Londonderry Rock Walk

Out and back

The undisputed crown jewel of this walk is, of course, the Londonderry Rock. Calling it a "rock" feels like a bit of an understatement—it is more like a stone skyscraper. Standing eight metres tall and weighing somewhere between 3,000 and 4,000 tonnes, this massive boulder is what geologists call a "glacial erratic."

Thousands of years ago, during the last ice age, a massive glacier transported this rock from the mountains and deposited it here as the ice retreated. It sat undisturbed for millennia until the Kumara gold rush of the 1880s brought miners to its base. The story goes that the miners attempted to move it or break it apart to reach the gold-bearing gravels beneath it. However, the rock lived up to its reputation of being "stubborn as the land itself." It was simply too large to budge, even for the most determined prospectors. They eventually gave up and worked around it, leaving it as a permanent monument to nature’s immovable power.

Today, the rock is a fantastic photo opportunity. Standing at its base makes you feel incredibly small, and it serves as a tangible link between the ancient geological forces of the West Coast and the human endeavour that followed. For kids, it’s a source of wonder—a giant’s marble left behind in the woods.

Getting There

Finding the trailhead is straightforward, making it a perfect pit-stop on a road trip. The Londonderry Rock Walk is located approximately 1km east of the township of Kumara.

If you are travelling on State Highway 73, look for the signposted turn-off onto a metalled (gravel) road. This short access road runs alongside an old water race—another relic of the mining era used to transport water for sluicing. Follow this road to the very end, where you will find a designated parking area. The trail is clearly signposted from the carpark, ensuring a stress-free start to your adventure.

Wildlife Spotting

Despite being a short walk, the dense native bush is a haven for New Zealand’s feathered locals. The forest here is alive with song, and if you move quietly, you are almost guaranteed some close encounters.

• Tūī (Common): You’ll likely hear their complex melodies and metallic "clunks" before you see them. Look for the white tuft under their chins high in the canopy.
• Kererū (Common): The heavy "whoosh-whoosh" of wings usually gives away the New Zealand wood pigeon. These large, iridescent green and white birds love the berries in this area.
• Fantail / Pīwakawaka (Common): These friendly little birds are almost certain to follow you along the path. They flit around hikers to catch the tiny insects disturbed by your footsteps.
• Weka (Occasional): Keep an eye on the forest floor. These flightless, cheeky birds are known for their curiosity (and their tendency to try and steal shiny objects!).
• Bellbird / Korimako (Occasional): Listen for their clear, bell-like notes that often blend with the Tūī song.

Tip: The best time for birdwatching is early morning or late afternoon when the forest is most vocal. However, because the walk is so short and the bush so lush, you’ll likely see a Pīwakawaka no matter what time you visit.

Seasonal Magic & Practical Tips

The Londonderry Rock Walk is truly a year-round destination. Because there is no elevation gain and the track is well-maintained, it doesn't suffer from the snow or dangerous ice that affects higher-altitude alpine tracks.

• Spring: This is when the forest is at its most vibrant. The mosses are lush from spring rain, and the birds are particularly active and vocal.
• Summer: The deep shade of the native bush provides a cool sanctuary from the West Coast sun. It’s a great "low-effort" activity for hot days.
• Autumn & Winter: The West Coast is often stunning in winter, with crisp, clear days. The dampness of the season only adds to the "magical forest" atmosphere, making the lichen and fungi pop with colour.

• Footwear: While it’s a flat walk, the West Coast is notoriously damp. Comfortable walking shoes or sneakers with decent grip are fine, but expect a bit of mud if it has been raining recently.
• Rain Jacket: This is the West Coast—the "Wet Coast." Even if the sun is shining, a light raincoat is a must-carry.
• Insect Repellent: The West Coast sandfly is a legendary local. They aren't too bad in the deep bush, but you’ll be glad you have repellent if you stop for a long photo session at the rock.
• Water: It’s a short walk, but it’s always good practice to have a bottle of water in the car.

Local & Regional Context

To walk this trail is to walk through the heart of West Coast history. The nearby town of Kumara was once one of the most prosperous gold-mining settlements in New Zealand. It was also the home of Richard "King Dick" Seddon, one of New Zealand’s most famous and longest-serving Prime Ministers.

The area is also significant for its proximity to the Lake Kaniere Scenic Reserve. While the Londonderry Rock is a quick visit, it acts as a gateway to the wider region's wonders. The geology here—the mixture of glacial debris and gold-rich gravels—is what defined the settlement of the coast. For Māori, the West Coast (Te Tai Poutini) was, and remains, the source of precious Pounamu (greenstone), and the ancient trails used to transport this stone often crossed through these very forests.

By visiting the Londonderry Rock, you aren't just looking at a big stone; you are standing at a crossroads of geological time and human ambition.

After the Walk

Once you’ve finished your stroll and snapped your photos of the great erratic, you’ll likely be looking for a spot to refuel. Luckily, Kumara is home to some fantastic hospitality.

• Kumara Hotel (5km away): You cannot visit this area without stopping at the historic Kumara Hotel. This beautifully restored pub offers a classic "Kiwi" atmosphere with plenty of gold-rush charm. It is the perfect place for a hearty pub meal or a cold drink. The walls are lined with local history, making it feel like a continuation of your walk.
• Kumara Junction Cafe & Bar (9km away): If you are heading back toward the main highway junction (SH6 and SH73), this is a very convenient stop. It’s a great spot for a quick coffee, a slice of cake, or a more substantial lunch before you continue your journey up or down the coast.

The Londonderry Rock Walk is a reminder that you don't need to climb a mountain to find something extraordinary. It’s a quick, easy, and deeply rewarding peek into the soul of the West Coast.
