Fiordland National Park occupies the southwest corner of the South Island of New Zealand. It is the largest of the 14 national parks in New Zealand, with an area of 12,500 km², and a major part of the Te Wahipounamu World Heritage site. The park is administered by the Department of Conservation.
The wildlife in this area include dolphins, seals and birds. Introduced species include mice, rats, hare and deer. Among the birds are the Kakapo, the only flightless parrot in the world. Also there is the kiwi, which is native to New Zealand. The Park is heavily forested with Nothofagus trees, a large variety of understory shrubs and ferns being present; examples of the forest floor vegetation include Crown Fern, Blechnum discolor.
The park is a popular destination for alpine climbers and especially for trampers, with the Milford, Kepler, Hollyford and Routeburn Tracks all in or close to the park. Fiordland is a challenging tramping destination. There are few tracks. Off-track travel relies on following deer trails. Sandflies, flooding and poor weather are a hazard. Other tourists are attracted to areas such as Milford Sound.
