What is the name of the famous hiking destination in Fiordland?

The Milford Track is renowned as one of New Zealand's most iconic hiking destinations, located in the stunning Fiordland National Park. This track is celebrated for its breathtaking scenery, which includes lush rainforests, majestic mountains, and spectacular waterfalls.

The journey typically takes about four days to complete, covering approximately 53.5 kilometers (33 miles), and it culminates at the stunning Milford Sound, offering hikers opportunities to see remarkable natural beauty and unique wildlife. The track is often referred to as "the finest walk in the world," and it draws numerous trekkers each year, making it a crucial part of New Zealand's hiking and tourism landscape.

While Routeburn Track and Abel Tasman Track are also popular hiking trails, they are not specifically situated within Fiordland, and the Caples Track, while scenic, is less famous than the Milford Track. Thus, the recognition and prominence of the Milford Track make it the correct answer.
