A crossing, not a loop: Mount Aspiring to Fiordland
The Routeburn Track is one of New Zealand’s ten Great Walks, and the one that starts closest to Queenstown. It runs 32km one way between the Routeburn Shelter, near Glenorchy at the head of Lake Wakatipu, and the Divide on the Milford Road, deep in Fiordland National Park. In between it climbs out of beech forest, crosses the Harris Saddle above the bushline, and drops past a string of alpine lakes on the Fiordland side. For most of its length the track sits on the boundary of two national parks — Mount Aspiring on the Glenorchy side, Fiordland on the other — which is part of why the scenery changes so much over three days.
Most people walk it in 2 to 4 days, staying in Department of Conservation (DOC) huts along the way. It is not a loop: you finish a long way from where you started, which shapes almost every practical decision on this page, from transport to how many days to allow. There is also a much shorter way to see a slice of it — the Key Summit day walk — covered further down.
Book huts before you book anything else for this trip. Routeburn bunks for the Great Walks season open for booking in May, for the season that starts the following October, and popular dates sell out within hours of booking opening. If a Routeburn crossing is part of your plan, that’s the first calendar entry, not the last.
Huts, campsites, and the May booking trap
Four huts and one campsite serve the Routeburn during the Great Walks season. Bookings are per bunk, per night, on DOC’s Great Walks booking system, and a booking for the full crossing means booking every night separately, in the right huts, before anyone else takes them.
| Hut / campsite | Side | Typical position on the walk |
|---|---|---|
| Routeburn Flats Hut & Campsite | Glenorchy side | End of a short first day, or a base for day 1 |
| Routeburn Falls Hut | Glenorchy side | Below the Harris Saddle, most common night 1 |
| Lake Mackenzie Hut | Fiordland side | After crossing Harris Saddle, most common night 2 |
| Lake Howden Hut | Fiordland side | Near the Divide, used for a shorter final day or the Key Summit turn-off |
Booking timeline that actually matters:
| When | What happens |
|---|---|
| May | DOC opens bookings for the season starting in late October |
| First hours after opening | Peak-season bunks (December to February) routinely sell out |
| June–September | Off-peak nights and cancellations still findable, shoulder months easier |
| October–April | Great Walks season: huts staffed, track maintained, campsite open |
| Outside October–April | Huts unserviced, no warden, alpine conditions on Harris Saddle |
If you’re planning this trip more than a season out, treat May as the real deadline, not “sometime before the trip.” Guided, fully catered walks run by private operators use separate allocations and their own booking calendars, which is one reason people who miss the DOC window still end up on the track.
When to walk it
The Great Walks season runs late October to April, which is also, practically, the only season most visitors should consider. Inside it, huts have wardens, gas cookers, and a maintained track; the Harris Saddle, the highest point of the crossing, is normally clear of snow by December and stays open into autumn. December to February is busiest and warmest; March and April bring smaller numbers, cooler mornings and (in a good year) clearer air for the saddle views.
Outside that window the huts revert to basic, unheated shelters with no warden and no bookings required — but also no track upgrades, and the saddle section becomes a genuine alpine crossing with snow, ice and avalanche terrain. That’s a trip for experienced, well-equipped trampers checking DOC’s current avalanche and track advisories, not a shoulder-season extension of the Great Walk. If your window only allows a winter attempt, the honest advice is to walk Key Summit instead and save the full crossing for October to April.
Key Summit: the Routeburn in a single day
Key Summit is a loop track that branches off the Routeburn near Lake Howden, close to the Divide end. It climbs through beech forest to an open alpine basin with tarns and views across three valley systems — the Hollyford, the Eglinton and the Greenstone — without needing a hut booking or an overnight stay. Return time from the Divide car park is around 3 to 4 hours.
It’s the practical way to experience the character of the Routeburn — the same alpine basin-and-tarn landscape, the same beech-to-tussock transition — without committing 2 to 4 days and a hut booking to it. Because the Divide sits on the Milford Road, Key Summit is usually combined with a Milford Road trip rather than driven to on its own; see the day walks in Fiordland guide for how it fits alongside other short walks on that road.
Getting to both ends
This is a one-way track, and the two ends are roughly 300km apart by road via Te Anau — not a walk back to your car. Sort transport before you sort anything else about the itinerary.
- Routeburn Shelter (Glenorchy side): about 1 hour from Queenstown by road via Glenorchy and Paradise, on a route described in the car rental and buses and shuttles guides.
- The Divide (Fiordland side): on the Milford Road, about 1 hour 40 from Te Anau and roughly 4 hours from Queenstown by road — most people reach it from the Te Anau side rather than driving the long way from Queenstown.
Because the ends are so far apart by road, almost nobody drives their own car for a one-way crossing. The usual pattern is a shuttle booking that drops you at one end and either collects you at the other or connects with a second shuttle from the Divide back through Te Anau. Build that shuttle booking into the same planning session as your hut booking — shuttle seats for peak Routeburn dates fill up alongside the huts, not after them.
What’s on the track, day by day
A typical three-day itinerary from the Routeburn Shelter:
- Day 1 — Routeburn Shelter to Routeburn Falls Hut: beech forest along the Route Burn, climbing gradually to the open flats and then a steeper final push to the Falls hut, roughly 5 to 6 hours.
- Day 2 — Routeburn Falls to Lake Mackenzie Hut: the highlight day, over the Harris Saddle (weather permitting, with views back toward the Darran Mountains) and down through alpine tussock to Lake Mackenzie, roughly 6 to 7 hours.
- Day 3 — Lake Mackenzie to the Divide: forest walking past Lake Howden and the Key Summit junction, finishing at the road end, roughly 4 to 5 hours, with the option to add the Key Summit loop on the way out if energy and weather allow.
A 4-day version simply splits one of these into two shorter days, commonly using Routeburn Flats as a gentler first night for parties with children or less tramping experience.
Guided options and what else fills the Routeburn Valley
For visitors without 2 to 4 spare days, guided operators run fully catered Routeburn walks with their own hut network, and separately, day tours from Queenstown reach the Routeburn Valley for activities that don’t require walking the full Great Walk at all. A full day canyoning trip descending waterfalls and gorges in the Routeburn Valley is one way to spend a day in the same valley system without booking a Great Walks hut.
Scenic flights are the other common substitute for people short on time. A helicopter tour and scenic cruise departing Glenorchy crosses over the ranges the Routeburn climbs on foot, and a 35-minute alpine helicopter flight with a glacier landing covers a wider loop of the surrounding mountains for those who want the view without the days of walking.
Near the Divide end, Te Anau makes a natural stop before or after a crossing, and it’s common to add a boat and cave tour to the Te Anau glowworm caves on the evening you come off the track. Anyone deciding between guided and independent walking, or between the Routeburn and its neighbours, should read the dedicated Routeburn Track guide and the wider roundup of Great Walks near Queenstown before booking.
What to budget
| Item | Typical cost (NZD) |
|---|---|
| DOC Great Walks hut, per person per night (peak season) | $80–90 |
| DOC Great Walks campsite, per person per night | $25–30 |
| One-way shuttle between the two ends | $90–150 per person |
| Guided, fully catered 3-day walk | $1,600–2,200 per person |
| Key Summit as a self-guided day walk | Free beyond getting to the Divide |
The gap between the DOC price and a guided walk is large, and it buys a warm bed, cooked meals and a local guide rather than a cheaper version of the same track — most independent trampers carrying their own food and sleeping bag land closer to the hut and shuttle figures above.
Fitness, gear and weather
The Routeburn is graded as a Great Walk — a well-formed, benched track suitable for people with reasonable tramping fitness — but it still crosses an exposed alpine saddle above 1,200 metres, and Fiordland weather changes fast. Pack for rain and wind regardless of the forecast, carry a map or the DOC app even on a maintained track, and check current track and weather advisories before setting out, especially for the Harris Saddle section.
This is one crossing among several worth comparing before you commit a booking window to it; the best hikes around Queenstown guide and the broader hiking and walks category set the Routeburn against shorter day walks and against the neighbouring Milford Track and Greenstone and Dart River routes, for anyone still choosing between them.
Routeburn Track: frequently asked questions
When do Routeburn Track hut bookings open?
DOC opens bookings for the following Great Walks season in May, and Routeburn bunks for the popular months routinely sell out within hours. If you know your dates, book the moment the season opens rather than waiting until spring.
Do I need to book a campsite as well as huts?
Yes. Routeburn Flats has a campsite as an alternative to the hut there, but it runs on the same Great Walks booking system with its own limited numbers, not a first-come basis.
Can I walk the Routeburn Track outside the Great Walks season?
Yes, but huts become unserviced (no warden, no gas cookers, no track upgrades) and conditions turn genuinely alpine, with snow, ice and avalanche paths on the Harris Saddle section. This is for experienced, well-equipped trampers only, and current DOC track and weather advisories should be checked before setting out.
How difficult is the Routeburn Track?
It is graded a Great Walk, meaning a well-formed track suitable for people with some tramping fitness, but it still crosses an alpine saddle above 1,200 metres with real weather exposure. It is harder than a day walk and easier than off-track alpine routes.
What is Key Summit and do I need to book anything for it?
Key Summit is a loop off the Routeburn near the Divide, walkable in 3 to 4 hours return without booking a hut, since it doesn’t require an overnight stay on the Great Walk itself.
Do I need transport at both ends, or is it a loop?
It’s a one-way crossing, not a loop. The Routeburn Shelter end near Glenorchy and the Divide end on the Milford Road are roughly 300km apart by road, so most trampers use a shuttle service that links the two rather than a rental car.
Can I experience the Routeburn Track in a single day from Queenstown?
Yes, guided day walks cover the Key Summit section from the Divide, and scenic flights over the wider Routeburn-Fiordland landscape are sold separately as an alternative for those without the days for the full crossing.
