Opportunities for hiking, nature-encounters and adventure tourism abound. Over the course of a short hike, you can walk from an ocean beach, through rainforest, along a turbulent river to the tongue of a glacier. You can view all manner of sea life from fur seals to albatross to sperm whales on the same day you ride New Zealand’s longest ziplines and see a coastal village taken over by thousands of vintage cars and campers of all description.
