Children need a quart of water for every two hours of hiking. |
How much water should you take? Adults need at least a quart for every two hours hiking. Children need to drink about a quart every two hours of walking and more if the weather is hot, dry or cold and if at a high altitude. To keep kids hydrated, have them drink at every rest stop.
Don’t presume there will be water on the hiking trail. Most trails outside of urban areas lack such public amenities. In addition, don’t drink water from local streams, lakes, rivers or ponds. There’s no way to tell if local water is safe or not. As soon as you've consumed half of your water supply, you should turn around for the vehicle.
