The Milford Track is a historic route from Milford Sound into the interior to Te Anu.  The full track is some 30 miles in length necessitating several overnight stays and a pick-up on the other end.  Glade House is the popular spot for the first night's stay.  Since we didn't have time for the entire hike, we hiked about three miles beyond Glade House and then turned around and retraced our steps.
