Each week there's an explosion of colors, fabrics and carried and put together by the Mayan women that come from all over Guatemala to sell their goods in the tiny town of Chichicastenango. This little villages stays very quiet 5 days a week but on Sunday and Thursday locals and foreigners come to get lost in the Central America's largest market. We ended up spending 3 hours in town. There are a few must visit spots in the area including the town's main church (Iglesia de Santo Tomas), of course the market itself (which is in front of the church), and lastly the very colorful cemetery located 5 minutes from the market.
If you're staying at Lake Atitlan, Antigua, or Xela it's an easy day trip and can be done via chicken bus or tour shuttles.
The weekend markets here may be derided as touristy, but they're also a fun and accessible spot full of local colour. Hone your bargaining skills while you wander the lanes checking out carved wooden masks, colourful textiles, and everything else under the sun.
