My partner and I will be heading to NZ in August this year. We are wanting to do a glacier hike but can't really afford to do both as we have lots of other activities we want to do during this trip. We intend to visit the Franz Joseph hot pools either way but are wondering what glacier is best to do a hike on? We were looking at the full day fox glacier tour or the Franz Joseph and hot pools tour. Not concerned about the added entry to hot pools just want to do the best hike out of the two. I know fox is a bigger Glacier but which is more interesting to hike on? i.e caves, views etc. Have heard that Franz Joseph have a pre selected route but Fox Glaciers determine the route by the weather etc. Any advice/ feedback would be greatly appreciated!!
