St. Michael's Universiy Church has it's own little labyrinth. Labyrinths are a meditative device found near many churches. What makes this one special is it's connection to the student community. While you are walking through the maze, thinking about life, the rows of rocks will remind you of the many students that make up this community, and their love of Isla Vista.
You are looking for a "tube" cache under one of the painted rocks.
