The Best Hikes on New Zealand’s South Island
Fiordland’s Great Walks, the glacial valleys of Aoraki/Mount Cook, and the ridgeline viewpoints above Wanaka – the South Island packs more world-class hiking into one island than almost anywhere on Earth. Here’s how to choose and plan yours.
The South Island is New Zealand’s hiking heartland – six of the country’s Great Walks and a deep bench of iconic day hikes, all within a compact island. If you have a few days and can book ahead, a Great Walk (Milford, Routeburn, Kepler) is the headline experience. If you’re road-tripping, string together day hikes – the Hooker Valley, Roys Peak, Mueller Hut – between towns.
The single most important planning fact: the popular Great Walks book out fast through DOC, sometimes within minutes. Decide early, be flexible on dates, and keep backup tracks in mind. Below, everything is organized by type (Great Walks vs day hikes) and by region so you can build a realistic itinerary.

Why the South Island is a hiker’s island
Compact, uncrowded by global standards, and impossibly varied.
New Zealand’s South Island runs a 500-kilometre spine of glaciated mountains – the Southern Alps – down its western side, and the tracks that thread through them are among the best-built and best-scened in the world. In a single island you can walk a rainforest valley to a fiord, cross an alpine pass under 3,000-metre peaks, trace a golden-sand coastline, and stand on a ridge above a turquoise glacial lake. New Zealand’s Department of Conservation (DOC) maintains a network of huts and graded tracks that make multi-day wilderness hiking truly accessible, while the country’s small population means even the famous routes feel wild.
The catch is the weather. The South Island’s maritime climate changes fast, and the western ranges – especially Fiordland – are among the wettest places on Earth. That rain is what makes the waterfalls thunder and the moss glow, but it means every hiker here plans around wet-weather gear and flexible timing. Get the season and the booking right, respect the weather, and the South Island delivers hiking that’s hard to match anywhere.
The Great Walks
Six of New Zealand’s premier multi-day tracks are on the South Island. Book these early.
1. Milford Track
FiordlandLong billed as “the finest walk in the world,” the Milford runs one-way from the head of Lake Te Anau through the Clinton and Arthur valleys to Milford Sound, crossing Mackinnon Pass (1,154 m) with its alpine views and passing Sutherland Falls, one of New Zealand’s tallest. It’s a rainforest-and-waterfall classic – and the most booking-sensitive track in the country, walked one-way on fixed dates, so huts sell out fast. Independent walkers use DOC huts; guided walkers use separate private lodges.
2. Routeburn Track
Fiordland / Mt AspiringThe most scenic-per-kilometre of the Great Walks – a shorter alpine traverse linking Mount Aspiring National Park and Fiordland, crossing Harris Saddle (1,255 m) with open views across the Humboldt Mountains and past the alpine tarn of Lake Harris. Its brevity and beauty make it the most popular choice for hikers short on time, and it pairs naturally with the neighbouring Greenstone or Caples tracks for a longer loop.
3. Kepler Track
FiordlandA purpose-built loop from near Te Anau that climbs to exposed alpine ridges – the stretch to and beyond Luxmore Hut is one of the finest ridge walks in the country – before descending through beech forest along Lakes Te Anau and Manapouri. Because it starts and ends near town and forms a loop, the Kepler is the best-value alternative to the Milford when Milford dates are gone, with comparable alpine scenery and easier logistics.
4. Abel Tasman Coast Track
NelsonThe easiest and sunniest Great Walk – a gentle coastal route along golden beaches, forested headlands, and turquoise bays in the northwest corner of the South Island. Water taxis let you shorten it, skip sections, or day-hike the best parts, which makes it ideal for families and first-time multi-day hikers. Tide timing matters at a couple of estuary crossings; otherwise it’s the region’s most relaxed multi-day walk.
5. Heaphy Track
KahurangiThe longest of the South Island Great Walks and the most ecologically varied – crossing Kahurangi National Park from tussock downs and beech forest to a wild West Coast of nikau palms and roaring surf. It’s a big, remote traverse with a real sense of journey, and (uniquely) it’s open to mountain bikes in winter. Longer and more committing than the alpine Fiordland tracks, but non-technical throughout.
6. Paparoa Track
West CoastNew Zealand’s newest Great Walk (opened 2019), crossing the Paparoa Range on the West Coast with limestone karst, river gorges, and alpine tops, built partly as a memorial to the 29 men lost in the 2010 Pike River mine tragedy. It’s a dual walking-and-mountain-biking track, and it pairs well with a visit to the nearby Pancake Rocks at Punakaiki. A strong, quieter alternative to the Fiordland classics.
Iconic day hikes
Big scenery without the multi-day commitment — perfect for a road trip.
Hooker Valley Track
~10 km return · flat. The South Island’s most beloved easy walk — three swing bridges up a glacial valley to a lake beneath Aoraki. Note: partly closed in 2026 for a bridge rebuild (open only to the Mount Sefton lookout); check DOC for current status.
Roys Peak Track
16 km return · ~1,300 m gain. The most-photographed viewpoint in New Zealand — a relentless but non-technical climb to a ridgeline high above Lake Wanaka. Start early to beat crowds and heat; there’s no shade.
Mueller Hut Route
10.4 km return · ~1,000 m gain. A steep alpine climb past the Sealy Tarns “stairway to heaven” to a red hut ringed by glaciers and hanging ice — one of the best hut views in the country. Real mountain terrain; can hold snow.
Rob Roy Glacier Track
~10 km return. A rewarding valley walk in Mount Aspiring National Park to a viewpoint beneath a hanging glacier, with waterfalls and (often) kea. A gravel road drive from Wanaka reaches the trailhead.
Ben Lomond Track
~11 km return from the gondola top. A big climb to a 1,748 m summit with panoramic views over Queenstown and Lake Wakatipu. The Skyline Gondola cuts the first climb; the summit ridge is exposed.
Key Summit (Routeburn)
~7 km return. A day-hike taste of the Routeburn from the Divide — climbing to an alpine wetland with a nature walk and views into the Hollyford and Greenstone valleys. The best short alpine walk on the Milford Road.
Hikes by region
How the South Island’s hiking areas fit together for an itinerary.
Fiordland
The wettest, wildest, most dramatic corner of the country and home to three Great Walks (Milford, Routeburn, Kepler) plus superb day hikes (Key Summit, Gertrude Saddle) off the Milford Road. Base in Te Anau. Expect rain, waterfalls, fiords, and sandflies. This is the region most hikers build a South Island trip around.
Aoraki / Mount Cook
New Zealand’s highest peaks ring a compact national park of moraine valleys and glacial lakes. The valley walks (Hooker Valley, Tasman Lake) are gentle; Mueller Hut and Sealy Tarns are steep alpine classics. The peak itself, Aoraki/Mount Cook (3,724 m), is a serious technical climb — but you don’t need to climb it to walk beneath it.
Wanaka & Queenstown
The adventure-town heart of the South Island. Wanaka gives you Roys Peak, Rob Roy Glacier, and access to the Matukituki Valley beneath Mount Aspiring/Tititea; Queenstown gives you Ben Lomond and the Routeburn trailheads. Easy to combine day hikes with the Fiordland Great Walks in one loop.
Nelson & the Top of the South
Sunnier and gentler, with two Great Walks: the coastal Abel Tasman and the long, wild Heaphy. This is the region for beach hiking, families, and first-time multi-day walkers, and it makes a natural start or finish for a north-to-south island traverse.
The West Coast
Wild, wet, and thinly populated, with the newest Great Walk (Paparoa), the glaciers at Franz Josef and Fox, and the Pancake Rocks at Punakaiki. Often driven through between Nelson and the south — but worth its own days for hikers who like solitude and dramatic coast.
Booking & huts
The part that trips up first-time visitors — sort it early.
Great Walk huts and campsites are booked through the Department of Conservation (DOC) online booking system. Bookings for the summer Great Walks season open months in advance, and the marquee tracks — Milford and Routeburn above all — sell out for peak dates within minutes to hours. Every night on a Great Walk requires a pre-booked ticket for a specific hut or campsite; you can’t simply turn up and walk. If your dates are fixed, book the moment the season opens; if they’re flexible, you’ll have far more luck. Keep the Kepler and Heaphy in your back pocket as excellent, less-frantic alternatives.
Beyond the Great Walks, the wider backcountry uses a hut ticket / Backcountry Hut Pass system for hundreds of standard huts, most of which are first-come, first-served. Day hikes need no booking at all. The one thing worth building your trip around is securing a Great Walk if you want one — everything else can be planned loosely.
| Great Walk | Distance | Days | Region | Best for |
|---|---|---|---|---|
| Milford | 53.5 km | 4 | Fiordland | The bucket-list classic |
| Routeburn | 32 km | 2–3 | Fiordland / Aspiring | Best alpine scenery, short |
| Kepler | 60 km | 3–4 | Fiordland | Best-value Milford alternative |
| Abel Tasman | 60 km | 3–5 | Nelson | Easiest; families |
| Heaphy | 78.4 km | 4–6 | Kahurangi | Most varied; remote |
| Paparoa | 55 km | 3 | West Coast | Newest; walk or bike |
When to go
The Southern Hemisphere flips the calendar — summer is December to February.
November to April is the main hiking season, matching the serviced Great Walks season. December to February brings the longest days and warmest weather — and the biggest crowds and hardest bookings. March and early April are a sweet spot: still-good conditions, thinner crowds, easier huts. Outside the Great Walks season the same tracks drop to full backcountry standard — bridges may be removed, huts unserviced, avalanche risk real on the alpine sections — so May to October hiking is for experienced parties with winter skills. Whatever the month, New Zealand’s weather changes fast; plan buffer days and never bank on a forecast holding.
What to know before you go
The handful of things every first-time South Island hiker should plan around.
Weather & rain. The west is wet — Milford Sound averages over 6 metres of rain a year. Bring proper waterproofs and be ready to hike in rain; that’s when the waterfalls are best. Sandflies. Fiordland’s tiny biting sandflies swarm at trailheads, huts, and the coast — carry strong repellent and cover up at dawn and dusk. Kea. The cheeky alpine parrot will investigate (and chew) unattended gear; don’t leave boots or packs open at alpine huts. River crossings & alpine sections. Some routes cross unbridged streams that flood in rain — if in doubt, wait it out. Leave your plans behind. Tell someone your route and return time, and consider a personal locator beacon (rentable in most gateway towns) for remote or alpine walks.
Frequently asked questions
What is the best hike on the South Island?
For multi-day, the Milford Track (53.5 km) is the famous choice, with the Routeburn best for alpine scenery and the Kepler the best-value alternative. For a single day, the Hooker Valley (check its closure status) and Roys Peak are the icons. It depends on whether you want a Great Walk or a big day out.
How do you book the Great Walks?
Through DOC’s online booking system. Bookings open months ahead and Milford/Routeburn sell out within minutes to hours for peak dates. Every hut night needs a pre-booked ticket — you can’t just turn up. Book early, be flexible, and keep Kepler and Heaphy as backups.
When is the best time to hike?
November–April (the Great Walks season). December–February is warmest but busiest; March–early April is quieter with good conditions. Winter hiking (May–October) needs real backcountry and alpine experience, as tracks drop to unserviced standard.
Which Great Walk is easiest?
The Abel Tasman Coast Track — a gentle coastal route with water-taxi access, ideal for families and beginners. The Heaphy is longer but mostly non-alpine. The Fiordland tracks are moderate, with alpine passes and weather exposure.
Is the Hooker Valley Track open?
As of 2026 it’s partly closed — open only to the Mount Sefton lookout while a swing bridge is rebuilt, with full reopening expected around autumn 2026. Check the DOC Aoraki/Mount Cook page for current status; Sealy Tarns and Mueller Hut are nearby alternatives.
Do I need a guide?
No — the Great Walks and popular day hikes are designed for independent walkers with proper gear and hut bookings. Guided options exist (including on Milford) but aren’t required. You do need waterproofs, warm layers, sturdy boots, and the judgment to wait out weather.
What about sandflies and Fiordland weather?
Fiordland is extremely wet (6+ metres of rain a year at Milford Sound) and famous for biting sandflies. Bring real waterproofs and strong repellent, cover up at dawn and dusk, and treat the rain as part of the experience — it’s what makes the waterfalls spectacular.
Sources & methodology
Track distances, durations, grades, and hut logistics are compiled from the New Zealand Department of Conservation (DOC), which administers the Great Walks and the wider hut network, and cross-checked against national park sources. Where a track’s official distance varies between sources, we use the DOC figure. Season windows and booking behaviour reflect recent Great Walks seasons.
Distances are in kilometres and elevations in metres, following New Zealand convention. Track closures, bridge works, booking rules, and season dates change every year — the Hooker Valley closure noted here is one live example — so always confirm current status with DOC before building a trip around a specific track.
