This depends on the individual’s weight, height, and activity level. However, a general guideline would be to take enough water to cover your body and drink regularly throughout the hike. For example, if you weigh 150 pounds and are 5’6″, you would need at least 3 liters of water per day (or about 12 cups). If you are carrying a full pack and are hiking strenuously for several hours each day, it is recommended that you bring more than 6 liters of water with you in case of emergencies.
