Finding direction without a compass:

Celestial navigation






Using stars

Polaris (north star, pole star)

In the northern hemisphere, the pole star can be used to indicate north.
Be aware that the pole star is NOT the brightest star. It can be found using other stars. This needs to be practiced - in an emergency, if you have not done it before, you are unlikely to find (or therefore use) the correct star.

Using the moon




A rough guide to direction can be found in a crescent moon - a line joining the "horns" of the crescent will point to south on the horizon. This method is least accurate when the moon is close to the horizon.
