How Does Water Safety Work in Mexico?
Last verified: 2025-06 · Americas
1The Quick Answer
Do not drink tap water anywhere in Mexico — use bottled water, hotel garrafones, or a filtered water bottle.
2What You Need to Know
Tap water throughout Mexico is not safe to drink for tourists, and even many locals use purified water for drinking. Large refillable garrafón jugs (20 litres) are found in hotels and rental apartments; confirm your accommodation provides drinking water. Bottled water is cheap and available everywhere, including OXXO stores. Ice in tourist restaurants is generally made from purified water, but it is worth asking. Brushing teeth with tap water is usually fine for most travellers, but sensitive stomachs should use bottled water.
3Practical Tips
Practical Tips
- 1Buy a large garrafón from OXXO for around 15–20 pesos if your hotel does not supply drinking water
- 2A portable filtered water bottle (like LifeStraw or Grayl) can reduce plastic waste and costs on longer trips
- 3Ask restaurants whether their ice is made from purified water (agua purificada) if you are concerned
Important Warning
Drinking tap water in Mexico commonly causes traveller's diarrhoea. Stick to bottled or purified water for all drinking and in beverages.
