Milford Sound at the mountainous north end of Fiordland National Park is the classic fiord - a deep water inlet between steep sided high mountains. Milford Sound is a middle-sized fiord at around 13 kms in length and it is famous for its dramatic scenery, especially Mitre Peak. This fiord is the most accessible of Fiordland National Park’s 14 fiords and it can be reached by road (coach or car) or by flight connections from Queenstown.
Doubtful Sound is located in the heart of Fiordland National Park where the mountains are still very impressive but not as high as Milford Sound. Doubtful Sound is three times longer and has a sea surface area roughly ten times larger than Milford Sound. Its three arms are Hall, Crooked and First Arm. It is famous for its wilderness scenery and wildlife sightings. To travel to Doubtful Sound visitors first take a launch trip across Lake Manapouri and coach over Wilmot Pass.
Visitors with enough time choose to experience both fiords as they have different characters.
