We came up with a rope and steel stake system which was relatively low cost, easy to install and semi-permanent that looks and works great.
Here's why and how we did it...
Step 1: Theory
Simply put, a labyrinth is similar to a maze, however unlike a maze which has branches, a labyrinth is one single path, and as such, there are no wrong turns. A labyrinth's path is supposed to be easy to follow and is not constructed with the intention of making the participant feel confused or lost. Instead, one of the intended outcomes is quite the opposite, as labyrinths are used as meditation tools, to calm and focus the participant.
Generally speaking, the labyrinth has a single opening, you walk in a back and forth pattern on the path until you reach the end. At the end, you turn around and walk out along the same path you came in on. It's pretty straight forward when you see this in person. Most labyrinths don't come with signs, or directions, they are "just there" for people to walk on and enjoy.
Why someone would want to walk on a labyrinth is a simple question with many different answers. Labyrinths are found all over. Sometimes they have religious affiliations, others are simply just installed in a natural and beautiful setting like a park. Some walk them to feel a sense of calm, meditation and clarity, others probably just think of it as a fun path to stroll on. No matter why you may find yourself walking a labyrinth, it's generally agreed that labyrinths are beautiful and interesting creations. In short, labyrinths are built to be enjoyed, and that's certainly why we built ours.
Wikipedia's labyrinth page has lots of interesting information on the history of labyrinths and their uses. While labyrinths warrant a more detailed explanation then what's offered here, this Instructable is more concerned with how to make one and assumes that if you are reading this, you've already got some interest in making one yourself, or at least learning how one is made, and can research more about the derivations and properties of labyrinths from other resources.
