How Does Water Safety Work in Peru?
Last verified: 2025-06 · Americas
1The Quick Answer
Never drink tap water anywhere in Peru — bottled or purified water is essential throughout the country, and altitude significantly increases your dehydration risk.
2What You Need to Know
Tap water across all of Peru is unsafe for drinking and even brushing teeth with tap water can cause illness for travellers without local immunity. Always buy sealed bottled water or purify water using tablets, a UV pen, or a reliable filter. At high altitude, your body dehydrates faster than at sea level — aim to drink at least 3–4 litres per day in Cusco and on treks. Trekkers on the Inca Trail should carry water purification tablets as the only reliable source of safe water in remote sections.
3Practical Tips
Practical Tips
- 1Carry a reusable water bottle with a built-in filter (such as a LifeStraw bottle) to reduce plastic waste and save money on constant bottled water purchases.
- 2In restaurants, specifically ask for bottled water ('agua sin gas, botella' or 'agua con gas') and confirm it is sealed before drinking.
- 3Ice in drinks at tourist restaurants in Lima and Cusco is generally made from purified water, but avoid ice at very cheap local eateries.
Important Warning
Traveller's diarrhea from contaminated water is one of the most common illnesses in Peru; it can quickly become serious at altitude where dehydration is accelerated.
