The North Island of New Zealand is blessed with spectacular scenery, ranging from bubbling thermal pools to fast flowing rivers. The best way to see all of this? Get up close and personal. This itinerary includes biking through Karangahake Gorge and hiking the Tongariro Crossing – one of the world's most famous one-day hikes – before jet boats and kayaks provide the transport along the Whanganui River. Mix in some bubbling mud and a traditional hangi dinner, and this is the perfect active introduction to New Zealand.
