Fatman's Rock is what gives the trail its name. There are a couple large boulders in the middle of the trail that you have to make your way between. Legend has it that you will get stuck if you are fat; in reality, the gap isn't going to be a tight squeeze for anyone. The rocks make for a pretty cool trail feature, though!
