Parts of Fiordland National Park are a designated Wilderness Area and aircraft landings are not permitted. The Wilderness Areas award special protection for large tracts of wild land containing natural features of such significance that they are preserved in their natural condition, without any man-made structures or facilities. Entry is usually restricted to foot travel, there are typically no tramping tracks, and in some cases, special permits are required, such as for several offshore islands and the Takahē Specially Protected Area in the Murchison Mountains.
