Stewart Island is New Zealand's third island in size.. It's located South of the South Island. Only a handful of people live there. Stewart Island is a walkers heaven. It has 2 main tracks. The first is the Raikura Track, which is an official Great Walk and immensely popular. The second is called the North West Circuit. It can take as many as 10 days to complete it. We did a part of the North West Circuit. We were dropped off by a water taxi at Fred's Camp Hut and walked to Freshwater Landing and then on to Mason Bay. Mason Bay lies on the west side of Stewart Island. It was an unforgettable experience..
