10 Best Day Hikes in Fiordland National Park

Fiordland National Park has been calling adventurers from all over the world since it was established back in 1952. Today it covers more than 1.2 million hectares (that's nearly 3 million acres) of the wildest country in New Zealand. It was declared a World Heritage Area in 1986, and now forms the heart of Te Wāhipounamu (the place of pounamu, or greenstone), the South West New Zealand World Heritage Area. Fourteen fiords (yes, we spell it "fiord" down here), hundreds of lakes, snow-capped granite peaks and ancient beech forest - when it comes to hiking in Fiordland National Park, you're spoilt rotten. And here's the best bit: you don't need to shoulder a heavy pack for days to experience the very best of it.

So, what are the best day hikes in Fiordland National Park? We've spent years wandering this corner of the South Island with our guests, and below you'll find our ten favourites - from ten-minute leg-stretchers to proper alpine days out - each with the distance, time and difficulty so you can plan your perfect day.

Fiordland Day Hikes at a Glance

Mirror Lakes - 10 minutes

Let's start small. About halfway along the Milford Road from Te Anau you'll find the Mirror Lakes, a chain of little lakes tucked beneath the Earl Mountains. A short boardwalk takes you along the water's edge, and on a calm day, the reflections of the peaks above are so perfect you'll wonder which way is up.

Lake Gunn Nature Walk - 45 minutes

A little further up the road at the Cascade Creek carpark, this gentle 45-minute, 1.4km (0.9 mile) loop wanders through some of the oldest and most beautiful red beech forest in the park. The moss here grows thick enough to sink your hand into, and the birdlife is wonderful - listen for the chatter of pīwakawaka (fantails) following you along the track. It's an easy, mostly flat wander and a lovely way to stretch the legs on the drive to Milford Sound.

Milford Foreshore Walk - 30 minutes

If you've come all the way to Milford Sound/Piopiotahi, don't just hop off the boat and back on the bus. The foreshore walk along the water's edge gives you the classic postcard view of Mitre Peak rising straight out of the sea, no cruise ticket required. Interpretation panels along the way tell the story of the fiord, which Māori legend says was carved by the demigod Tuterakiwhanoa from formless rock. Looking up at those sheer walls, it's easy to believe. One word of friendly advice: bring insect repellent, because the famous Fiordland sandflies consider the foreshore their dining room.

Humboldt Falls - 30 minutes

Down the unsealed Hollyford Road (take it slowly - it's gravel most of the way) a short, well-formed track climbs gently for 1.2km (0.7 miles) return to a viewing platform facing the Humboldt Falls, among the highest waterfalls in New Zealand. The falls tumble some 275 metres (900ft) in three great leaps down the far wall of the valley, and after heavy rain (which Fiordland does rather well) they are nothing short of spectacular.

Key Summit – 3-hour return

This is the one we recommend most often, and the day hike we return to again and again on our own guided trips. Starting from The Divide carpark on the Milford Road, you'll follow the famous Routeburn Track - one of New Zealand's 11 Great Walks - for about an hour before turning off for the 20 to 30 minute climb to Key Summit. It's 3.4km (2.1 miles) each way, and up top a wee alpine nature walk loops past tarns and bogs with panoramic views over the Humboldt and Darran Mountains. Forest, wetland, alpine gardens and big mountain views, all in a morning - it's Fiordland in miniature.

Enjoy the spectacular views from Key Summit.

Lake Marian - 3 hours return

Turn off the Milford Road at Marian Corner, about 87km (54 miles) from Te Anau, and follow the Hollyford Road for 1km (0.6 miles) to the carpark. The track crosses a swing bridge and passes a spectacular series of waterfalls within the first ten minutes - if you're short on time, the falls alone are worth the stop. Beyond them, the track turns steep, rooty and often muddy as it climbs for around an hour and a half to the lake itself.

And what a lake it is. Lake Marian sits in a hanging valley gouged out by ancient glaciers, ringed by the peaks of the Darran Mountains, and on a still day the reflections are something else. It's a genuine tramping track (tramping is what we Kiwis call hiking), so sturdy boots and a reasonable level of fitness are essential. Keep an eye out for ongaonga (native stinging nettle) beside the track - look, don't touch.

Rainbow Reach to Moturau Hut - 3 to 4 hours return

Our favourite gentle taste of the Kepler Track. From the Rainbow Reach carpark, 12km (7.5 miles) from Te Anau, cross the swing bridge and wander through mossy beech forest and across wetland boardwalks beside the Waiau River - film buffs might recognise the river, which starred as the River Anduin in The Lord of the Rings. After around 6km (3.7 miles) the forest opens out to the wide blue sweep of Lake Manapouri and the beachside Moturau Hut, which might just be the best picnic-lunch spot in the park. We love this walk so much we've included sections of the Kepler in our Masterpiece trip.

Brod Bay to Te Anau - 3 to 4 hours

Fancy a boat ride with your walk? Hop on a water taxi across Lake Te Anau - the largest body of fresh water in Australasia, by the way - to Brod Bay, then follow the Kepler Track back along the lakeshore through quiet, mossy beech forest. It's about 5.6km (3.5 miles) of easy walking to the track's start near the control gates, then a pleasant 50-minute lakefront stroll into town. Call into Punanga Manu o Te Anau, the lakeside bird sanctuary, on your way - it's one of the few places anywhere you can see takahē, a flightless bird once thought extinct.

Soak up the views across Lake Te Anau.

Luxmore Hut - a full day (or a helicopter)

Here's the honest truth: walking from Te Anau up to Luxmore Hut and back is a very big day - the climb from Brod Bay alone takes 3 hr 30 min to 4 hr 30 min each way, under limestone bluffs and up through the beech forest to the tussock tops. Most people trim the day by taking the morning water taxi to Brod Bay, and it's still a solid 8 hours or more. The reward? One of the great views in Fiordland, out across the Te Anau basin to the Murchison Mountains. You've earned it!

If that sounds like more sweat than holiday, there's a more opulent way to do it. On our New Zealand Great Walk Adventure - South, a helicopter lifts you over the hidden lakes and beech forest of Mt Luxmore and sets you down by the hut, so you can walk the best of the Kepler downhill to Brod Bay and cruise back across the lake to Te Anau. No heavy pack, no relentless climb, no early alarm - just the good bits. It's a guest favourite for a reason.

Gertrude Saddle - experienced hikers only

We'd be telling fibs if we left Gertrude Saddle off a list of Fiordland's best day hikes - the view from the saddle down the Gertrude Valley to Milford Sound/Piopiotahi is one of the finest in the country. But we'd also be doing you a disservice if we didn't give it to you straight: this is an expert-grade alpine route, not a walk. Above the valley floor there are no permanent track markers, the route climbs steep granite slabs (with steel cables to assist), and the Department of Conservation's advice is blunt: if there's rain or snow, don't go. Allow 4 to 6 hours return from the Gertrude Valley carpark, carry a personal locator beacon, and only attempt it in good, dry conditions if you have genuine alpine experience. For everyone else, Key Summit delivers world-class views at a fraction of the risk.

When is the best time to hike in Fiordland?

Our summer, December to February, brings the longest days and the most settled weather, and the shoulder months of October, November, March and April are quieter and often lovely. Winter (June to August) turns the high country serious - snow, ice and avalanche risk close in on the alpine routes, though the short lakeside and valley walks remain wonderful year-round. For the full picture, have a read of our guide to the best time for hiking in New Zealand.

How to explore Fiordland on a guided trip

Could you rent a car and tick off these walks yourself? Absolutely. But there's something special about exploring Fiordland with a local who knows where the trail quietens down, which lookout to save for lunch, and what that birdsong overhead actually is. Two of our trips spend generous time here: the Masterpiece, our flagship South Island journey that includes a Kepler Track walk and a Milford Sound cruise, and the New Zealand Great Walk Adventure - South, five days sampling the finest day walks on the Kepler, Milford, Routeburn and Rakiura tracks (helicopter included). Everything is taken care of - accommodation, meals, transport and Kiwi guides who love this place like their own backyard. Because it is.

And if a multi-day walk is calling your name, Fiordland is home to some of New Zealand's most famous Great Walks, including the Milford, Kepler and Routeburn tracks; our guide to hiking the Milford Track with a guide is a good place to start dreaming.

Top tips for hiking in Fiordland National Park

Be prepared for all weather. Fiordland is one of the wettest places in New Zealand - parts of the park receive up to 9 metres (nearly 30ft) of rain a year - and alpine conditions can change in minutes. Pack proper waterproofs and warm layers, whatever the forecast says.

Wear the right footwear. The short walks are well-formed, but tracks like Lake Marian and Luxmore demand sturdy, broken-in hiking boots and decent socks. Happy feet, happy hiker.

Carry water and snacks. These are wilderness areas and facilities are few and far between. Bring more scroggin (trail mix) than you think you'll need.

Tell someone your plans. Let someone know where you're going and when you'll be back, and consider carrying a personal locator beacon (PLB) for the longer tracks - they can be hired in Te Anau. The Fiordland National Park Visitor Centre on Lakefront Drive is the place for up-to-date track conditions.

Check before you go. The Department of Conservation (DOC) website and the NIWA Fiordland forecast are your friends. Five minutes of checking beats a soggy surprise.

Fiordland day hikes FAQ

How many days should I spend in Fiordland?

Give it two to three days if you can. That's enough for a Milford Road day (Key Summit plus the short stops), a Kepler day out of Te Anau, and a cruise on Milford Sound/Piopiotahi. You could easily fill a week - plenty of our guests wish they had. And if you're weighing up where Fiordland fits in a bigger itinerary, our guide to New Zealand's best national parks is a handy place to compare notes.

What's the best Fiordland day hike for non-experts?

Key Summit, hands down. It's a well-formed track the whole way, three hours return, and you won't find a bigger view for less puff anywhere in the park. Mirror Lakes and Lake Gunn are perfect if you'd rather amble than climb.

Is Milford Sound worth visiting?

Absolutely! Famously dubbed the eighth wonder of the world, it more than lives up to the hype - and the drive in along the Milford Road, with its walks and waterfalls, is half the joy. Allow a full day from Te Anau and don't rush it.

Do I need a guide to hike in Fiordland?

For the walks on this list (Gertrude Saddle aside), no - they're well-marked and manageable independently. What a guide adds is everything else: the stories, the safety net, the logistics, and the local knowledge that turns a nice walk into the best day of your trip.
