoyed by all.
The most famous festival in Chichi is the Fiesta de Santo Tomás, in honor of the town’s patron saint. The Fiesta occurs in mid-December every year, and lasts a full week. It is organized by a cofradía, or honorable fraternity of town elders. The parade of the cofradía through the town toward the church, accompanied by flute and drum music, marks the beginning and end of the festival. Source
