The Secret Triwizard Challenge

Your Incarcerous spell hits the spider's front four legs, tripping it. It rolls past, barely missing you. You tear yourself from the sticky webs and run past the clearing, into the winding maze again.
Eventually, you come to a fork in the road. To the left, you see darkness, but a faint blue light glows further down the path. To the right, you can see a lush meadow and large boulders. Ahead, you see huge paw prints in the dirt. Which way do you go?
