Start of some good tracks near Glenorchy. The Mount Judah track is pretty easy, only the climb to the Bonny Jean hut is quite steep. From the Bonny Jean hut it is less than an hour to the Heather Jock hut. You have fantastic views over lake Wakatipu and the mountains in the area.
A must for visitors to Glenorchy, walk up to the old Mine workings and explore the old roadways high above the top of the Lake.
