The Milford Road

Why it matters

There is a gap in the published information about this road, and it is a strange one. The Department of Conservation does not publish a stop-by-stop itinerary for it. Its area page gives you the driving time, the distance and a set of warnings, and does not list the Eglinton Valley, Knobs Flat, the Mirror Lakes, Lake Gunn, Monkey Creek or Pop's View as places you might get out of the car. The regional tourism body's list is the nearest thing that exists, it carries no date, and it is wrong about the Chasm.

So most visitors arrive with a boat time and no plan, and the road becomes transit. It is not transit. It is one of only a handful of roads that penetrate Fiordland at all — everything west of it is roadless, and much of that is formal wilderness where even landing an aircraft is prohibited. The valley it runs up is a mainland conservation stronghold under intensive predator control, and DOC puts up to seven hundred thousand people a year through it.

This page is about the road as a place. The practical business of driving it — the Homer Tunnel, the closure days, chains between June and November, the absence of fuel and phone signal, and where to check conditions on the morning — belongs to our Milford Sound page, and we are not repeating it here.

What it's like

The road changes character three times and the changes are abrupt enough to notice. For the first forty minutes it runs along the lake through farmland, ordinary and pleasant, and then at Te Anau Downs it turns inland and the beech closes over. What follows is the Eglinton — a wide flat-bottomed glacial valley with golden tussock on the floor and red beech going straight up the walls on both sides, and a road running dead straight through the middle of it. It does not look like the rest of New Zealand. It looks like somewhere the ice left twenty minutes ago and the grass moved in.

Then it climbs. The beech thins, the tussock gives out, and you come into the upper valley under the Darran Mountains with waterfalls coming off rock that is close enough to feel overhead. This is the stretch where the weather makes the decisions, and where the drive stops being pretty and starts being alpine. And then the Homer Tunnel takes you through the wall and out the other side into the Cleddau, where the whole thing tips downhill through rainforest to the sea.

The wildlife is better than the traffic deserves. The Eglinton is one of the last mainland strongholds of the mohua, the yellowhead — a bird that crashed to eighteen individuals here after the beech seed years around the turn of the century, fell again to fourteen in 2020/21, and has been dragged back to thirty-two by intensive trapping and by birds translocated in from Chalky Island and Dusky Sound. The valley also holds one of only two known mainland South Island populations of short-tailed bat. None of that is visible from a car at a hundred kilometres an hour, which is rather the point.

How to visit

Treat it as a day, not a drive. DOC's two hours is the figure for a car that does not stop; the regional tourism body says allow at least four, and four is right if you want more than a photograph of the Mirror Lakes. The practical consequence is that a Milford cruise and a proper run up this road do not fit comfortably into one day unless you leave Te Anau very early — and that is the strongest argument for driving up one day, sleeping, and cruising the next.

Go early. The coaches from Queenstown reach the middle of the road late morning and the middle of the day belongs to them. The first two hours after dawn on this road are close to empty, the light down the Eglinton is at its best, and the car parks at the Mirror Lakes and Lake Gunn are yours.

Knobs Flat is the halfway mark and the last useful stop. It has the last flush toilets before Milford, a public telephone in a place with no mobile coverage, interpretation panels on avalanches and wildlife, and a snow-chain fitting area. The name comes from the moraine hillocks around it; it was a road and tunnel workers' camp until the 1980s, and the accommodation on the site now is a private business rather than a DOC facility.

Camping is bookable and only bookable. There are eight DOC campsites strung along the road — Henry Creek, Walker Creek, Totara, Mackay Creek, Deer Flat, Kiosk Creek, Upper Eglinton and Cascade Creek — all graded Standard, at NZ$18 an adult and NZ$9 a child. DOC keeps no spaces for people who turn up: same-day booking is possible until 8pm if there is room, and if there is not, there is nowhere legal to stop. Freedom camping is not permitted within 200 metres of the road, there are no rubbish facilities anywhere, and drones need a permit.

Making the most of it

Distances below are from Te Anau, and every one of these is free.

Mirror Lakes, 56 km. A 400-metre boardwalk, ten minutes, wheelchair accessible, to small lakes that hold the Earl Mountains upside down when the air is still — which means early, before any wind. It is the most photographed stop on the road and it takes ten minutes, so the crowd turns over fast. There is a sign at the lake edge that reads correctly only in the reflection.

Lake Gunn Nature Walk, about 75 km. A 1.4-kilometre loop, forty-five minutes, DOC's easiest grade, through tall red beech with moss over everything and birdsong that is genuinely loud. DOC gives 71, 76 and 78 kilometres for this car park on three of its own pages, so trust the signs rather than an odometer. If you stop once between the Mirror Lakes and the tunnel, stop here rather than at a viewpoint.

The Divide and Key Summit, 85 km. The Divide is the lowest east-west pass in the Southern Alps and the start of the walk that is the best thing on this road: Key Summit, 6.8 kilometres return, about three hours, graded Intermediate and described by DOC as suitable for families with children. It climbs through forest onto an alpine bog plateau with a view down three separate valley systems, and it needs no Great Walk booking despite sharing its first section with the Routeburn. If you have three hours anywhere on this road, spend them here.

Monkey Creek, 96 km. Snowmelt water, kea, and sometimes whio, the blue duck, on the stream. Read the kea warning above before you stop, and never feed them — DOC is explicit that feeding kea harms them. (You will read that the creek water is safe to drink. No official source says so and we are not going to be the first.)

Gertrude Saddle, 98 km. Named here because people find it on a map and set off. This is Expert ground and it kills people. Four to six hours, steel cables bolted across rock slabs, no permanent markers above the bushline, and DOC's own advice is “if there's rain or snow, don't go”. It does not appear in DOC's day-walks brochure at all because DOC treats it as a route rather than a track. The Gertrude Valley below it is a fine hour's walk and an entirely different proposition.

The Chasm, 109 km — see the box above.

The Hollyford Road turns off at Marian Corner, 87 km, and is unsealed. DOC says allow two hours from Te Anau to the end of it. It gives access to Humboldt Falls (1.2 km return, thirty minutes, easy) and to Lake Marian — and Lake Marian needs a warning, because DOC grades it two different ways. Its web page calls it an Advanced tramping track needing moderate-to-high backcountry skills; its 2025 walks brochure calls it easy to intermediate. Take the harder grading. The Marian Falls boardwalk is 360 metres, ten minutes and genuinely easy; the lake itself is 3.1 kilometres each way, steep, muddy, an hour and a half up, and there is a live DOC alert about large amounts of ongaonga, the New Zealand stinging nettle. Wear long trousers. (Gunn's Camp, which older guides and some accommodation sites still list on this road, is described by DOC in the past tense. Do not plan on it.)

Nearby

Te Anau is the only sensible base — the road starts there, and it holds the last fuel, the last supermarket and the last mobile signal you will have until you come back. Everything on this page is a day trip from it.

The road ends at Milford Sound, which is where nearly everyone is going and which carries the practical detail about driving this route. Doubtful Sound runs in the opposite direction from Manapouri and needs its own full day. If the weather closes the road — it does, about eight days a year, mostly in winter — the lake, its fiords and the glowworm caves are all on the doorstep instead.
