The Routeburn Track is a moderate Great Walk: 32 km over two to four days on well-graded, well-marked paths, with the main challenge being the climb to the exposed 1,255 m Harris Saddle and Fiordland's fast-changing weather. There is no technical scrambling within the Great Walk season (late October to April 2026), so fit hikers with multi-day experience manage it comfortably. Outside the season it becomes a serious alpine route.
The Routeburn's difficulty is often overestimated because it is an alpine traverse, but in season it is a graded, maintained track rather than a rugged tramp. The real variables are the saddle's exposure, the weather and the pack weight you carry between huts. This guide breaks down distance, ascent, terrain and conditions so you know what to expect in 2026.
How long and how steep is the Routeburn Track?
The track runs 32 km point-to-point, usually walked over three days with around 5–6 hours of walking each day and a total ascent of roughly 1,000 m. The biggest climb is to the Harris Saddle (1,255 m), reached on a steady graded path rather than a steep scramble. The full stage breakdown and elevation profile are on our Routeburn Track route guide. Most days are well within reach of anyone comfortable on a full-day hike, with the saddle day being the longest and most exposed.
What is the terrain like?
As a Great Walk, the Routeburn is maintained to a high standard with benched paths, boardwalks over wet ground and bridges over the major rivers during the season. You walk through beech forest in the valleys and open alpine tussock near the saddle, with some rocky, uneven sections up high. There is no exposure that requires hands, and the route is clearly poled. The footing is the easiest part of the trail; weather and altitude exposure are what raise the difficulty on the high section.
Routeburn difficulty factors
| Factor | Rating | Notes |
|---|---|---|
| Distance | Low–moderate | 32 km over 2–4 days |
| Ascent | Moderate | ~1,000 m to Harris Saddle |
| Terrain | Low | Graded, bridged in season |
| Weather/exposure | High | Exposed saddle, heavy rain |
Why weather is the main difficulty
Fiordland is one of the wettest places on Earth, and the Harris Saddle is fully exposed to it. Conditions can swing from sun to driving rain and cold wind within an hour, and the saddle offers no shelter, so the same easy path becomes genuinely demanding in a storm. This is why full waterproofs and warm layers are mandatory even in January. Check the forecast on MetService and current alerts on the Department of Conservation site before crossing the high section.
How fit do you need to be, and what to carry?
You should be able to walk 5–6 hours with a 10–14 kg pack on consecutive days. Regular full-day hiking in the months before your trip is enough preparation. A well-fitted pack makes the saddle climb far easier: the ventilated Osprey Atmos AG 65 and women's Osprey Aura AG 65 carry the load well, while lighter trampers favour the Zpacks Arc Blast 55L and heavier food loads suit the Deuter Aircontact Core 50+10. Our Routeburn packing list covers the essentials.
How to make the Routeburn easier
Three choices reduce the difficulty: walk it over three days rather than two to shorten each stage, book the Great Walk season (late October to April) when the path is bridged and graded, and pick a settled weather window for the saddle day. Walking guided with a hut operator removes logistics and lightens your pack. For a longer but lower-elevation alternative, the Heaphy Track spreads its distance more gently — see our Routeburn vs Heaphy comparison and the seasonal detail in our best time to hike the Routeburn guide.
How do you train for the Routeburn Track?
The Routeburn is moderate, so training focuses on comfortable multi-day hiking rather than peak fitness. Aim to walk for five to six hours carrying a 10-14 kg pack, then repeat it the next day, in the two months before your trip. If you can manage a loaded full-day hike followed by another the morning after, the three-day track will feel well within reach.
Build toward it gradually. Start with regular walks of one to two hours carrying a light pack, then lengthen one weekend hike while slowly adding weight until you are carrying close to your trail load. Practising back-to-back days is the most useful preparation, because the Routeburn's main physical demand is sustaining effort over consecutive days rather than any single hard climb. Include hill or stair sessions to prepare for the steady ascent to the Harris Saddle (1,255 m) and the descents either side, which are where knees feel the strain; trekking poles help here. Train in the boots and pack you will actually carry so you can fix any hot spots or fit issues before you fly to New Zealand. A little leg-strength work, such as step-ups and squats, adds resilience on the rocky alpine sections. Because the saddle is exposed to fast-changing weather, also build the habit of walking in rain and wind at home so a wet Fiordland day feels routine rather than daunting. With this modest preparation, most active hikers complete the Routeburn comfortably in the 2026 Great Walk season.
Managing the saddle day well is the single biggest factor in keeping the Routeburn comfortable. Start early so you cross the exposed high section in the calmer morning conditions, check the MetService forecast the night before, and be willing to adjust your pace or layers as the weather shifts. If a serious storm is forecast, hut wardens can advise on timing or whether to wait, since the Harris Saddle offers no shelter once you commit to it. Carrying trekking poles, eating and drinking regularly, and keeping your waterproofs accessible all make the climb and descent easier on body and mind. With a sensible three-day schedule and a watchful eye on the forecast, the Routeburn stays firmly in moderate territory for fit hikers throughout the 2026 Great Walk season.
Frequently Asked Questions
Is the Routeburn Track suitable for beginners?
Yes, fit beginners can walk the Routeburn during the Great Walk season, when the 32 km path is graded, bridged and well-marked. The main challenges are the exposed Harris Saddle and Fiordland's weather rather than technical terrain, so good waterproofs and basic multi-day fitness are the key requirements.
How many hours a day do you walk on the Routeburn?
Most trampers walk 5–6 hours a day over three days, with the Harris Saddle day being the longest and most exposed. Walking it in two days means longer 7–8 hour days, while three days leaves time for the side trip to Conical Hill (1,515 m).
Is the Routeburn harder than the Milford Track?
The two are similar in difficulty within the Great Walk season, both graded and bridged, though the Routeburn has more sustained alpine exposure on the Harris Saddle. The Milford is slightly longer at 53.5 km over four days. Neither requires technical skills in season.
What makes the Routeburn Track dangerous?
The main hazard is Fiordland's fast-changing weather on the exposed Harris Saddle, where rain, wind and cold can arrive within an hour. Outside the Great Walk season, removed bridges, high rivers and avalanche risk make it far more dangerous, which is why most hikers walk it from late October to April.
Do you need crampons for the Routeburn Track?
No, not during the Great Walk season, when the Harris Saddle is normally snow-free and the path is graded. Crampons and ice axes are only relevant for off-season alpine attempts between May and October, which require full alpine experience and equipment.
