Not quite the grand canyon, the Manawatu Gorge is well known in New Zealand. There has been extensive work due to land slips with bad weather and rain. I can remember being really scared travelling through here as a child. Its not so bad now. You can see the road on the right (photo was taken from the car) and on the left you can see a tunnel that the train goes through. The road is one side, and the train the other. Luckily I have experienced travelling through on both sides. On the train, you look down in places and its just a drop. Was kind of scary.
