The best hikes in New Zealand's Southern Alps are the 32 km Routeburn Track linking Mount Aspiring and Fiordland National Parks over the 1,255 m Harris Saddle, the alpine Gertrude Saddle day walk, and the high passes around Aoraki/Mount Cook. These South Island trails cross glaciated valleys and beech forest and walk best in the Great Walk season from late October to April 2026, when huts are staffed and passes are snow-free.
The Southern Alps run the length of New Zealand's South Island, throwing up the country's most dramatic alpine hiking: hanging valleys, turquoise tarns and saddles with views over Fiordland to the Tasman Sea. Some of the world's great multi-day tramps sit here, alongside punchy day walks. This guide ranks the routes worth planning a trip around in 2026, with distances, seasons and links to full trail data.
What is the best multi-day hike in the Southern Alps?
The Routeburn Track is the standout alpine traverse, a 32 km point-to-point tramp crossing the 1,255 m Harris Saddle between Mount Aspiring and Fiordland National Parks over two to four days. It is one of New Zealand's ten Great Walks, with views from Conical Hill (1,515 m) stretching to the Hollyford Valley and the Darran Mountains. The full stage breakdown, hut details and GPX download are on our Routeburn Track route guide. Huts must be booked in advance for the Great Walk season — they sell out within hours of opening.
Which Southern Alps hike is best for solitude?
For a quieter alternative still within reach of the alpine zone, the Heaphy Track offers 78.4 km of varied terrain across Kahurangi National Park, New Zealand's longest Great Walk, descending from tussock downs to nikau-palm coast. It sits at the northern end of the alpine spine and sees fewer crowds than the Routeburn. Compare them in our Routeburn vs Heaphy comparison, and explore the full route on our Heaphy Track guide.
Southern Alps trails compared
| Trail | Distance | Days | Highlight |
|---|---|---|---|
| Routeburn Track | 32 km | 2–4 | Harris Saddle 1,255 m |
| Heaphy Track | 78.4 km | 4–6 | Tussock to coast |
| Rakiura Track | 32 km | 3 | Stewart Island coast |
When is the best time to hike the Southern Alps?
The Great Walk season runs from late October to the end of April, when huts are fully serviced, bridges are in place and the alpine passes are usually clear of snow. January and February are the warmest and busiest, with daytime valley temperatures around 15–22 °C; late October to early December and March to April offer quieter trails and stable weather. Outside this window the same routes become serious alpine undertakings with avalanche risk and unbridged rivers. The Department of Conservation publishes current alerts on the DOC official site.
What gear do you need for alpine tramping?
Southern Alps weather changes fast, so carry full waterproofs and warm layers even in summer. A 50–65 L pack handles a multi-day hut trip with food and a sleeping bag: the ventilated Osprey Atmos AG 65 and women's Osprey Aura AG 65 are popular, while the comfortable Deuter Aircontact Core 50+10 carries heavier loads on the longer Heaphy. Lighter, faster trampers favour the Zpacks Arc Blast 55L. Our Routeburn packing list covers the full kit.
Booking and access for 2026
Great Walk hut bookings for the 2026–27 season open months in advance through the Department of Conservation and sell out fast for the Routeburn — set a reminder for the booking date with the Department of Conservation. Transport details and current alpine forecasts for the region are published by MetService. Most trampers base in Queenstown or Te Anau for the Routeburn, with shuttle transfers linking the two trailheads. Plan timing around the late-October-to-April window detailed in our best time to hike the Routeburn guide.
How do you reach the Southern Alps trailheads?
Most Southern Alps tramps are organised from Queenstown or Te Anau, both well connected to the rest of New Zealand. Queenstown Airport receives direct flights from Auckland, Christchurch and Wellington, and sits about a 45-minute drive from the Routeburn's Glenorchy trailhead. The Routeburn is a point-to-point traverse, so you cannot simply return to your car, which makes transport planning essential.
For the Routeburn, shuttle services link Queenstown and Te Anau to both the Routeburn Shelter (Glenorchy) and The Divide trailheads, with a typical one-way shuttle costing around NZD 50-90; many trampers book a package that drops them at one end and collects them from the other. The longer Heaphy Track is more remote, reached from Golden Bay near Collingwood at its eastern end or from Karamea on the West Coast at its western end, with a long road transfer or a short charter flight between the two ends. Plan transfers when you book your huts, since both fill in the Great Walk season. Base yourself in Queenstown for the Routeburn and surrounding alpine day walks like Gertrude Saddle, or in Te Anau if you also plan to tackle the Milford or Kepler Tracks. Hire cars are widely available but pricey in summer, so book early. Whichever trailhead you target, allow a buffer day for the long, winding South Island drives and for Fiordland weather, which can delay flights and roads alike in 2026.
Timing a wider South Island hiking trip in 2026 around the Great Walk season opens up the chance to combine several routes. Many trampers base in Queenstown and Te Anau and string together the Routeburn with the nearby Kepler or Milford Tracks, or add alpine day walks like Gertrude Saddle and Roys Peak for big views with no hut booking required. Further north, the Heaphy pairs naturally with the Abel Tasman Coast Track for a contrast of rugged interior and golden coast. The driving distances are real, so allow buffer days for the winding South Island roads and for weather that can close mountain passes. Booking huts the moment the season opens, then planning your transport and day walks around those fixed dates, is the most reliable way to assemble a multi-trail Southern Alps adventure.
Frequently Asked Questions
What is the most famous hike in the Southern Alps?
The Routeburn Track is the most famous multi-day hike in the Southern Alps, a 32 km Great Walk crossing the 1,255 m Harris Saddle between Mount Aspiring and Fiordland National Parks. Its accessibility from Queenstown and its alpine scenery make it one of New Zealand's most booked tramps.
Do you need to book huts on Southern Alps Great Walks?
Yes. During the Great Walk season (late October to April), huts on the Routeburn, Heaphy and other Great Walks must be booked in advance through the Department of Conservation, and the Routeburn often sells out within hours of bookings opening for the season.
When does the Great Walk season start in New Zealand?
The Great Walk season typically runs from late October to the end of April, when huts are fully serviced and alpine passes are usually snow-free. Exact dates vary slightly by track each year, so check the Department of Conservation site for the 2026–27 season before booking.
Are the Southern Alps hikes suitable for beginners?
Several are, within the Great Walk season. The Routeburn and Rakiura Tracks have well-graded paths and serviced huts that suit fit beginners, though alpine weather can change fast. Outside the season, these same routes become advanced undertakings requiring river-crossing and avalanche awareness.
How changeable is the weather in the Southern Alps?
Very. Fiordland is one of the wettest places on Earth, receiving several metres of rain a year, and conditions on alpine passes can shift from sun to storm within hours. Carry full waterproofs and warm layers even in midsummer, and check the MetService forecast before each day.
