The market at Chichicastenango is open on Thursdays and Sundays and is one of the most enriching cultural experiences you can have. This indigenous town is also where the scared, 400-year old St. Thomas Church is located. On these days it’s easy to find Mayan priests performing rituals, lighting incense, and praying, with flower vendors layer out on the stairs of the church selling flowers.
It's important to be incredibly respectful of the people in prayer, the rituals, and most of all the sacred areas. Traveling with a guide helps you navigate through the country and understand these nuances and details.
