Plastic Mineral water in the ABC trek is banned for environmental concern and we are opposed to the use of disposable plastic bottles on any of our trips to Nepal Himalayas. With no extra charge, our staff will supply you with appropriately boiled water every morning and evening for which at least 2 metal or plastic Nalgene bottles are recommended. In case you run out of the water provided you can always buy boiled and filtered water from the tea houses along the way at minimal charges.
