Walking during the day is fun in itself but at night new creatures and sounds arise and it can be just as fun. We love walking in the evening. It helps get out any extra energy before bedtime and gives kids something to think of as they drift off to sleep. The sky changes different colors and the moon shines different shapes. A extra thing we like to do is to bring glo sticks. It also helps keep kids safe as they glo in the dark. (of course flash lights work too but I found for little kids it wasn't always easy to them not to shine it at passing cars or faces.) At night owls come out with different sounds and spiders start to make webs for the night. Another idea is to do a nighttime scavenger hunt. It can be the same things you would look for in the day just a little harder cause its turning dark.
