The tap water in Nepal is unsafe to drink for foreigners’ people. From the local tap water, different problems can be seen by hikers and trekkers so, clean and safe water is important to drink. Most of the treks provide bottled mineral water which cost a high amount but is safe. In some places where plastics are not allowed, they sell safe drinking water. There are safe drinking water stations in each village. In those places where there is no bottled water and safe drinking water please ask for boiled water. The boiled water also costs you but is good for your health and avoids problems.
