It is not safe to drink the tap water in Guatemala. To avoid traveler’s diarrhea and other water-borne diseases, drink bottled water and only eat peeled fruits like oranges and bananas. Bottled water (agua pura) is widely available in grocery stores, restaurants, and hotels. Boiling water for one minute or using iodine pills or a water filter will also purify water. Avoid fruits and veggies that require washing, and stay away from ice unless it’s made from purified water.
