Fiordland National Park is in the southwest of New Zealand’s South Island. It’s known for the glacier-carved fiords of Doubtful and Milford sounds. A beech forest trail on the sandy Milford shore offers views of towering Mitre Peak. Nearby, the craggy Earl Mountains are reflected in the glassy surface of Mirror Lakes. On the Cleddau River, the Chasm Walk passes over bridges with views of powerful waterfalls.
