Can I drink the water in Vietnam?

Drinking tap water isn't recommended in Vietnam. Although, bottled water is always available at restaurants, vendors or 24-hour shops, for environmental reasons, it’s advisable to avoid buying bottled water. Consider bringing your own water bottle to refill along the way. When unable to avoid bottled water it is better to buy the largest available and distribute into your smaller bottle for the day. It’s wise also to avoid ice in your drinks.
