Mount Robert Circuit

Loop

Highlights & Must-See Features

The standout attraction of the Mount Robert Circuit is, undeniably, the panoramic vistas of Lake Rotoiti. There are several "photo stops" along the ridgeline where the lake is perfectly framed by the surrounding mountains.

Bushline Hut is another highlight. Even if you aren't staying the night, the hut's deck offers one of the best lunch spots in the region. It’s a great example of New Zealand’s tramping culture—rugged, functional, and situated in a location that a five-star hotel would envy.

Keep an eye out for the unique alpine flora. Above the bushline, the landscape is dotted with hardy tussocks, mountain daisies, and specialized plants that cling to the rocky slopes. The transition from the lush, green beech forest to this stark, beautiful alpine environment is one of the most interesting geological features of the walk.

Getting There

To reach the trailhead, drive to the village of St Arnaud. From there, follow Mount Robert Road for about 5km until you reach the end. Be aware that the road is gravel, narrow, and can be quite winding. Take it slow, especially on the corners.

The Mount Robert Carpark has toilets available, which is handy before you set off. However, a few words of caution: this carpark is a known hotspot for opportunistic thieves. Ensure you don't leave any valuables in your vehicle, and try to make the car look as empty as possible. Also, if you are driving a campervan or a large vehicle, note that vehicles longer than 7 metres are not recommended on this road due to the tight turns and narrow sections. On sunny weekends, the carpark fills up by mid-morning, so an early arrival is highly recommended to secure a spot.

Wildlife Spotting

Nelson Lakes is a haven for native birdlife, and the Mount Robert Circuit provides a fantastic cross-section of habitats to explore.

In the lower beech forests, keep an ear out for the melodic chime of the Bellbird (Korimako) and the boisterous call of the Tūī. You are almost certain to encounter the South Island Robin (Toutouwai); these friendly little birds are famously curious and will often hop right up to your boots to see if you’ve stirred up any insects in the leaf litter.

As you move into the higher forest and near the bushline, listen for the high-pitched "zee-zee" of the Rifleman (Tītitipounamu), New Zealand’s smallest bird. If you are very lucky, you might spot the rare Yellowhead (Mohua).

Once you hit the alpine zone, keep your eyes on the sky. The Kea, the world’s only alpine parrot, is an occasional visitor here. They are highly intelligent and inquisitive, but remember: never feed them, no matter how much they beg for your sandwich!

Seasonal Magic & Practical Tips

• Best Seasons: The circuit is beautiful year-round, but each season brings a different vibe. Summer offers the most stable weather and the longest days. Autumn is often stunning with crisp, clear air and golden light. Spring sees the alpine flowers beginning to bloom, though the track can be muddy from snowmelt. Winter transforms the circuit into a true alpine challenge—snow and ice are common, and you may need crampons and an ice axe (plus the knowledge of how to use them) to complete the loop safely.
• Timing: Start as early as possible. Not only does this help with parking, but it also ensures you aren't slogged by the afternoon sun on the exposed ridgeline, which can get surprisingly hot in mid-summer.
• Weather: The weather in the Southern Alps can change in an instant. Even if it’s sunny in St Arnaud, the ridge can be lashed by freezing nor'west winds or shrouded in cloud within minutes. Always carry a waterproof jacket, a warm hat, and gloves.
• Gear: Wear sturdy hiking boots with good grip. Bring plenty of water, as there are no reliable water sources on the ridge itself. Sun protection is vital—the New Zealand sun is fierce, especially at altitude.

Local & Regional Context

The area around Lake Rotoiti and Lake Rotoroa holds deep significance for Māori, particularly for the Ngāti Apa ki te Rā Tō iwi. According to legend, the lakes were carved out by the great explorer Rākaihautū using his digging stick (tuwhakaroria), creating the "food baskets" that provided sustenance for generations.

The name Rotoiti translates to "Little Lake," while Rotoroa means "Long Lake." Historically, this region was a vital travel route for Māori moving between the east and west coasts of the South Island, particularly in the search for pounamu (greenstone).

Geologically, the landscape is a masterclass in glacial action. The massive U-shaped valleys and the moraine wall that holds Lake Rotoiti in place are reminders of the enormous glaciers that once dominated this region. Today, the area is a focal point for conservation, with the Rotoiti Nature Recovery Project working hard to control pests and bring back the dawn chorus that once filled these valleys.

After the Walk

After five hours on the trail, you’ll likely be ready for some serious refueling. Head back down to St Arnaud village (just 5km away) where you have a few excellent options:

• Alpine Lodge: This is the local hub for a hearty meal. Their takeaway pizzas are legendary among hikers, and the cozy restaurant is a great place to sit by the fire with a cold beer or a glass of Nelson sauvignon blanc.
• St Arnaud Alpine Store: If you’re after something quicker, the store offers great coffee and a range of cabinet food and takeaway options. It’s the perfect spot to grab a meat pie or a sandwich to enjoy by the lakefront.
• The Clinker Café: Another fantastic local spot for refreshments, offering a friendly atmosphere and plenty of treats to reward your efforts on the mountain.

The Mount Robert Circuit is more than just a hike; it’s an invitation to stand on top of the world for a moment and appreciate the raw beauty of the South Island. Put it at the top of your Nelson Lakes bucket list!
