Ulva Island

A Morning on Ulva Island

When Sarah from our BugBitten team stepped off the water taxi onto Ulva Island's weathered jetty, she was still zipping up her jacket. The crossing from Golden Bay Wharf had taken barely ten minutes, and the coffee she'd grabbed in Oban was still warm in her hand. She'd barely made it three steps along the boardwalk before a South Island Saddleback dropped out of the understorey and landed on a branch at elbow height, cocking its head to study her with the particular confidence of a creature that has never learned to be scared of anything walking on two legs.

That moment — the bird close enough to see every detail of its chestnut saddle without binoculars, the forest dense and dripping around her, the sound of the water taxi already fading — is what Ulva Island does to people. It recalibrates something. Most of us spend so long in places where wildlife flees before we can focus on it that we forget what it looks like when animals simply don't bother. On Ulva, they don't bother. The absence of predators has been in place long enough that the birds have developed what can only be described as a confident indifference to your presence, and that indifference turns an ordinary walk in the bush into something that stays with you for months.

What Makes This Island Worth the Journey

Ulva Island sits inside Rakiura National Park, about a kilometre off the shore of Stewart Island/Rakiura, which is itself one of the least-visited corners of New Zealand. Stewart Island sees a fraction of the tourist traffic that reaches Queenstown or the Milford Sound area — even in summer, the numbers stay modest — and Ulva is a step quieter again. The combination of genuine remoteness and relatively easy access by water taxi creates something unusual: a wild place that doesn't punish you physically just to reach it.

The island covers roughly 267 hectares and has been actively managed for predator control since the early 1990s. Stoats, rats, and possums — the main culprits behind New Zealand's catastrophic bird-loss story — have been removed and kept out through ongoing trapping and monitoring. The results are measurable and visible in a way that makes the conservation effort feel concrete rather than abstract. You're not being told species are recovering; you're watching a Saddleback land on a root two feet from your boot.

The forest itself is podocarp-broadleaf, dominated by rimu, miro, and rata. Rimu in particular grows to impressive scale here, with trunks wide enough that you instinctively want to photograph them against a person for scale. The canopy closes overhead into something that feels genuinely ancient, and beneath it, ferns and supplejack create a layered understorey that rewards slow walking. The track network is well-maintained by DOC standards, with clear signage at junctions and a main circuit that most fit walkers complete in three to four hours without rushing.

For context on how rare this kind of environment has become, New Zealand's subantarctic and island ecosystems — including Rakiura National Park — are recognised on the UNESCO World Heritage List as outstanding examples of largely intact southern hemisphere biodiversity. Knowing that before you arrive adds a layer of appreciation that holds up once you're actually standing in the forest.

How the Place Feels

There's a particular quality to forest sound on Ulva that's hard to name without being there. The density of birdsong — not just in variety but in volume — registers as unusual before you consciously identify what you're hearing. By mainland New Zealand standards it's extraordinary; by Australian bush standards it's almost confronting. Tui, Bellbird, Tomtit, Fantail, and the occasional Kaka work different parts of the canopy simultaneously, and the overlapping calls create something that sounds less like a nature documentary and more like a functional, working ecosystem.

The light inside the forest comes in filtered and green, shifting as cloud moves over the island. Stewart Island sits at 46 degrees south, which means even in midsummer the angle of light stays low enough to give the canopy a quality that photographers tend to get excited about. Overcast days — common, given the region's reputation for variable weather — create diffuse, even light inside the tree cover that suits forest photography better than hard sun would.

The jetty area, by contrast, is exposed and often busy with sandflies. This is not a minor observation. Ulva's sandfly population at the landing point is notable even by Southland standards, and Southland is not a region that takes sandflies lightly. You'll want repellent applied before the water taxi docks, not after.

The island has a consistent atmosphere of genuine quiet, even when other visitors are present. The trail network spreads people out effectively, and on most mornings you'll find sections of the main circuit where you're entirely alone in the forest. That solitude, combined with the bird activity, is the core of what makes Ulva work as an experience.

What to Actually Do Here

Walk the Main Circuit

The principal activity is walking the island's main track system, which loops through the best forest and passes several beach sections on the eastern and northern sides. The full circuit takes three to four hours at a pace that allows for stopping — and you will stop, constantly, because something will land near you or call from a branch directly above. Bring more time than you think you need.

The track surfaces vary. Some sections are well-compacted gravel or boardwalk; others are exposed root and mud, particularly after rain. Rubber-soled boots are the practical choice regardless of the forecast, because the forest floor stays damp even on dry days.

Watch for the Key Species

The South Island Saddleback (tīeke) is the species most people come for, and it rarely disappoints. They're active throughout the day and have a habit of following walkers along the track, apparently curious about what you might turn up. Their call — a series of descending whistles — is distinctive once you've heard it.

The Stewart Island Robin (toutouwai) behaves similarly, hopping along the track ahead of you and watching your feet with frank interest. If you stop and scuff the leaf litter gently, it will often approach to within half a metre.

Mohua (Yellowhead) work the higher canopy and require more patience and a decent pair of binoculars. They tend to move through the upper branches in loose groups, and hearing them before seeing them is the usual sequence. Yellow-crowned Parakeet (kākāriki karaka) appear overhead in fast, direct flight and are more often heard — a sharp, rapid chatter — than properly seen.

Consider a Guided Tour

Local operators based on Stewart Island run guided visits to Ulva. If separating bird calls in a dense understorey is not something you do regularly, a guide makes a genuine difference. They'll also tend to know where specific species have been active in recent days.

When to Go (and When Not To)

October through March covers the best window. Days are longest, bird activity is highest, and the forest is at peak vocal intensity during the breeding season from October through December. January and February offer more settled weather on average and the longest days, though "settled" is relative this far south.

April through September brings shorter days, quieter birds, and higher rainfall, but also significantly fewer other visitors. If solitude matters more to you than optimal bird activity, the shoulder and winter months have genuine appeal.

Avoid public holidays if you can. The water taxis from Oban get booked out, and the island — while never crowded by most standards — feels different when the jetty is busy.

How to Get There and Nearby Stops

Getting to Ulva starts with getting to Stewart Island, which means either the passenger ferry from Bluff (approximately one hour) or the small propeller aircraft service that runs from Invercargill. The ferry is the cheaper and more commonly used option; the flight is faster and gives you a view of the Foveaux Strait coastline that's worth considering if budgets allow.

From Oban — Stewart Island's only settlement — water taxis depart from Golden Bay Wharf and reach Ulva in around ten minutes. Taxis run throughout the day, and most operators allow you to book an outbound and return time when you go. Day trips are the standard approach and give you ample time for the full circuit.

Stewart Island itself has enough to justify two or three nights. Oban is small but functional, with accommodation ranging from DOC huts to comfortable lodge-style options, a pub, and a handful of cafés. The island's track network beyond Ulva includes multi-day routes for those with the kit and time. For a broader picture of what the region holds, more places in Southland covers options across the wider area.

Fiordland sits to the north and west, and many travellers combine Stewart Island with time at Fiordland National Park, which requires backtracking to the mainland but is a natural pairing for anyone doing a serious nature itinerary in the south. Equally, the iconic scenery of Milford Sound / Piopiotahi lies within reach for those extending their time in Southland.

The Not-So-Good Bits

The sandflies at the jetty are, without exaggeration, relentless. This is the most consistent complaint from every visitor, and it's entirely valid. Apply repellent before you land, cover your ankles and wrists, and accept that you'll probably still get bitten.

The track can be genuinely muddy and slippery after rain, and Stewart Island gets a lot of rain. If you arrive in light trainers, you'll regret it on the rooted sections. This isn't dangerous terrain, but it's uncomfortable underfoot without the right footwear.

Weather on Ulva and Stewart Island can change quickly. A clear morning from Oban doesn't guarantee conditions hold through the afternoon, and the crossing back on the water taxi in choppy conditions is not comfortable for anyone susceptible to motion sickness.

The ferry crossing from Bluff can be rough. The Foveaux Strait has a reputation, and on a bad day the hour-long crossing earns it. Anti-nausea medication is not a bad idea if you're at all prone.

Finally, accommodation in Oban is limited and books out well in advance during summer. Plan your stay well ahead — attempting to sort this on arrival is a gamble not worth taking.

Final Word from the BugBitten Team

Ulva Island is one of those places where the gap between expectation and reality closes completely. You arrive having been told the birds aren't afraid of you, and you think you understand what that means — and then a Saddleback lands at your feet and you realise you didn't understand it at all. The UNESCO World Heritage Centre designation that covers the broader Rakiura environment reflects something genuine: this is a functioning southern forest ecosystem in a state that most of the world no longer has, and you can walk through it on a well-marked track with good boots and a water bottle.

It's not a complicated experience. You take a boat, you walk through old forest, birds approach you without being asked, and you come back to Oban with muddy boots and an afternoon of very good photographs. The BugBitten team recommends it without qualification — not because it's dramatic or extreme, but because it does exactly what it sets out to do, reliably and honestly, and that's rarer than it sounds.

Pack the repellent. Wear the boots. Go early.
