The Dunstan River is located in the Otago region of New Zealand's South Island. It flows through the scenic landscape of the Dunstan Valley, originating from the Hawkdun Range and eventually joining the Clutha River. The river is known for its clear waters and is popular for recreational activities such as fishing and kayaking. The river is named after the nearby Dunstan Mountains, which were named in the 19th century. The area surrounding the Dunstan River is rich in history, particularly related to the Central Otago gold rush. Today, it remains a picturesque spot for both locals and tourists seeking outdoor adventures.
