If you are looking for a quintessential coastal experience in The Catlins, Jack’s Blowhole Track is a walk that perfectly captures the wild, untamed spirit of the South Otago coastline. This 3-kilometre return journey is more than just a stroll to a hole in the ground; it’s an immersive experience through the heart of New Zealand’s rural and coastal identity. Rated as an easy walk, it is accessible for most fitness levels and is a fantastic option for families looking to get the kids out into the fresh salt air.
The adventure begins at the southern end of Jack’s Bay, a secluded and charming settlement known for its traditional kiwi 'cribs' (holiday homes). After parking up, you’ll find the trailhead well-marked. The first thing you’ll notice is the transition from the soft sands of the bay to a well-formed gravel path that immediately begins a gentle ascent.
One of the most charming aspects of this walk is that it traverses private farmland. You’ll feel like a true local as you navigate stiles—those classic wooden steps used to cross over fences—while sheep graze nearby, seemingly indifferent to the spectacular views unfolding behind them. As you climb the modest 123-metre elevation gain, the landscape opens up. To your north, you can look back across the sweep of Jack’s Bay and out toward Tuhawaiki Island. On a clear day, the rugged silhouettes of Surat Bay and Cannibal Bay stretch out in the distance, framed by the white-capped waves of the Pacific Ocean.
The track then skirts a lush, forested gully. This is a beautiful contrast to the open paddocks, offering a cool, shaded reprieve where you can spot native New Zealand flora like ngaio and poroporo. The path remains easy to follow, and before long, the sound of the ocean begins to change. Instead of the rhythmic crashing of waves on a beach, you’ll hear a deep, guttural boom echoing from the earth. This is your signal that you’ve reached the main event.
The undisputed crown jewel of this trail is, of course, Jack’s Blowhole. However, don't arrive expecting a vertical geyser of water like you might see in a cartoon. This is a geological marvel on a much grander, more atmospheric scale.
A good-sized car park is available at the south end of Jack's Bay, which serves as the trailhead. Toilet facilities are located at the car park.

Out and back
Jack’s Blowhole is actually a massive collapsed sea cave. Millions of years of relentless ocean erosion carved out a subterranean tunnel from the sea, stretching a staggering 200 metres inland. Eventually, the roof of the cavern became too heavy and collapsed, creating a gaping abyss that is 55 metres deep, 144 metres long, and 68 metres wide.
Standing at the dedicated viewing platform, looking down into the sheer-sided chasm, is a humbling experience. It feels like looking into the very jaws of the earth. The best photo opportunities are from the short loop track that encircles the blowhole, allowing you to see the cavern from multiple angles.
Another highlight is the clifftop panorama. Because the blowhole is situated on a high point of the coast, the views from the surrounding cliffs are world-class. The contrast between the vibrant green of the farmland and the deep, moody blues of the Southern Ocean makes for incredible landscape photography.
Finding the trailhead is straightforward, making it a great addition to any Catlins road trip. From the main township of Owaka, head south on Pounawea Road and follow the signs for Jack’s Bay. It is approximately a 10 to 15-minute drive (about 10km) from the centre of Owaka.
The road eventually leads you to the southern end of Jack's Bay. You’ll find a good-sized gravel car park right at the trailhead. It’s well-maintained and usually has plenty of space, even during the busier summer months. Conveniently, there are toilet facilities located right at the car park, which is a good idea to use before you set off, as there are no facilities along the track or at the blowhole itself.
The Catlins is a haven for biodiversity, and the Jack's Blowhole Track is no exception. As you walk through the pockets of native bush and along the clifftops, keep your eyes and ears open for some of New Zealand’s most iconic birdlife.
If you gaze out toward the ocean or scan the rocks at the base of the cliffs, you might even spot some marine life. Oystercatchers are common along the shoreline with their distinctive bright orange beaks. While rare, keep a very quiet lookout for the Yellow-eyed Penguin (Hoiho) or the Little Blue Penguin returning to shore at dusk, though they are quite shy and should always be given plenty of space.
The beauty of the Jack’s Blowhole Track is that it is a year-round destination. Each season brings a different flavour to the walk:
The name "Jack’s Blowhole" carries a significant weight of local history. It is named after the legendary Ngāi Tahu chief, Tuhawaiki, who was a prominent leader in the early 19th century. To the early European whalers and settlers, he was known by the colourful nickname 'Bloody Jack'—not because of a violent nature, but because of his frequent use of the word "bloody" in his English speech.
Tuhawaiki was a formidable navigator and a respected leader who played a crucial role in the signing of the Treaty of Waitangi in the south. The nearby Tuhawaiki Island (visible from the track) also bears his name, serving as a permanent reminder of the deep Māori heritage of the region.
Geologically, the area is part of the Catlins Coast, which is world-renowned for its Jurassic-age rock formations. The blowhole itself is a spectacular example of how the relentless power of the Southern Ocean interacts with the coastal geology to create landscape features that are constantly evolving.
After an hour of coastal air and farm walking, you’ll likely have worked up an appetite. Head back toward the township of Owaka (about 10km away) to refuel.
For a classic Kiwi experience, stop in at the Catlins Cafe. This is a true local gem, famous among hikers for its wholesome, "soul food" style menu. If you’re visiting on a cooler day, their seafood chowder is legendary—creamy, packed with fresh ingredients, and perfect for warming your bones. It has a very cozy, welcoming atmosphere that makes you feel right at home.
Alternatively, if you’re looking for something a bit more substantial or a place to sit by a roaring fire, the Lumberjack Bar and Cafe is an excellent choice. With its timber and brick decor, it pays homage to the region's sawmilling history. They offer a comprehensive menu ranging from hearty burgers to local delicacies, making it a great spot for a post-hike celebration with friends or family.
Whether you are a seasoned hiker or just someone looking for a memorable detour on a road trip, Jack’s Blowhole Track offers a unique blend of natural power, cultural history, and stunning scenery that you won't soon forget.
