A scavenger hunt is a great way to get everyone on their feet to experience the surrounding landscape. You can take your scavenger hunt in one of two directions -- either plant your own objects and clues around the campsite, or else simply look for things already found in nature. Safety is an important consideration for scavenger hunts. If you have younger kids, pairing them up with an experienced camper is a good idea, so that they can learn what plants to avoid and how to safely navigate the terrain. Set a time when everyone must be back at the campsite, at least a couple of hours before dark. And, when you hand out the clues or list of things to find, give each team a whistle and a flashlight to use in case of emergency. Once everyone is back at the campsite, have each team do a show-and-tell with their findings.
