Tautuku Estuary Walkway

Out and back

Highlights & Must-See Features

The undisputed star of the show at Tautuku is the oioi, or jointed rush. This endemic New Zealand plant dominates the landscape once you leave the forest. While "rushes" might sound plain, the oioi creates a stunning tapestry of greens, burnt oranges, and deep reds. Depending on the light, the entire estuary can appear to change colour. For the best photo opportunities, try to time your visit for the "golden hour" at sunrise or sunset. When the low sun hits the oioi, the stalks glow with an ethereal light that is a dream for landscape photographers.

Another highlight is the viewing platform at the end of the boardwalk. This is the perfect spot to stop, breathe, and simply listen. Because the estuary is so flat, sound travels remarkably well. You can hear the distant crash of the Pacific Ocean waves and the rustle of the wind through the rushes. It provides a 360-degree panoramic view that captures the essence of the Catlins: where the forest meets the water.

For those interested in the human side of the landscape, keep an eye out for the remnants of the area’s sawmilling history. The very path you walk on was once a hive of industrial activity. It is humbling to see how the forest has reclaimed the land, turning a former logging route into a sanctuary for native species.

Getting There

Finding the Tautuku Estuary Walkway is half the fun, as it takes you along the famous Southern Scenic Route, one of the most beautiful drives in the world.

If you are driving south from Dunedin or Owaka, keep an eye out for the Forest and Bird Society Lodge (Tautuku Lodge) near Tautuku Bay. Directly opposite or nearby, you will see a signposted turn-off for the Tautuku Estuary. You will need to turn onto a two-kilometre gravel access road. While it is unsealed, it is generally well-maintained and suitable for standard vehicles, though you should always drive to the conditions.

The road ends at a dedicated car park. There are no fancy visitor centres here—just the wild bush and the start of the trail. Be sure to lock your vehicle and take any valuables with you, as the car park is somewhat secluded.

Wildlife Spotting

The Tautuku Estuary is a haven for birdwatchers. The mix of podocarp forest and salt-marsh wetland means you get the best of both worlds.

In the forested section, you are almost guaranteed to see and hear the Tui and Bellbird (Korimako). Their melodic calls are the constant soundtrack of the walk. You should also keep a sharp eye out for the New Zealand Pigeon (Kererū); these heavy-set birds are often seen perched precariously on thin branches, feasting on berries. Fantails (Pīwakawaka) will likely follow you along the track, flitting about to catch the insects disturbed by your footsteps.

However, the real prize for wildlife enthusiasts is the elusive Fernbird (Mātātā). This small, brown, streaky bird is a specialist of the wetlands. It isn't a strong flier, so it spends most of its time scurrying through the oioi like a mouse. You are more likely to hear its distinctive "u-tick" call than to see it. If you stay very still on the boardwalk or the viewing platform, you might see one pop its head up.

Out on the mudflats and near the water’s edge, look for the Pied Stilt (Poaka) with its long pink legs, and the Kingfisher (Kōtare), which often perches on overhanging branches or the boardwalk railings, waiting for a movement in the water below.

Seasonal Magic & Practical Tips

The Tautuku Estuary Walkway is a true year-round destination, but each season brings a different flavour to the experience:

• Spring: This is when the birdlife is most active. The Tui and Bellbirds are in full song, and the forest feels incredibly alive with new growth.
• Summer: The most popular time to visit. The weather is generally warmer, and the boardwalk provides a dry path even if there have been summer showers.
• Autumn: The light in autumn is spectacular for photography, and the colours of the oioi seem to deepen into richer bronzes and golds.
• Winter: The Catlins in winter is moody and atmospheric. A crisp, frosty morning followed by a walk here is magical, though you’ll want to wrap up warm against the coastal breeze.

• Time of Day: Early morning or late afternoon is best. Not only is the light better for photos, but the wind tends to drop, and the birds are more active.
• What to Wear: Even in summer, the Catlins weather is unpredictable. Bring a waterproof jacket and a warm layer. The track is easy, so sturdy sneakers or walking shoes are perfectly fine—no need for heavy hiking boots.
• Sun & Bug Protection: Even on cloudy days, the NZ sun is fierce. Wear sunscreen. Also, being a wetland, the sandflies can be persistent if you stand still for too long, so a bit of insect repellent is a good idea.
• Weather Considerations: The estuary is quite exposed. If there is a strong southerly or "nor'west" wind blowing, it can feel quite chilly on the boardwalk.

Local & Regional Context

This area is far more than just a pretty view; it is a place of immense cultural and ecological value. For Māori, the Tautuku area has long been a significant site for food gathering (mahinga kai) and as a coastal transit route. Today, the estuary is classified as a coastal protection area. This status acknowledges its role as a vital breeding ground for fish and a filter for the local ecosystem.

The surrounding forest is a "living fossil." Seeing these massive podocarps standing tall is a reminder of what New Zealand looked like before human arrival. The local community and organisations like Forest and Bird have put immense effort into conservation here, including predator control to protect the mātātā and other ground-nesting birds. By staying on the boardwalk, you are helping to protect the fragile root systems of the wetland plants that keep this ecosystem thriving.

After the Walk

After you’ve finished your 30-minute exploration, you’ll likely have worked up an appetite for more than just scenery. Just five kilometres down the road (about a 5-minute drive) is The Whistling Frog Cafe & Bar.

This is a legendary spot in the Catlins and is the perfect place to refuel. It’s got a wonderfully relaxed, "kiwi" atmosphere that welcomes hikers and travellers with open arms. Whether you want a full meal, a slice of homemade cake, or a cold craft beer to celebrate your walk, they’ve got you covered. It also serves as a great hub to chat with other travellers and get tips on the next hidden waterfall or beach to visit.

The Tautuku Estuary Walkway might be a short walk, but the sense of peace and the connection to nature it provides will stay with you long after you’ve left the Catlins.

Bellbird

Anthornis melanura

Endemic songbird with bell-like calls. Males are olive-green with a purple head sheen; females are browner with a narrow white-yellow stripe across the cheek.
