What is the situation with drinking water throughout the trek?
The water will be boiled during the whole trip. However, you can buy water purification tablets in the drugstores here, if you prefer. Another option would be to buy mineral water for the Inca Trail in Cuzco and bring it with you (but that will add kilos to your luggage) or buy mineral water on the Inca Trail that will be a little more expensive, but it’s really worth the extra cents, as they bring it to you in the middle of nowhere.
