Use a compass: North points to N, South opposite, East right, West left
Use the sun: rises in the East and sets in the West
In the morning, the sun is in the East
In the evening, the sun is in the West
In the Northern Hemisphere, moss often grows more on the north side of trees
At night, find the North Star to locate North
Stand with your right hand toward the East; your left hand will point West
Use a map: top is usually North, bottom is South, right is East, left is West
