Milford vs Routeburn vs Kepler: which Fiordland walk?
Three of the most famous Great Walks, in the same park. Here is how they compare on distance, days, what is hard, and what to do if the Milford is full.
By Nathan Gee, Peaksted coach · Updated · 5 min readPeople ask which one is hardest. The honest answer is that they are close, and each is hard in a different place. The better question is which one you can book, and which test you would rather train for.
Milford for the classic, Routeburn if you are short on time or want the most alpine, Kepler if you want a loop from Te Anau. All three need comfortable six-hour days and legs that can come down.
The three at a glance
Pick a walk to see the numbers. All figures follow DOC and are rounded.
Milford Track
The classic. Gentle gradients, long days and one big descent, in a very wet valley.
- DistanceAbout 53.5 km
- Time4 days, 3 nights
- ShapeOne way, boat at each end
- High point1,154 m, Mackinnon Pass
- The hard partA 1,000 m descent on day three, then an 18 km finish
- Season 2026-271 November to 30 April
Routeburn Track
The shortest and the most alpine. Less time, but the climb and the exposure are real.
- DistanceAbout 33 km
- TimeMost walkers take 3 days, 2 nights
- ShapeOne way, transport at each end
- High point1,255 m, Harris Saddle
- The hard partA sustained climb to the saddle and open, exposed tops
- Season 2026-271 November to 30 April
Kepler Track
The longest, and a loop, so the logistics are easy. The ridge day is the one to respect.
- DistanceAbout 60 km
- TimeMost walkers take 4 days, 3 nights
- ShapeA loop from Te Anau
- High point1,472 m with the Luxmore summit side trip
- The hard partA big climb on day one, then an open alpine ridge
- Season 2026-2727 October to 30 April
How they compare on your legs
Four things we train for, from low to very high. Our reading, not DOC’s grades.
Milford is the only one where the descent is the headline. Routeburn is the shortest, with the most sustained climb. Kepler is longest, so it adds up.
Which one is for you?
Milford Track
The famous one, with gentle gradients and one big day. Book first, then train around the dates you get.
Routeburn Track
About 33 km over two or three days. It is the quickest of the three, and the most alpine.
Kepler Track
No transport shuffle, and the biggest ridge day of the three. It is the longest, so the days add up.
Routeburn or Milford
Both have kinder daily gradients than the Kepler's first day. Train for the descent either way.
Plan B that is not second best
Peak dates sell out on all three. A few things that help.
- Check DOC againReleased dates and cancellations can free up space, so it is worth checking in the weeks before.
- Try the shoulder seasonThe start and end of the season are quieter than the peak, and the weather can be just as good.
- Look at Routeburn or KeplerSimilar scenery, a similar demand on your legs, and the same training works for both.

Milford vs Routeburn vs Kepler: FAQ
Which is harder: Milford, Routeburn or Kepler?
They are close, and each is hard in a different way. The Milford's hard part is the 1,000 m descent on day three, the Routeburn's is the climb to Harris Saddle and the exposure, and the Kepler's is the long climb on day one and the open ridge. For most people the Kepler is the most demanding overall because it is the longest.
Which Fiordland walk is best for a first multi-day walk?
The Routeburn is the shortest, which makes it the quickest to commit to, and the Milford has gentle gradients. All three need comfortable six-hour days, so the best choice is the one you can book and train for.
What if Milford Track is fully booked?
Check DOC for released dates and cancellations, and consider the Routeburn or Kepler, which have similar scenery and a similar demand on your legs. Peak dates book out on all of them, so a shoulder-season date can help.
Can you do more than one of them?
Yes, they are all in the same region, and many people combine two in a trip. Allow rest days between them, because the demands add up.
Does the training differ between the three?
Not much. All three reward strong legs, an easy engine and practice at back-to-back days. The Milford leans on the descent, the Routeburn on the climb and the Kepler on the long first day.
How early do I need to book?
Great Walk bookings open months before the season and popular dates go quickly. Check DOC for the release dates for each track, and book before you plan the training.

DOC does not state total distances for the Routeburn or Kepler, so we have added the published section distances. Conditions, fees and closures change, so check DOC.
