The fitter you are the more you will enjoy yourself, so a good level of fitness and strength is necessary.
Find out more about the walk and what is involved;
Day 1, Routeburn Shelter to Routeburn Falls Hut, 8.8km
From the carpark, cross a swing bridge to begin the track itself.
Meander through beautiful beech forest before walking above the Routeburn Gorge. A second swing bridge takes walkers to open, grassy flats, before the track climbs steadily through more beech forest.
Cross two more swing bridges & enjoy the huge views of the valley below before arriving at Routeburn Falls Hut(opens in new window).
Day 2, Routeburn Falls Hut to Lake McKenzie Hut, 11.3km
This morning's walk climbs steadily to the outlet of the river at Lake Harris - don't forget to occasionally stop and look behind you for great views of the Routeburn Valley.
The long climb to the Harris Saddle, the highest point of the track, is worth every step. Beautiful Lake Harris greets you with waters that will be either deep blue or slate grey, depending on the weather. The saddle has many other pretty little tarns hidden in its folds.
From the top of the saddle, you are surrounded by mountains - the Darren Range, Mount Madeline (2,537m) and Mount Tutoko (2,746m), just to mention a few.
The track then traverses down towards the Hollyford Valley, where Lake McKenzie becomes visible. Once through the bush walkers arrive at Lake Mackenzie Hut(opens in new window).
Day 3, Lake McKenzie Hut to The Divide, 12km
Leaving Lake Mackenzie Hut, the track winds through grassy flats dotted with trees before coming to the spectacular Earland Falls (174m).
The track then continues on a gradual descent to the Lake Howden Hut, the perfect place to stop for lunch. From here, the track climbs steadily to the Key Summit Track turnoff.
Key Summit provides panoramic views over the Humboldt and Darran Mountains. Walkers then head gradually downhill through silver beech forest to the divide on Milford Road.
