This might appear to be high on the list, but in reality, people can often survive in many parts of the wild without shelter and food for a few days, but they will not survive without water.

Always plan to carry enough water for everyone in the group – in fact, take a little extra. It’s better to come home with more than to run out while on the trail. Keep in mind, if you’re traveling to drier, more arid climates then pack more than usual. Staying hydrated on the trail is extremely important.
