There is a bird in New Zealand that sounds exactly like R2D2. Among the competing chirps and trills of the rainforest, the bleeps and bloops of the tui, a small dark bird with the white collar of a priest, interrupted with perfect comedic timing. I found it impossible not to smile every time I heard it — and over the course of a week in New Zealand’s West Coast region, I heard it often. Soon, it started feeling like a familiar friend. On long solo hikes, soaked through with rain, calves burning, I heard the tui, beckoning me around the next bend where some new sight would undoubtedly leave me breathless.

When I arrived on the West Coast, a 370-mile strip of land on New Zealand’s South Island, there was an omnipresent buzz about the opening of a new hiking trail.

The Paparoa Track is the 10th of the New Zealand Great Walks, multiday treks overseen by the Department of Conservation that cut through protected mountains, forests and valleys. In all it is 34 miles long and can be completed in three days by foot or two on a mountain bike. Three huts are placed at intervals along the trail, which cuts through Paparoa National Park, passing river gorges, up onto mountain ridges that overlook the sea and through dense primeval rainforests. So intense is the excitement around its opening that the huts are mostly booked solid through March.

While the Paparoa Track is the first new Great Walk in 25 years, it is not as if the South Island is lacking in natural grandeur. On my drive to the West Coast, I could barely get through a single song on the “Lord of the Rings” soundtrack (I mean, what else would I be listening to?) without hitting another viewpoint so beautiful I had to stop. Google Maps says the drive from Christchurch across the island to Greymouth should take about three hours. It took me seven.

The beauty began almost immediately outside Christchurch as the wide open pastures revealed the snow-capped peaks of the Southern Alps. In the blinding light of a clear noon sky, they seemed to sparkle. The road began to curve as I reached the mountain range’s foothills, where towering rock formations hinted at what was to come. I hit Arthur’s Pass, a former gold rush outpost surrounded by beech forests and thundering waterfalls. I kept driving. Water that looked like spilled cyan paint rushed along river beds made from smooth, multicolored stones. Mist clung to dew-sprinkled forests that grew down steep inclines. With the exception of the two-lane road and the power lines that ran along it, the terrain seemed entirely untouched by civilization.

Eventually, I reached Greymouth, my base to explore the Paparoa Track and the greater West Coast region. Greymouth, known to the Maori long before Europeans arrived as Mawhera, has seen better days. Once a hub for coal and gold mining, today it feels like a time warp to the 1970s, when the boom started to run out. The regal facades of once grand hotels are peeling, their innards carved out and abandoned. The streets are empty — by 8 p.m. it was as if I were the town’s only resident.

From Greymouth it was a short drive up the stunning Great Coast Road to Punakaiki, where I came across the only tour buses I saw in a week. The crowds — myself included — were there to see the Pancake Rocks, 30-million-year-old limestone formations that look like stacks of flapjacks, jutting out of the turbulent sea and creating pockets of air that send ocean spray shooting into the sky.

When I arrived, the Paparoa Track was still days from opening. But I was able to get a sneak preview of it, meaning I covered about 6 miles — or 17% — of the whole journey. After traveling through a landscape dominated by alpine forests and craggy peaks, it was jarring to head into the dense rainforest of Paparoa National Park. I couldn’t make sense of the terrain’s quick transition. Prehistoric ferns the size of golf umbrellas stretched over the dirt and stone paths and smaller ferns stood coiled, ready to spring to life. Mushrooms grew on the roots of trees felled by passing storms. The path sloped upward until it offered views of the Pororari River far below.

From Paparoa National Park I made my way south, following the Great Coast Road until it became the Glacier Highway and the terrain changed again, from the wet rainforests of the coast to steep mountains. I stopped in Hokitika, a far livelier town than Greymouth, famous for a gorge cut through with that same bright blue water I had been seeing everywhere, and for its jade-carving industry. Most of the shops selling New Zealand jade in town have open workshops, so I watched as carvers turned raw blocks of jade into twisting, glistening creations full of Maori symbolism.

Eventually, following the road south, I reached Franz Josef, a small town at the foot of a glacier of the same name. Dense clouds obscured the highest mountain peaks, but following a trail through the woods I walked until I came right to the glacier. Just under the shroud of gray, I could make out its tongue, thick ice blue with age. Since 2008, the glacier has retreated by about 2,600 feet, and rivulets of meltwater cutting through gray rock clearly show its once extensive reach.

I decided to change things up for my return trip to Christchurch and take the five-hour TranzAlpine train back to Christchurch, widely considered to be one of the most scenic train trips in the world. Tall windows ensure everyone has a view, and from an open-air viewing car in the back you can take photos without the glare of window panes.

Watching the landscape pass by, like a flipbook of postcards, I realized what was so special about New Zealand. There’s the environment, of course; it can feel like you’ve traveled to Hawaii, Ireland, Norway and the Azores over the course of a single day. But it’s also how New Zealanders interact with their environment. Around 86% of the land in the West Coast region is protected by the Department of Conservation. Most of the tourists I encountered were locals, out for weekend family trips to hike, camp and picnic. The Paparoa Track was finally opening after being funded by tax dollars and blessed by the local Maori population. This is a place that has been given a disproportionate serving of natural splendor and people here recognize its value. Honoring it is a national pastime.

By the time I reached Christchurch, I was rejuvenated. Despite the wear of daily hikes and inclement weather, I felt better rested than I have in a long time. Nature, unleashed like it is on the South Island of New Zealand, has the power to reset your entire being.

IF YOU GO: NEW ZEALAND

>> Don’t expect luxury when it comes to accommodations. Many tourists opt to rent camper vans and take advantage of New Zealand’s “freedom camping” laws that make it easy to find a place to park for the night. Just make sure you’re familiar with the rules around waste disposal and off-limits areas before you set off.

>> New businesses are springing up close to the Paparoa Track trailheads to cater to hikers and mountain bikers. I previewed one, the family-run Punakaiki Beach Camp, which is building new cabins and has a new shuttle to transport cyclists to and from the trail. Like the huts on the track ­itself, these places are filling up fast so be prepared to plan ahead.

>> While Greymouth isn’t the most inspiring home base for exploring the West Coast region, it’s worth making a stop at Monteith’s, a large, airy brewery with excellent food and even better ales.
