We only heard about this from a local and it was really worht doing. A cruise along a mirror like water way through the rainforest gave me some of the best photos of my holiday. This is located on new Zealand;s Gold Coast in the central part of the West Coast on the south island. They said you can do some trout fishing on ths trip aswell. We didnt fish but the local we spoke to said it was a well know river the locals use for trout fishing.
