Hiking Trails
    Trails are designed to have a gentle slope that allows for the maximum sustainable pace of travel, which can be up to 8% slope at 2 mph plus an hour for each thousand feet of elevation change.  An additional constraint is to cross contour lines at less than a 30^o angle, which along with several other features helps to keep water off the trail, otherwise the trail will quickly be destroyed by erosion where the incline trail at the Walls of Jericho is a prime example.  One of the most easily recognizable features is a switchback, and it is important not to take shortcuts to avoid them because this results in most of the unnecessary damage to a trail as well as the surrounding vegetation.  The trail corridor is cleared of vegetation that would interfere with travel and attention will be paid to how limbs are pruned so that future maintenance is kept to a minimum.

Labyrinths and Mazes
    The most obvious difference in labyrinths and mazes is that labyrinths consist of a single path where you cannot get lost while mazes have branches that may be dead ends thus these decision points make mazes puzzles while a labyrinth could better be described as a journey.

Garden Paths
    The the goal of garden paths is getting from one area to another while providing an interesting vista along the way as well as separating beds into manageable sizes.  There are traditions and even superstitions that dictate these aesthetics in certain themed gardens such as Japanese tea gardens and Biblical gardens where ironically the paths are curved or zigzagged rather than on the straight and narrow because it is believed that the Devil can only travel in a line.  Another common element of themed gardens is water features.
