Although mentioned in the middle of the list, it is the most prominent thing you should take while hiking. It is what should keep you running. You must, in fact, revere this item of the list. But to carry barrels of water to keep you hydrated is almost impossible and impractical. So you need to check about the shops close by and whether they have water on sale. In most cases, water will be available. But what you cannot be sure of is the quality of the water. You can even check with Bandarawela Hotel, or any other Bandarawela hotels, about the stores close by. It is better if you can take water purification tablets or filters to avoid any health hazards during the journey.
