Which national park is renowned worldwide and located in Fiordland?

Fiordland National Park is renowned worldwide for its stunning natural beauty and dramatic landscapes, which include spectacular fiords, steep mountains, and lush rainforests. It is one of New Zealand's largest national parks and a UNESCO World Heritage Site, recognized for its unique geological features and biodiversity. The park is home to iconic locations such as Milford Sound and Doubtful Sound, which attract visitors from around the globe for activities such as hiking, kayaking, and scenic cruises.

While the other parks mentioned have their own unique features and attract visitors, they do not have the same level of global recognition or the combination of dramatic landscapes and diverse ecosystems that make Fiordland National Park stand out. Abel Tasman National Park is well-known for its beautiful beaches and coastal walks, Aoraki/Mount Cook National Park is famous for its towering mountains and alpine scenery, and Arthur's Pass National Park is appreciated for its rugged mountain landscapes and hiking opportunities. However, none of them have the same iconic status associated with the fiords and natural wonders found in Fiordland.
