Hiking is an activity that appeals more to adults than children.
On the other hand, when I’ve volunteered to take groups of kids on day hikes, I estimate about a third really get into it. They tell me they’d like to do more and longer trips.
Perhaps children simply have too little exposure to hiking. And too much exposure to TV.
Are there any gift giving holidays coming up?
