Jack's Blowhole Track

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.

Getting There

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.

Wildlife Spotting

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.

• Fantail (Pīwakawaka): These friendly little birds are almost guaranteed companions. They often flutter around hikers, catching the insects stirred up by your footsteps.
• Tūī and Bellbird (Korimako): Listen for the complex, melodic chiming of the Tūī and the clear, bell-like notes of the Bellbird coming from the forested gullies.
• New Zealand Pigeon (Kererū): You might hear the heavy "whoosh-whoosh" of wings before you see them. These large, iridescent green and white pigeons are occasionally seen perched in the ngaio trees.
• Australasian Harrier (Kāhu): Look up to see these large birds of prey soaring effortlessly over the farmland, using the coastal thermals to hunt.

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.

Seasonal Magic & Practical Tips

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:

• Summer: Offers the most settled weather and long daylight hours, perfect for a late afternoon stroll when the sun begins to dip.
• Autumn & Spring: These are fantastic times for birdwatching and enjoying the lush, green vibrancy of the farmland.
• Winter: Don't rule out a winter visit! While it can be chilly, the "roaring forties" winds often bring rougher seas, which is exactly what you want if you want to see the blowhole at its most dramatic.

• Check the Tides: To see the blowhole performing at its best, try to time your visit for high tide or during a period of heavy swell. This is when the waves are forced through the tunnel with the most power, creating the loudest booms and the most impressive spray.
• Timing: Early morning or late afternoon provides the softest light for photography and the best chance for bird activity.
• What to Wear: The Catlins is notorious for its "four seasons in one day" weather. Even on a sunny day, the coastal wind can be biting. Bring a windproof jacket, sturdy walking shoes (the track can get a bit muddy after rain), and plenty of sun protection.
• Water & Snacks: There is no drinking water on the trail, so bring a bottle with you.

Local & Regional Context

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 the Walk

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.
