Whanganui River, New Zealand

With a length of 290 km, the Whanganui is the country's third-longest river. Much of the land to either side of the river's upper reaches is part of the Whanganui National Park, though the river itself is not part of the park.

The river rises on the northern slopes of Mount Tongariro, one of the three active volcanoes of the central plateau, and close to Lake Rotoaira. It flows to the north-west before turning south-west at Taumarunui. From here it runs through the rough, bush-clad hill country of the King Country before turning south-east and flowing past the small settlements of Pipiriki and Jerusalem, before reaching the coast at Whanganui. It is the country's longest navigable river.
