Don't go unless the day is perfect. Guaranteed Great Destination. An open summit, a mountain blueberry patch, a firetower, a waterfall, a swimming hole are all acceptable desinations. Nothing less will do. They take the lead.
Kids hike twice as fast in the front as they do in the back.
Rotate the leader position. Let them figure out which way to go at the intersection. Lots of Snacks . Anything for a smile along the way, is my motto. Stick some candy bars in your pocket for a surprise desert at lunch, or as a special reward for reaching the destination.
