Lakehead Loop Track

Loop

Another highlight is the Rotoiti Nature Recovery Project area. Thanks to intensive pest control, this forest is "louder" than many others in New Zealand. The sheer volume of birdsong is a testament to the hard work of local conservationists.

For the photographers, there are several "peek-a-boo" viewpoints where the forest opens up to reveal the lake. The contrast between the deep greens of the beech forest, the dark trunks covered in black sooty mould, and the brilliant turquoise or deep blue of the lake is spectacular. Don't forget to stop at the various interpretation panels along the way; they offer fascinating insights into how glaciers carved this landscape thousands of years ago and the diverse flora that has reclaimed the valley since.

Getting There

Finding the trailhead is a breeze. If you are staying in the village of St Arnaud, you can simply walk down to the lakefront. For those driving in, head to the Kerr Bay Campsite. There is a large, free parking lot available right at the lakeside.

From the parking lot, look for the Department of Conservation (DOC) signs near the water’s edge. The loop is well-signposted, initially following the shoreline before veering into the forest. Because it’s a loop, you can technically walk it in either direction, but most locals prefer heading clockwise to get the "climbing" parts out of the way early while finishing with the easy lakeside sections.

Wildlife Spotting

Pack your binoculars, because the Lakehead Loop is a haven for native birdlife. The forest is absolutely teeming with Tui, Bellbirds (Korimako), and Fantails (Piwakawaka). You’ll likely hear the melodic, bell-like chiming of the Bellbirds long before you see them.

Keep a sharp eye on the forest floor or low branches for the South Island Robin (Toutouwai). These friendly little birds are notoriously curious and will often hop right up to your boots to see if you’ve kicked up any tasty insects from the leaf litter. High in the canopy, you might spot the large, heavy Kererū (New Zealand Pigeon) swooping between trees with their distinctive "whoosh-whoosh" wing beats.

On the water, look out for the New Zealand Dabchick (Weweia), a rare and stylish little water bird. If you’re incredibly lucky (and perhaps out near dusk), you might hear the shrill whistle of a Great Spotted Kiwi, though they remain very elusive. Remember, this area is a no-dog zone to protect these precious feathered residents, so please leave your four-legged friends at home.

Seasonal Magic & Practical Tips

• Spring: The forest is at its most vibrant, and the birdsong is deafening as the breeding season kicks into gear.
• Summer: The canopy provides a cool, shaded sanctuary from the sun. The lake is inviting for a post-hike swim at Kerr Bay.
• Autumn: The air turns crisp and clear, often providing the best reflections on the lake.
• Winter: St Arnaud can turn into a winter wonderland. While the track might be frosty or have a light dusting of snow, the forest looks magical. Just watch out for icy patches on the bridges!

Best time to start: Aim for early morning. Not only is the lighting better for photos, but the birds are most active during the "dawn chorus." Plus, you’ll beat any afternoon winds that might ruffle the lake’s glassy surface.

• Footwear: Sturdy sneakers are fine in dry weather, but hiking boots are recommended if it’s been raining.
• Layers: This is alpine country. Even in summer, the temperature can drop quickly if a southerly blow comes through. Carry a waterproof jacket.
• Insect Repellent: The sandflies at Kerr Bay are legendary and very hungry. Apply repellent before you leave your car!
• Sun protection: Even under the trees, the NZ sun is fierce. Wear a hat and sunscreen.

Local & Regional Context

Nelson Lakes National Park holds deep significance for New Zealanders. For Māori, the lakes (Rotoiti and Rotoroa) are part of the traditional trails used by iwi (tribes) travelling between the east and west coasts. The area is rich in stories of the great explorer Rakaihautu, who is said to have dug the lakes with his ko (digging stick).

Geologically, you are standing on the edge of the Alpine Fault, one of the world's major plate boundaries. The dramatic landscape of the St Arnaud Range was sculpted by massive glaciers during the last ice age, leaving behind the deep basins that now hold the lakes.

The Rotoiti Nature Recovery Project, established in the late 1990s, is one of New Zealand's "mainland islands." It covers about 5,000 hectares of beech forest and aims to restore the ecosystem by trapping pests like stoats, rats, and wasps. When you hear the birds today, you are listening to the success of decades of conservation work.

After the Walk

After two hours of exploring the bush, you’ll likely have worked up an appetite. Fortunately, St Arnaud has some excellent spots to refuel, all within a few hundred metres of the trailhead:

1. Alpine Lodge Restaurant & Bar: Just a 300m walk from the lake, this is the spot for a proper "sit-down" meal. They use fresh, local produce and the atmosphere is wonderfully cosy. It’s a great place to grab a craft beer and sit by the fire in winter or on the deck in summer.
2. NPD St Arnaud Alpine Store & Cafe: If you’re after something quick, this is your go-to. They serve great coffee, classic Kiwi pies, and cafe meals. In the summer evenings, their takeaway fish and chips are a local favourite—perfect for taking back down to the lakefront for a picnic.
3. St Arnaud Tavern: A classic local pub just 400m away. It’s unpretentious, friendly, and serves the kind of hearty fare that hikers crave. It’s a brilliant spot to swap stories with other travellers.

The Lakehead Loop Track isn't just a walk; it’s an immersive experience in one of New Zealand’s most accessible and beautiful national parks. Whether you're a seasoned tramper or a family looking for a weekend adventure, this trail offers a rewarding and unforgettable slice of the South Island.

Poliocephalus rufopectus

This endemic, shy diving bird builds floating nests and is notable for carrying its young chicks on its back, though it is now rare in the South Island.

Best time: Year-round
