I would consider this canyon one of the best routes in New Zealand simply for its immensity and sheer beauty. It is extremely deep, narrow, and under high water conditions can prove to be challenging. The drops and abseils are not particularly challenging, which contributes to its relatively low technical rating. The approach on this route is absolutely terrible and will kick your ass no matter how you do it. There is one only or two ways that will not require ropes on the approach and it is quite a vague and hazy to explain how, since the terrain on the approach is very convoluted and changes significantly depending how high or low on the ridge you happen to be. If you do happen to make your way to the drop in point, take your time and enjoy; it is one of the best routes in the world.
