This is a great example of a troll bridge and if you creep up carefully you may even see the troll who lives here. He usually divides his time between the tunnel and the bridge.
This little walk way is quite fun, and if you continue up the hill in a few minutes you will end up at the local duck pond, any ducks that venture down the stream this far become a troll meal
