Camping Crafts and Activities

With the summer weather (or what's left of it) I have been thinking about camping, and how great it would be to have some woodsy crafts and activities to help enhance a child's camping experience.  Does anyone else enjoy camping out with their families?  Are there any activities you have tried in the woods that your children have enjoyed?  I have found that bringing along a magnifying glass/binnoculars provides a lot of opportunity for fun and exploration!
