For the youngest, this is sufficient and gives the child exercise, fun and some exposure to maps, as well as confidence in being alone in the woods. Even at this simplest level, however, children can be taught map symbols, map colors and simple orienteering skills. For children ready for more challenge, the locations of the controls can be left off the map. The child must figure out where the controls should be on the map. Alternatively, some controls can be placed off the string inside the loop formed by the string.
Many variations are possible.
