You have two main options for drinking water: purchasing bottled mineral water or using a reusable bottle filled with boiling or sanitized water. Bottled and filtered water is available for purchase at teahouses and lodges along the trek, but it becomes more expensive as you gain altitude. To ensure safety, we recommend purifying water with iodine or other water treatment methods. Staying hydrated is crucial at higher elevations, so aim to drink at least 3 to 4 liters of water daily.
