Moria Gate Arch Track

Loop

As the loop continues and you cross over the top of the arch, keep your eyes on the ground. You will find paving stones embossed with the footprints of the extinct moa. These prints are a poignant and powerful reminder of the giant birds that once roamed these very forests. It’s a fantastic photo opportunity and a great way to spark a conversation about New Zealand’s unique natural history.

Finally, don't miss Mirror Tarn. This small, tranquil lake is famous for its incredible reflections. On a calm day, the surrounding rainforest is mirrored so perfectly in the dark, still water that it’s hard to tell where the forest ends and the lake begins.

Getting There

To find this hidden gem, you’ll first need to get to Karamea. From the Karamea township, head north for about 10 km until you reach the turn-off for McCallums Mill Road.

A word of caution: This is where the adventure truly begins. McCallums Mill Road is a 13-14 km gravel road that is narrow, steep, and unsealed. It is a slow drive, and we recommend a speed limit of 30 km/hr to stay safe. Because of the tight turns and a 2.8-metre height restriction barrier, this road is generally not suitable for large motorhomes or high-top campervans.

Once you arrive at the main Ōparara car park, you’ll find plenty of parking, toilet facilities, and an information shelter to help you get your bearings before you set off.

Wildlife Spotting

The Ōparara Basin is a haven for some of New Zealand’s most iconic and rare species. Because the area is so remote and well-preserved, the birdlife is spectacular.

• Whio (Blue Duck): These rare ducks love fast-flowing, clean water. If you are quiet as you approach the river near the arch, you might spot them bobbing in the current.
• Kakaruai (South Island Robin): These are the friendly "conductors" of the forest. They are very curious and will often hop right up to your boots to see if you’ve stirred up any tasty bugs.
• Weka: These cheeky, flightless birds are common here. Keep a close eye on your bags if you stop for a snack!
• Powelliphanta (Giant Land Snails): Keep an eye on the track itself, especially after rain. These snails are huge (some the size of a man’s fist) and are highly protected. Please watch your step so you don't accidentally crush one.

Seasonal Magic & Practical Tips

The Moria Gate Arch Track is a fantastic destination year-round, but each season offers something different:

• Spring & Summer: The forest is at its most vibrant, and the birdlife is very active. It’s the best time for spotting whio ducklings.
• Autumn & Winter: The West Coast can be misty and moody, which only adds to the "Lost World" atmosphere of the basin. The reflections at Mirror Tarn are often at their best on crisp, still winter mornings.

• Insect Repellent: This is West Coast sandfly territory. Do not forget your repellent, or you’ll spend the whole walk swatting!
• Sturdy Footwear: While the track is easy, it can be slippery when wet. Good sneakers or light hiking boots are recommended.
• Rain Jacket: This is a rainforest, after all. Showers can blow in quickly, even on a sunny day.
• Water & Snacks: There are no shops out at the basin, so pack enough to keep you going.

Local & Regional Context

The geology of the Ōparara Basin is truly world-class. The limestone here was formed over 35 million years ago from an ancient seabed. Over millions of years, the relentless flow of the Ōparara River carved out the intricate cave systems and massive arches we see today.

Culturally, the area is part of the deep history of the West Coast (Te Tai Poutini). While the arches themselves are a geological marvel, the basin is also a site of immense paleontological importance. The caves in this region have yielded some of the richest deposits of sub-fossil bird bones in the country, helping scientists understand the world of the moa and the Haast’s eagle.

After the Walk

By the time you’ve finished the loop and driven back down the gravel road, you’ll likely have worked up a healthy appetite. Luckily, Karamea has some fantastic spots to refuel:

• Vinnie’s Coffee and Paninis: Located at Market Cross, this is the perfect first stop. They serve locally roasted organic coffee and fresh homemade pies—exactly what you need after a morning in the bush.
• The Last Resort: This is a bit of a local institution. It has a lovely relaxed atmosphere and beautiful gardens. If you’re visiting during the right season, try their local whitebait delicacies—it doesn’t get more West Coast than that!
• Karamea Village Hotel: If you’re after a classic Kiwi pub experience, head here. It’s a historic hotel with an award-winning restaurant serving honest, home-cooked meals that are perfect for a post-hike celebration.

The Moria Gate Arch Track is more than just a walk; it’s a chance to connect with an ancient version of New Zealand. It’s easy, beautiful, and filled with surprises around every corner. Just remember to watch out for the snails and keep your camera ready for those moa prints!
