The Buller Gorge is a gorge located in the northwest of the South Island of New Zealand. Travelling south from Nelson or Blenheim, the gorge is the start of the West Coast.

The Buller River flows through a deep canyon between Murchison and Westport. The resulting spectacular gorge is broken into two sections, the Upper Buller Gorge and Lower Buller Gorge.

The Stillwater-Westport Line railway runs through the gorge. New Zealand’s longest swing bridge at 110 m length spans the river 14 km west of Murchison. More adventurous visitors can try the zip-line across the gorge while there are also several short bush walks.
