For most of its 150km journey from the Southern Alps to the Pacific Ocean, the braided Rakaia River flows through a wide shingle bed. But for a short distance it goes through a canyon, known as the Rakaia Gorge. On its northern side is the Rakaia Gorge Walkway, a scenic 10km walk through bush and beside the river. This springtime the nearby mountains add to the scene with a sprinkling of late snow.
Here is a map of the Rakaia Gorge Walk that I have copied from the NZ Frenzy website. Click on map to enlarge. There is further information about the walkway at the NZ Frenzy website.
