Often described as the "Finest Walk in the World". A 55 km moderate four day tramp, with up to seven hours walking on some of the days. It is a four day (three night) back to nature adventure through the spectacular scenery of Fiordland. The track starts at the head of Lake Te Anau, follows up the Clinton Valley over Mackinnon Pass (1,100m) and then down the Arthur River to Milford Sound.

A good standard of tramping fitness and equipment is required - you will need to walk 14 to 18 km a day, carry an 11-12kg pack over rocky surfaces with some stiff climbs and descents. Those with knee or hip problems could suffer on the long rough descent from MacKinnon Pass. Weather can vary from glorious sunshine to torrential rain and blizzards.

The group uses the three DoC Huts on the track. They are roomy, warm and comfortable, with open plan bunkrooms with good mattresses, gas cookers, flush toilets, but no showers. (Plenty of good swimming holes!) They take 40 people on each trip, which is the maximum number DoC allow in each day. They also supply the food, but you help to carry and cook it.
