Tunnel Beach Track

Out and back

The absolute crown jewel of this walk is the historic hand-carved tunnel that gives the beach its name. In the 1870s, John Cargill—son of Captain William Cargill, one of Dunedin’s founders—commissioned the excavation of this passage. Legend has it he wanted to provide his family with private access to the secluded beach below, away from the prying eyes of the public.

Descending the 72 stone steps into the cool, dim light of the tunnel feels like stepping into a secret world. The walls are rough-hewn, and the air smells of salt and damp earth. When you emerge at the bottom, you are greeted by a hidden cove that feels completely cut off from the rest of the world.

Once your feet hit the sand, look around. The beach is a geological playground. You’ll see massive sandstone boulders scattered like giants' marbles and a magnificent natural sea arch that dominates the northern end of the cove. If you’re a fan of natural history, keep your eyes peeled for fossils. The soft sandstone is rich with ancient secrets—you might spot the imprints of brachiopods (shellfish) or even extinct sea urchins embedded in the rock.

Getting There

Getting to the trailhead is straightforward, making it an easy addition to any Dunedin itinerary. Head south from the city centre and follow the signs for Blackhead Road. From there, turn onto Tunnel Beach Road and follow it to the very end.

• Summer (September – March): 8 am – 9 pm
• Winter (April – August): 9 am – 5 pm

The car park is relatively small, so it can get crowded during weekends and public holidays. If you’re driving a large campervan, be aware that turning space is limited when the lot is full. Roadside parking isn't permitted, so arriving early or late in the day is your best bet.

A quick local tip: Sadly, like many popular tourist spots, vehicle break-ins have been reported here in the past. Be sure to take your valuables with you or hide them completely out of sight before you head off on your walk.

Wildlife Spotting

The Otago coastline is a haven for native New Zealand wildlife. While you might be focused on the cliffs, keep an eye on the water and the sky.

• Little Blue Penguin (Kororā): These tiny locals are occasionally seen coming ashore at dusk. They are shy, so if you are lucky enough to spot one, give them plenty of space.
• Spotted Shag (Parekareka): Look for these elegant birds nesting on the narrow ledges of the sea stacks and cliffs. They are a common sight year-round.
• Southern Royal Albatross (Toroa): While their main colony is at Taiaroa Head, you can often see these magnificent birds—with their massive three-metre wingspans—soaring offshore.
• Variable Oystercatcher (Tōrea pango): You’ll likely hear their shrill piping call before you see them. These black birds with bright orange beaks are often found foraging among the rocks at the water's edge.

Along the headland, look down as well as up. You might see the critically endangered native coastal turf. This unique community of low-growing plants has adapted to survive the salt spray and high winds. Please stay on the formed track to avoid crushing these fragile little survivors!

Seasonal Magic & Practical Tips

The Tunnel Beach Track is a beauty in almost any weather, but it changes character with the seasons.

• Best Seasons: Summer and Autumn offer the most stable weather and the best light for photography. However, a Winter visit on a clear, crisp day can be stunning, as the Southern Ocean often puts on its most dramatic displays of power during the colder months.
• The Tide is Key: To get the most out of your visit, try to time your arrival for low tide. This allows you to explore the beach properly, walk through the sea caves, and get a better view of the fossils. At high tide, the sandy area can become quite small.
• What to Bring: Even on a sunny day, the wind at Tunnel Beach can be biting. Bring a windproof jacket, plenty of water, and sun protection. There is no shade on the track, and the Otago sun can be surprisingly fierce.
• No Swimming: It might look inviting, but the beach is notorious for dangerous rips and strong currents. It is unmonitored, so it’s best to keep your feet dry and enjoy the view from the shore.

Local & Regional Context

The history of this area is a fascinating mix of colonial ambition and geological wonder. The cliffs themselves are made of Caversham Sandstone, formed millions of years ago when this area was under the sea. The erosion you see today is a "work in progress," as the Southern Ocean continues to carve out new arches and stacks.

Culturally, the track is a reminder of Dunedin’s early settler history. The Cargill family were prominent figures in the 19th century, and the tunnel serves as a lasting monument to the lengths the Victorian elite would go to for a bit of privacy and coastal leisure. The track also passes through working private farmland; being mindful of livestock and staying on the path is a way of respecting the local families who continue to manage this land.

After the Walk

After you’ve tackled the steep 111m climb back to the car park, you’ll likely have worked up an appetite. Fortunately, the vibrant seaside suburb of St Clair is only a 10-minute drive away. It’s the perfect place to refuel and chat about the views.

• Titi Restaurant: For something a bit special, Titi offers exquisite dining with a focus on local Dunedin flavours and incredible views of the St Clair surf.
• Starfish Cafe & Bar: A local favourite for a casual post-hike brunch or a flat white. Their contemporary NZ cafe food is always fresh and satisfying.
• Salt Bar & Restaurant: Located right on the Esplanade, this is a great spot to grab a beer and a burger. If it’s a chilly day, their cosy fireplace is a dream.
• Spirit House: If you’re craving something spicy, Spirit House serves up fantastic authentic Thai cuisine in a very welcoming, family-friendly atmosphere.

The Tunnel Beach Track is a quintessential Dunedin experience—wild, historic, and undeniably beautiful. It’s a short walk that leaves a long-lasting impression, reminding us of the raw power of nature and the quirky stories of those who walked these cliffs before us.
