Arthur's Pass National Park is located in the upper half of New Zealand's South Island and it's northwestern edge is the border between the regions of Canterbury and Westland. Arthur's Pass (924 m) is the second highest mountain pass in the South Island, just after Canterbury's Porter's Pass (939 m).
Arthur's Pass connects Christchurch on the east coast of the South Island with Greymouth in Westland directly through the Southern Alps. The park covers an area of 114,400 ha of mountainous landscape, glaciated U-shaped valleys, beech forests and wide riverbeds. Arthur's Pass was the first national park to be established in the South Island and was opened in 1929.
Arthur's Pass Village is a high altitude settlement and is closely situated to the Alpine Fault. This area frequently experiences earthquakes and rockfall hazards accordingly which is a challenge for civil engineering.
