Tomahawk Lagoon Track

Out and back

Highlights & Must-See Features

The absolute crown jewel of this hike is the Soldiers' Monument. Perched high on the ridge, this stone cairn is a deeply moving tribute to the 49 men from the Otago Peninsula who gave their lives during World War I. Reaching the monument provides a natural point for reflection, but it also serves as one of the finest vantage points in Dunedin. From here, you are treated to a staggering 360-degree panorama. To the west, the sprawl of South Dunedin and the city; to the east, the rugged, undulating spine of the Otago Peninsula; and to the south, the endless, sparkling blue of the Pacific Ocean.

Another highlight is the lagoon itself. As a significant brackish wetland managed by the Department of Conservation (DOC), it is a rare ecological treasure. Even if you aren't a dedicated birdwatcher, the sheer volume of birdlife is impressive.

Keep your eyes peeled for the historic stone walls that criss-cross the farmland as you climb. These hand-stacked walls are a silent testament to the early Scottish settlers who cleared this land, using the volcanic basalt rock of the peninsula to create boundaries that have stood the test of time and weather for over a century.

Getting There

Finding the trailhead is straightforward. From Dunedin city, head south towards Andersons Bay and follow the signs toward Ocean Grove (formerly known as Tomahawk). Follow Tomahawk Road until it turns into Oregon Street.

You’ll find the Tomahawk Carpark easily on your left. It’s a great spot with plenty of room and even includes a picnic area if you want to have a snack before or after your hike. The trail starts at the far end of the carpark—just look for the gap in the fence and the signage indicating the start of the lagoon walk.

Wildlife Spotting

The Tomahawk Lagoon Track is a paradise for bird enthusiasts. Because the lagoon is a mix of fresh and salt water, it attracts a diverse range of species.

• Black Swans: These are the most iconic residents of the lagoon. You’ll see them gliding majestically across the water year-round.
• Pied Stilts: Look for these long-legged birds wading in the shallows near the start of the track.
• White-faced Herons: Often seen standing perfectly still on the water’s edge, waiting for a meal.
• Fantails (Pīwakawaka): These friendly little birds will likely follow you through the bush sections, flitting around to catch the insects you stir up as you walk.
• Marsh Crake: If you are very quiet and very lucky, you might spot this rare, secretive bird in the reed beds.

Tip: Bring a pair of binoculars! The best time for bird spotting is early morning when the lagoon is at its stillest and the birds are most active.

Seasonal Magic & Practical Tips

The Tomahawk Lagoon Track is a true four-season trail, each bringing its own flavour to the experience.

• Spring: The regenerating bush is vibrant with new growth, and you’ll likely see cygnets (baby swans) on the lagoon.
• Summer: The best time for those clear, blue-bird days where the Pacific Ocean looks like glass. Be aware that the farmland sections can get quite hot as there is little shade, and the grass may be long.
• Autumn: The air is often crisp and clear, providing the best visibility for the views from the Soldiers' Monument.
• Winter: Dunedin winters bring a moody beauty. The track can be muddy and slippery, so sturdy footwear or hiking boots are a must. The wind off the ocean can be biting, so a good windbreaker is essential.

• Footwear: Even in summer, the terrain is uneven. In winter, it’s muddy. Wear boots or high-grip trail shoes.
• Layers: This is coastal Dunedin. The weather can change from sunshine to a southerly nipper in minutes. Carry a warm layer and a waterproof jacket.
• Sun protection: Once you leave the bush and enter the farmland, you are completely exposed. Wear a hat and sunscreen.
• Water: There are no water taps along the route, so bring at least a litre per person.

Local & Regional Context

The name "Tomahawk" has a fascinating, if somewhat debated, history. It is widely believed to be an anglicised version of the Māori words toma haka. While toma can mean "bones" and haka refers to a dance or performance, some interpret the name as "dance by a gravesite." While no specific pre-European burial sites have been officially confirmed right on the track, the area was a well-known part of the traditional Māori trail network used to navigate the peninsula.

The lagoon and the surrounding dunes were vital mahinga kai (food gathering) sites for local iwi. Today, the area is a focus of local conservation efforts, with community groups and DOC working hard to restore the water quality and native vegetation of the wetland. Walking here, you are stepping through a landscape that has transitioned from a Māori highway to colonial farmland, and now into a valued ecological and recreational reserve.

After the Walk

After two hours of coastal air and hill climbing, you’ll likely have worked up an appetite. Luckily, you don't have to go far for a refuel.

Just 3km (about a 5-minute drive) away is Nichol's Garden Cafe Dunedin. This is a fantastic spot for hikers. It has a warm, welcoming indoor area for those chilly winter days and a sheltered outdoor space for the summer.

They serve excellent barista-made coffee and have a cabinet full of fresh deli food—perfect if you’re after a quick savoury scone or a "big breakfast" to reward your efforts. While the Tomahawk Lagoon Track itself doesn't allow dogs, the outdoor area at Nichol's is dog-friendly, making it a great place to meet up with friends who might have been out for a different stroll with their pups.

The Tomahawk Lagoon Track is a quintessential Dunedin experience—a bit rugged, steeped in history, and breathtakingly beautiful. It’s the perfect reminder of why we love living in or visiting this "wild" city.
