Mistake Creek Track

What to expect

This is Fiordland at its rawest: a rough, wet, and wonderfully wild tramping track up Mistake Creek Valley. From the Earl Mountain Tracks carpark on Milford Road, you cross the Eglinton River via a single walk wire, then turn hard right to follow Mistake Creek up-valley. The track threads through dense beech forest before easing onto river flats at the bush edge, with big Earl Mountains looming on all sides.

It’s only 5 km one way (about 3.1 miles) to the flats, but don’t be fooled—travel is slow. Expect mud, overgrown sections with head‑high ferns and flax, and multiple unbridged crossings where water levels can spike after rain. Navigation is straightforward in the bush, then gets vague on the open flats; confident route‑finding is a must. If you’re looking for a formed, polished trail, this isn’t it.

Scenery

You’ll move from shadowy red/beech forest and mossy creek banks to open tussock and grassy river flats framed by the Earl Mountains. Clear mountain streams and glaciated valley walls set the alpine tone. Those continuing beyond the flats toward U Pass (an advanced, alpine link to Hut Creek) encounter steeper tussock and scree; trip reports mention a dramatic waterfall in the valley and a true‑right bypass dubbed the “Improbable Staircase.”

Distance and time

• Length: 5 km/3.1 miles one way; 10 km/6.2 miles out‑and‑back to the flats.
• Typical time: around 3–4 hours return for experienced trampers, conditions permitting.

Who it’s for

Experienced trampers with solid river‑crossing skills and navigation. Beginners and fair‑weather walkers will find this frustrating or unsafe, especially after rain.

Tips

• Footwear and layers: waterproof boots, warm/waterproof clothing; you will get wet.
• Navigation: carry map and compass/GPS; the track becomes vague on the flats.
• Safety: carry a PLB; rivers rise fast—wait them out if high. The walk wire helps at the Eglinton, but it’s still a committing backcountry trip.
• Link‑ups: Strong parties often connect with Hut Creek via U Pass for a rugged transalpine loop—advanced skills required.

Best time to hike

Summer to early autumn offers the most reliable weather and safer river levels. Winter and spring bring short days, cold temps, avalanche considerations in upper terrain, and extra‑hazardous crossings—only go if you have the training, gear, and a good window.

Crowd factor

Low. This valley sees a fraction of the foot traffic found on Fiordland’s marquee tracks, which is exactly the appeal if you’re after solitude.

Nearby alternative

Falls Creek Route starts from the same carpark and offers similarly rugged alpine access—another good option if you’re shopping for a serious challenge.
