The Mangapurua/Kaiwhakauka Track is a 40km trail between Whakahoro and the Mangapurua Landing, both on the Whanganui River. The track runs along the Mangapurua and Kaiwhakauka Streams (both Whanganui River tributaries). Between these valleys a side track leads to the 663m Mangapurua Trig, the area’s highest point, from which cloudless views extend to the Tongariro and Egmont National Park volcanoes. The route also passes the amazing Bridge to Nowhere. Walking the track takes 20 hours (three to four days).
The Whakahoro Bunkroom at the Whakahoro end of the track is the only hut, but there’s plenty of good camping (free to $14). There’s road access to the track both at the Whakahoro end, and from a side track from the end of the Ruatiti Valley–Ohura Rd (from Raetihi).
