Milford Sound is a fiord in the southwest of New Zealand’s South Island. Of the thirteen fiords in the Fiordland National Park, Milford Sound is the most famous and accessible. The road to Milford is a spectacular alpine journey and is one of the world’s finest drives. It’s known for towering Mitre Peak, plus rainforests and waterfalls like Stirling and Bowen falls, which plummet down its sheer sides. The fiord is home to fur seal colonies, penguins and dolphins. Milford Discovery Centre and Underwater Observatory offer views of rare black coral and other marine life. Boat tours are a popular way to explore.
