In the regular cases, you never need it. You have a trail, you have a map, and it is good enough. However, there are situations, when it is a life saver. Once we lost in the mountains with my friend. We have the good orientation from the sun, so we finally found our wat back to the camp. But, what if it was cloudy than? Anyway, even after this adventure I do not take compass with me: stupid never learns, even on his own mistakes...
