If you are looking for a trail that tests your mettle, rewards your grit with staggering views, and plunges you deep into the heart of the Manawatū wilderness, the Otangane Loop Track is calling your name. Tucked away in the Kahuterawa Valley, just a short 20–25 minute drive from the hustle of Palmerston North, this isn't your average Sunday stroll. It is a true backcountry experience that demands respect, sturdy boots, and a bit of a "can-do" attitude.
While many locals are familiar with the gentle riverside paths of the Sledge Track, the Otangane Loop is for those who want to go further, higher, and deeper into the Tararua Forest Park. It’s a trail of two halves: a picturesque riverside meander followed by a climb that will have your lungs burning and your camera roll filling up. Whether you’re a seasoned tramper or a local looking to level up your weekend adventures, this 8.5km loop (as part of a longer day trip) offers a sense of isolation and achievement that is hard to beat so close to the city.
The journey to the Otangane Loop Track is an adventure in progression. Your day begins at the Kahuterawa Valley carpark, where you’ll set off along the well-loved Sledge Track. This initial section is a dream—a relatively flat, lush meander through native bush that follows the sparkling Kahuterawa Stream. You’ll pass the famous Argyle Rocks and several tempting swimming holes that look like something out of a postcard. This part of the track is shared with the Arapuke Mountain Bike Park network, so keep an ear out for the whirr of tyres and offer a friendly wave to the riders.
However, the "easy" part ends once you cross the Arapuke swing bridge. From here, the trail transforms. You’ll find yourself staring up at a section aptly named ‘The Elevation’. It is exactly what it sounds like: a steep, gut-busting climb that separates the casual walkers from the trampers. As you push upward, the sounds of the stream fade, replaced by the heavy rhythm of your breath and the rustle of the canopy above.
Once you reach Toe Toe Junction, the real Otangane Loop begins. The track heads west and then south, diving deep into Harding’s Park. This is where the "hard" difficulty rating truly earns its stripes. The terrain becomes uneven and rugged. This isn't a manicured gravel path; it’s a raw, immersive bush experience. You can expect plenty of "bush bashing" sections where the native flora—including the notorious hook grass and the prickly bush lawyer—might try to hitch a ride on your gear.
Parking is available at the Kahuterawa Valley Carpark, located at the end of Kahuterawa Road. Access is via a gravel road off Old West Road from State Highway 57, which may be uneven. The carpark accommodates multiple vehicles and is a popular starting point for various trails in the area. A single composting/non-flush public toilet is provided at the carpark.

Loop
The loop circuits the headwaters of the Otangane Stream, and while the track is well-marked with orange triangles, you’ll need to keep your wits about you. It’s muddy, it’s slippery after rain, and it feels wonderfully wild. While the loop itself is 8.5km, remember that you have to get there and back via the Sledge Track, making the total journey a substantial 16–19km mission that usually takes between 6 and 8 hours.
The undisputed crown jewel of this hike is Pukenaenae. As you emerge from the denser sections of the bush onto the higher ridges, the world opens up. On a clear day, the panoramic vistas down into the Tararua District are nothing short of spectacular. It’s the perfect spot to catch your breath, enjoy a sandwich, and realise just how far above the valley floor you’ve climbed.
Another highlight is the transition of the forest itself. You move from the damp, fern-heavy riverside environment of the Kahuterawa Valley into the more rugged, wind-swept sub-alpine character of the Tararua ranges.
For the geologically minded, the Argyle Rocks near the start of the walk are a must-see. These massive, ancient rock formations in the stream bed provide a dramatic backdrop for photos. And if you’re tramping in the warmer months, the crystal-clear swimming holes along the Sledge Track are the ultimate "must-see" (and "must-jump-into") on your way back to the car. There is nothing quite like the shock of cold mountain water to soothe legs that have just survived the Otangane bush.
Getting to the trailhead is straightforward, making it a favourite for Palmy locals. From Palmerston North, head south on State Highway 57 (Old West Road) and turn onto Kahuterawa Road. Follow this road all the way to the very end.
The final stretch is a gravel road which can be a bit uneven and dusty, so take it slow, especially if you’re in a smaller car. The Kahuterawa Valley Carpark is a large, open area that can accommodate plenty of vehicles, though it does get busy on sunny weekends. You’ll find a single composting, non-flush public toilet here—it’s basic, so it’s a good idea to bring your own hand sanitiser.
The Kahuterawa Valley is a sanctuary for native New Zealand birdlife, and the deeper you go into the Otangane Loop, the more vocal they become.
Tip: The best time for birdwatching is early morning or late afternoon when the "dawn chorus" or evening songs are at their peak. Bring a pair of compact binoculars if you have them!
The Otangane Loop Track is open year-round, but your experience will change significantly with the seasons.
Dog Owners: Good news! This trail is dog-friendly, provided your pooch is on a lead. Just ensure they are fit enough for a 7-hour mission and that you pack enough water for them too. Note: This track is not kid-friendly due to the sheer length, steepness, and rugged terrain.
The area surrounding the Otangane Loop is part of a significant conservation and recreation hub. Harding’s Park and the wider Tararua Forest Park are steeped in history. For Māori, the Tararua ranges are a place of great spiritual significance, often associated with the explorer Hau, who named many of the rivers in the lower North Island.
In more recent history, the valley was used for logging and farming, but today it is a testament to the power of regeneration. The Arapuke Mountain Bike Park and the maintenance of tracks like the Otangane Loop are the result of incredible work by local councils and volunteer groups. By walking here, you’re stepping into a landscape that is being carefully preserved for future generations of adventurers.
After 7 or 8 hours in the bush, you’ll likely be dreaming of a cold drink or a hot meal. Head back into Palmerston North (specifically the Summerhill area or the CBD) to refuel:
The Otangane Loop Track isn't just a hike; it’s a rite of passage for Manawatū trampers. It’s tough, it’s wild, and it’s undeniably beautiful. Pack your bags, lace up your boots, and go get stuck in!
