The small town of Kingston sits at the southern end of Lake Wakatipu, and is a pretty low key place without the tourist scene around Queenstown. The short but steep Shirt Tail Track is one way to get above the town and enjoy the scenery if you are in the area, and the drive down from Queenstown is also nice.
The Te Kere Haka track is another flat option that runs alongside the foreshore of Lake Wakatipu; we did a bit of this but I don’t think we had time to make it to the end. Both walks are nice enough, but there’s much more specular scenery around Queenstown, and at the northern end of the lake around Glenorchy.
