How much water should I drink when trekking in high altitudes?

When trekking in high altitudes, such as when you climb Kilimanjaro, it is generally recommendable to drink lots of water of up to three litres per day. This helps to acclimatize to the high altitude. However, it is not recommendable to drink much more than three litres of water per day as excessive liquid consumption flushes vital electrolytes from your system. If you drink more than three litres, it is essential that you replenish your lost electrolytes with supplements.
