The lower Arthur Valley contains a more diverse forest due to higher rainfall and milder temperatures. Species present include silver beech, kamahi, miro, totara, fuchsia, mahoe and pate. Ferns, mosses and lichens are also abundant. The Milford Track has long been described as "the finest walk in the world". Located in southern New Zealand, this 3-4 day journey crosses a steep mountain pass pioneered by Quintin Mackinnon in 1888 entering into the heart of Fiordland.
