Q: How much water should I bring?

At least 2 - 3 liters for a full day hike is advisable.

General guidelines from the Dietitians of Canada for an average day with about one hour of physical activity:

Age: Fluid in litres (or cups)

Child 1-8 years: 1.3 - 1.7 L (6 c)

Boys, 9-18 years: 2.4 - 3.3 L (10-13 c)

Girls, 9-18 years: 2.1 - 2.3 L (8-9 c)

Adult males: 3.7 L (15 c)

Adult females: 2.7 L (11 c)

Everyone needs more fluids during physical activity, hot or humid weather, cold dry weather and higher altitudes. Plan regular fluid intake while hiking to avoid dehydration. Drink water throughout the day.
