Please keep in mind - if you are truly truly lost, the best advice I
can offer is to remain where you are and let the rescuers come to you. But
it's still a good idea to have a basic understanding of how to orient yourself
using only what you have. And all you have is the sun, the stars, and the nature
around you.
For a start, it may be a good idea to climb a hill, and get a good look around.
Try to see traces of human activity. If you see nothing, you should try to
figure out in what direction would be the best to travel. If you haven't got a
map, try to draw one if you can of the terrain in front of you, and try to mark
off where north is, using the methods below. If you have got a map, try to
determine where you are. Remember, you don't want to climb more hills than you
have to. Also you should carefully consider not to climb if you are very tired.
In that case you should consider staying where you are. Consult other sources
for information on how to make it easy for rescuers.
Let us start with the most accurate method. This method requires that you have a pretty clear sky, though, and takes a lot of time. One of the advantages is that you don't need any equipment. You would need a straight pole about 1 meter (or a yard) long, two small sticks or rocks, another stick (or rock) that needs to be a little sharp, and something that can act as a string.
In
the morning, at least before noon, the trick starts. Stick the long pole in the
ground, upright. The ground around the pole needs to be horizontal. Now, you can
place one of the little sticks in the ground exactly where the shadow
of the pole ends, like on the figure. Then tie the string to the base of the
pole, and tie the little, sharp stick, to the other end, so that when the string
is stretched it reaches exactly the little stick standing there in the soil.
Then, scratch half a circle in the soil with your sharp little stick, and
wait... Wait. Wait until the evening. During the day, the shadow will get
shorter and shorter, until noon, when it gets longer again. At noon, when the
shadow is at its shortest, you may want to mark the point. The shadow is now
pointing north (if you are north of 23.5 ° north). It is however not very easy
to see exactly when this is, but it is useful anyway. Finally, the shadow
reaches your circle again, and when it does, place your other little stick at
the spot where the shadow ends. If you haven't got a string, you could use a
pole that has the right length, or try to come up with some other improvised
solution. Just make sure what you draw is a circle.
Now, the line from the first stick
to the second is west-east, like on the figure. Actually, you may want to mark
points regularly, because any two points that have exactly the same distance
from the base of the pole will give the West-East line. If it is partly cloudy,
this may be a good idea.
There is a short, fast version of this one as well. This is only
approximate, though, and the further away from the equator you get, the more
inaccurate is it. You don't need the sharp stick and the string. Just wait 20
minutes between placing each of the sticks, and the line between the two sticks
will be approximately west-east, like on the figure. Often, you wouldn't need
anything more accurate.

At night, you can navigate after the stars. You should, however, be
careful with walking, it is easy to stumble and fall and get injured, and also
easy to lose sight of the stars as you go, and you might start going around in
circles. Often it will also be more physically and mentally demanding. In the
northern hemisphere, there is a star that is almost exactly in the north at all
times, the Polaris. It is pretty easy to find, if you know the "Big
Dipper". (Everybody knows the Big Dipper (or the Plough)?) Take the two stars at
the end of the "Big Dipper", and make an imaginary line "upwards", and extend it
five times the distance between the two stars. There you have it - Polaris. That
way is always north.
