Be aware of pickpockets everywhere in Guatemala, especially at the market in Chichicastenango!!! Is very crowed and my friends mobile phone was nicked here.
When you are working your way through the crowds at the ChiChi market you are very vulnerable to pickpockets and other thieves.We always wear our daypacks and camera cases to the front of us. I have seen thieves come up behind someone with a pack on their back and the thief has lifted an item without the owner knowing what has happened. The walkways between booths and vendors is very narrow and caution is necessary.
Don't go to the cemetery on the town's west side even in groups. There have been several reports of tourists being robbed at gunpoint. Don't go to deserted area either.
