Ōpārara Basin Arches
The Ōpārara Basin Arches are a number of natural limestone tunnels formed by the Ōpārara River, in the Ōpārara Basin, New Zealand. The two most famous ones are the 'Ōpārara Arch', large enough for a multi-storey house, and the 'Moria Gate Arch', which is smaller in height.
The arches can be reached by a forestry road from the main road approximately 9 km north of Karamea. The 12 km road is rough but can be accessed by normal cars most of the year. A carpark with a modern open shelter and toilet facilities just before the bridge over the Ōpārara River is the starting point for walks of around an hour return to each of the arches. There are also mountain bike tracks and a mountain lake in the area.
