I went a did yet another tramp, this is the 4th in NZ, this one only 32km but up to 1300m in the sky. Its all up and then all down, no flat at all. But my what amazing views. Well worth it. The first night I spent on MacKenzie lake, in the morning it was like a mirror, perfectly still. The next night I spent on the Routeburn flats, I had pretty much the whole afternoon to lounge around in the sun and read a book.
