Why hike it

If you want the Routeburn’s greatest hits in one day, this west-side segment delivers: lush beech forest, a thundering 174 m waterfall you can walk beneath, an open subalpine meadow, and a mirror-still lake ringed by mountains. It’s a well-formed Great Walk track that still makes you earn the views.

The experience

Starting at The Divide trailhead, the track climbs steadily through temperate rainforest—think moss-draped beech, ferns, and damp, green everything—before opening toward subalpine terrain. You’ll pass the Key Summit junction and continue to Earland Falls, a spectacular 174 m drop where the route usually passes right under the spray; in high flows there’s a small bridge detour. Beyond, “The Orchard” provides a breather: a grassy, ribbonwood-dotted clearing with big views back to the falls and the surrounding peaks.

The finale is Lake Mackenzie, a serene subalpine basin with clear reflections and a hut tucked near the shore. The lake itself is about 23 hectares and 13 m deep—classic glacial country with scoured rock and a wide, U-shaped feel to the valley. Expect a mix of benched gravel tread, rock steps, and bridges throughout.

Distance, time, and difficulty

It’s approximately 12 km/7.5 miles one way from The Divide to Lake Mackenzie Hut, typically taking 4–5 hours for most hikers. The track is rated moderate: well-built but sustained, with roughly 330–400 m of ascent, plus some short, steeper zig-zags near the lake.

Logistics and crowds

This is a point-to-point segment of the Routeburn Great Walk. Many hikers arrange shuttles in Great Walk season; otherwise, be prepared for a long out-and-back. Lake Mackenzie Hut is the natural stop—bookings are essential in season and fill quickly. The Divide carpark has a shelter and toilets; the hut area has toilets and designated camping.

Best time to hike

Late October to late April is the sweet spot (Great Walks season) when the track is fully maintained and the hut is serviced. Outside this window, expect winter hazards like snow, ice, and avalanche risk. Weather in Fiordland is moody year-round—bring rain gear and warm layers even on bluebird forecasts. Photographers: dawn and dusk at Lake Mackenzie are prime for color and reflections.

Tips you’ll thank us for

Check track updates before you go; heavy rain can make the Earland Falls/The Orchard section impassable.
Pack insect repellent—sandflies are enthusiastic near water and lower elevations.
If the falls are raging, use the signed bridge detour rather than pushing through the spray.
Book huts early in peak season; this one is no secret.

Is it worth it?

Absolutely. The rainforest-to-alpine contrast, the drama of Earland Falls, and the calm of Lake Mackenzie make this one of the Routeburn’s most rewarding legs without requiring mountaineering skills.

Pros

You can pass directly beneath 174 m Earland Falls (bridge detour in high flow).
The Orchard’s ribbonwood meadow gives rare open views on a mostly forested approach.
Lake Mackenzie’s calm water delivers standout sunrise/sunset reflections for photography.

Cons

Not a loop—requires shuttle logistics or a long out-and-back.
Sections near Earland Falls and The Orchard can be impassable after heavy rain.
Sandflies can be intense at lower elevations and near the lake.

Parking

Park at The Divide carpark on SH94 (Te Anau–Milford Highway); there’s a shelter and toilets at the trailhead.

Caution

Rapid weather changes year-round; heavy rain can flood sections near Earland Falls/The Orchard. Outside Great Walks season, expect snow, ice, and avalanche risk. Track can be slippery; use the bridge detour at Earland Falls in high flow. Sandflies are common—carry repellent.
