New Zealand is reminiscent of an unmade single bed, covered in folds and peaks. South Island is divided lengthways by the snow-covered Southern Alps and contains a succession of glaciers the longest of which stretches for almost 30km. Although North Island is a little less undulating its geothermal nature provides a prime example of NZ's inclusion within the Pacific Ring of Fire with active volcanoes Tongariro, Ngauruhoe and Ruapehu providing a breathtaking panorama. Making the three-hour crossing over Cook Strait allows travelers to skip between both islands with remote rivers, vast farmsteads and stunning coastal scenery adding to an exciting and varied itinerary.
