There's a debate as to whether you should drive the Cabot Trail clockwise or counterclockwise. The truth is, either direction is breathtaking. I drove the Cabot Trail clockwise and found the scenery amazing. I was driving solo and had to pull over a lot because I wanted to take photos, but there were tons of safe places to pull over in the park. Pick the directions that fits best into your travel plans - you won't be disappointed by the views no matter which way you take.
