The Inangahua River is located on the South Island of New Zealand. It flows through the West Coast region, starting in the Paparoa Range and eventually joining the Buller River. The river is approximately 50 kilometers long and is known for its scenic beauty and recreational opportunities, including fishing and kayaking. The river's basin is surrounded by lush forests and mountainous terrain, making it a popular spot for outdoor enthusiasts. The Inangahua Valley, through which the river flows, is also rich in history, particularly related to the gold mining era of the 19th century, which attracted many settlers to the area.
