The Milford Track is a 53 km hike, and it takes four days and three nights including the bus and boat trips to the start and finish of the track. There are huts along the track for independent walkers with cold running water (but no showers), gas stoves, and bunks with mattresses, so all you need to pack in aside from your clothes are a sleeping bag, food, and cooking gear. Pretty cruisy if you are a serious tramper, ("tramping" being the local term for hiking). The walk itself is quite manageable for anyone of average fitness, with only one day containing much elevation gain or loss, and the track itself is very clearly marked. All you really need to concentrate on is enjoying the view! Hope you like the pictures :)
