Final answer:
The best way to keep your bearings while hiking in unfamiliar terrain is to use a compass and a map. Relying on instincts, following footprints, or using the position of the sun may not be accurate or reliable.
Step-by-step explanation:
The best way to keep your bearings when hiking in unfamiliar terrain is to use a compass and a map. A compass can help you determine the cardinal directions (north, south, east, west) by using the Earth's magnetic field. A map can provide you with a visual representation of the terrain, landmarks, and other features.
Relying on your instincts can be risky as they may not always be accurate, especially in a new environment. Following the path with the most footprints may lead you off course if those footprints were left by someone who was also lost. Similarly, using the position of the sun can only give you a general sense of direction during the day and is not reliable when it's cloudy or during nighttime.
