When hiking, stop frequently to observe plants, animals, or views. If you don't stop to look around, children will find hiking and looking at the ground pretty boring. Rest frequently when hiking. Just waiting for your children to catch up, then continuing does not allow time for rest. Let children lead and set their own pace.
Children lose fluids faster during exertion than adults, particularly during warm weather.
Don't wait until you are thirsty to offer liquids. Always carry a compass and a good map with the topography of the area you are hiking. Stop during your trip to look at the topography and see if youngsters can match it to the map. Teach them how to use a compass. Kids like to know what they're looking at and where they are.
