From TeKuiti you would usually turn right and go up to 8 mile junction (insert Eminem song here) then left to Taumaranui and on through to National Park (and then another 30km to our overnight destination Raetahi). So of course we turned left over the railway lines, then right and onto some amazing winding sealed 'B' roads, then off those and onto gravel roads (that I had seen before but never knew where they joined into) which ran parralel to the highway main route, visible on the other side of the river and railway.
