Blue River (New Zealand)

The Blue River is a small river in the South Island of New Zealand. It flows its entire length within the Mount Aspiring National Park, and although on the southeastern side of the main divide, the river is within the boundaries of the West Coast region for its entire length.

The headwaters are southeast of the main range of the Southern Alps near the mountain Eyetooth, with the smaller Blue River North Branch and South Branch joining the main Blue River later. Shortly before flowing into the Makarora River, the river passes through a narrow gorge.

At its confluence with the Makarora River, the aptly named Blue Pools are the destination of a popular short walk from, with a bridge crossing the Blue River and providing good views upstream into the gorge and downstream over the river flowing into Makarora River. The longer Blue Valley tramping track leads deep into the Blue River Valley and along most of the length of the river.
