Before you head off on a walking tour, familiarize yourself with the trail system used in the area. Trails are often blazed with different colors and shapes depending on the area. For information about the blazes, check Walk Directions. Generally, in the Northeast U.S., three of the blazes placed together in a triangle indicates the beginning or end of a trail. One blaze placed atop another indicates a curve in the trail. If the top blaze is to the right of the lower blaze, the trail goes right, and vice-versa. Different blaze systems exist in other parts of the country or world.
If the instructions tell you to follow the blazes during a certain portion of a walking tour, don’t change trails unless directed to do so by the blazes. If you’re not sure you’re on the right trail, retrace your steps until you pick up a blaze, then turn around and resume your walking tour, keeping an eye out for the next blaze.
