How much water should I bring?

The amount of water to bring depends on the temperature and the length / difficulty of the hike you plan to do. Temperatures in the Vancouver area can reach more than 30 degrees celsius (86 degrees fahrenheit) during the summer months.

Many higher elevation gain hikes can be very strenuous and only accessible during the hot summer months. In addition, many of these trails have no water sources along them. For example, the Howe Sound Crest Trail that leads to popular hiking destinations like St. Mark's Summit, Unnecessary Mountain, and The Lions, has no water along the route. It's advisable to err on the side of caution and bring extra water during the high heat of summer and on longer hikes.

If you are planning a full day hike, bring at least 2 - 3 liters of water and consider bringing more on a really hot day.

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

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.
