Manawatu-Wanganui

Tongariro National Park's three volcanoes remain genuinely active — Ruapehu last erupted significantly in 1995-96 and Ngauruhoe as recently as 1975 — and the landscape the Tongariro Alpine Crossing traverses is a direct, visible product of that ongoing activity: bare volcanic rock, steaming vents and the strikingly turquoise Emerald Lakes, coloured by dissolved minerals leaching from the surrounding volcanic ground. The one-day crossing, roughly 19.4 kilometres with significant elevation gain, requires no technical climbing but does demand genuine fitness and, given the exposed alpine terrain, close attention to weather forecasts — conditions can turn dangerous quickly even in summer. Ngauruhoe's distinctive symmetrical cone, visible throughout much of the walk, doubled as Mount Doom in the Lord of the Rings films, a detail that draws a specific subset of hikers alongside those there purely for the volcanic scenery.

The Whanganui River Journey is the only one of New Zealand's 11 Great Walks completed entirely by canoe rather than on foot, following the Whanganui River — New Zealand's longest navigable river — through steep, densely forested gorges for three to five days depending on the chosen route. The river carries deep significance for the iwi of the Whanganui region, and paddlers pass historic marae, abandoned colonial-era river port settlements from a short-lived early-20th-century tourism boom, and the striking “Bridge to Nowhere,” a 1936 concrete bridge stranded in bush after the farming settlement it once served was abandoned. DOC-managed huts and campsites along the route provide the same infrastructure as the walking Great Walks, adapted for a paddling itinerary.
