Stomach problems are the most common health issue for visitors to Nepal, and contaminated water is a common cause. The good news: safe water is easy to find if you know what to do.
Quick answer: no, don't drink tap water in Nepal, including in Kathmandu. Drink treated, filtered or boiled water. On treks, use a water filter or purification tablets, or buy boiled water from lodges, instead of plastic bottles. Use treated water for brushing your teeth too.
In cities
- Most hotels provide filtered drinking water; ask before drinking.
- Many cafés and shops in Thamel and Lakeside offer refills.
- Avoid ice unless you know it is made from treated water.
- Wash fruit in treated water, or peel it.
On treks
- Bring a reliable water filter or purifier bottle, or purification tablets or drops.
- Lodges sell boiled water, which you can treat again if you want extra safety.
- Some trekking areas have safe-water refill stations.
- Plastic bottles add to waste problems in the mountains; parts of the Everest region have restricted single-use plastic bottles.
Staying hydrated at altitude
Drinking enough water helps you cope with altitude. Aim for several litres a day on trek. See our altitude sickness guide.
If you get sick
Rest, drink oral rehydration solution and see a doctor if symptoms are severe or persist. See health and vaccinations for Nepal.
