I had no cell reception or contact with civilisation for four days while canoeing over 160 km of the Whanganui River as part of Te Araroa.
The Whanganui River along the Te Araroa trail. One of the Great Walks in New Zealand. Definitely the best four days of my life.
Waterfalls like these adorn the entire length of the Whanganui River winding through the mountains to the Tasman Sea.
