Just driving around is beautiful, much spectacular scenery, especially the mountains. We don’t really have anything like it in Aus. Visiting the Franz Joseph glacier was a highlight. You can see it by booking a guided walk. The ice formations and blue ice colour is very interesting and beautiful. I saw it about 15 years so I don’t know how it is now, because warming and glacier retreating etc, but if it’s still available to see it I would highly recommend it. (Who knows how long it will be there for?)
