The thumbnail is taken of a snake like river looking down a hill. The river mouth is at Wenderholm.
I always find this view interesting, if you go from Auckland to Whangarei up north you will miss Orewa, Wairewa, Wenderholm and this view. You go through the Johnson tunnels which you pay a toll for.
Looking down from this point is a river winding around mangroves and around the corner further north is Puhoi, a Bohemian town. After that, Warkworth.
