The Brown Wave is smooth with some rolling and very little climbing. This is a nice easy loop trail.
FATS consists of six individual loops, each with their own character and feel. There are two parking lots, the South Trailhead is the main parking lot, and the North Trailhead is adjacent to Big Rock and Tower. The southern loops are Brown Wave, Skinny, Great Wall, and Deep Step. Big Rock and Tower make up the northern loops.
