Any, most harmless, walk in an unfamiliar area, especially in the woods, can have dire consequences. For example, a man went into the woods alone or with a friend and got lost, or simply they have any doubt that he is going the right way. If it was not very far away from populated areas, then, first of all, to stop.
Do not try to look for the road, running in different directions. You only further confuse toward. Sit down on a stump and mentally imagine the entire route covered. Try to remember all the trails, nests, fallen trees, all of what you've been paying attention along the way. Remember the last will take on an unfamiliar part of the way and try to determine the way to it. Remember which side was the sun or the moon, which they were going, or the wind blew clouds. Listen: to find people to help sound. Tractor audible for 3-4 km, barking dogs — 2-3 km, train noise — for 10 km.
