Waimate District

If you find yourself cruising through the sun-drenched landscapes of the Waitaki Valley, it is easy to be mesmerised by the vast, turquoise expanses of Lake Benmore and Lake Aviemore. However, tucked away just off the main road lies a hidden gem that many travellers—and even some locals—completely miss. The Deep Stream Track is a captivating, short adventure that takes you deep into a "flooded canyon," offering a unique perspective on the rugged beauty of the Waimate District.
Whether you are a seasoned hiker looking for a quick leg-stretch or a family seeking a picturesque spot for a weekend outing, this 4km return journey provides a genuine sense of discovery. It is a walk that rewards curiosity, leading you through narrow rocky passages and native shrublands to a tranquil lakeside finish.
The journey along the Deep Stream Track is one of constant change. From the moment you step off the gravel pull-off near Te Akatarawa Road, you feel as though you are entering a secret world. The trail is an "out and back" route that sidles along the steep faces of a canyon that was partially submerged when the Aviemore Dam was commissioned in the 1960s. This "flooded" nature gives the stream a deep, still, and almost ethereal green quality that contrasts beautifully with the rugged, sun-baked rock of the valley.
The terrain is moderate, mostly following a well-defined path that has been beautifully benched into the hillside. In the steeper sections, you will find sturdy wooden steps that help with the elevation gain of approximately 200 metres. However, don't let the short distance fool you; the track can be quite narrow in places. As you wind your way along the canyon wall, there are occasional steep drop-offs down to the water below. While this adds to the "adventure" feel of the walk, it’s something to keep in mind if you are hiking with younger children.
The path itself is often dry and gravelly, a characteristic of the North Otago climate. This can make the surface a bit "ball-beany" and slippery underfoot, particularly during the height of summer. You’ll want to watch your footing as you navigate the bends. About 20 minutes into the walk, the trail opens up to reveal a perfectly placed picnic table. It’s an ideal spot to catch your breath and soak in the silence, broken only by the lap of water against the rocks and the occasional call of a native bird.
Access the Deep Stream Track by turning off State Highway 83 at Aviemore Dam onto Te Akatarawa Road. There is a small pull-off area suitable for 2-3 cars on the lakeside of the road, just past a small bridge. Look for a small sign, which can be easy to miss if you're not paying close attention.

Out and back
As you continue past the halfway point, the canyon begins to widen, and the rugged rock faces give way to a softer landscape. The track eventually concludes at the stream delta. Here, the atmosphere shifts entirely as you find yourself standing under the dappled shade of majestic willow trees. It is a peaceful, secluded spot where the stream meets the lake, perfect for a quiet moment of reflection or a bit of lakeside fishing before you turn around to head back the way you came.
What makes the Deep Stream Track truly special is its botanical diversity. This isn't your standard pine forest or grassy paddock walk; it is a sanctuary for some of New Zealand’s rarest flora. Keep an eye out for the prostrate kōwhai (Sophora prostrata). Unlike its more common cousin that grows into a tall tree, this variety stays low to the ground with a tangled, wiry habit. If you visit in late winter or early spring, you’ll see it burst into a brilliant display of golden-yellow flowers.
Botanists and nature lovers should also look for two very rare species of native broom: Carmichaelia curta and Carmichaelia kirkii. These plants are specialists in this dry, rocky environment and are a testament to the unique microclimate of the Waitaki Valley.
The geological scenery is equally impressive. The way the deep green waters of the stream carve through the greywacke rock creates a dramatic, moody aesthetic that is a photographer’s dream. The "flooded canyon" effect means you are often looking straight down into deep water from the trail, providing a perspective you don’t often get on inland New Zealand hikes.
Locating the trailhead requires a bit of an eagle eye. From State Highway 83 (the main road running through the Waitaki Valley), turn onto the Aviemore Dam and cross over to Te Akatarawa Road. Follow this road along the lakeside for a short distance.
Just past a small bridge, you will see a small pull-off area on the lakeside of the road. It’s quite modest, with only enough room for about 2 or 3 cars, so it pays to arrive early during the busy summer months. Look for the small Deep Stream Track sign—it’s easy to overshoot if you’re moving too fast! If the parking area is full, please ensure you park safely off the road to allow local traffic and boat trailers to pass.
The Waitaki Valley is a haven for birdlife, and the Deep Stream Track is no exception. Because the track is surrounded by native scrub and is close to the water, you get a mix of forest and aquatic species.
The Deep Stream Track is a true four-season trail, with each time of year offering something different:
The Waitaki area is steeped in history. For Māori, the Waitaki River was a vital ara tawhito (ancient trail) and a source of mahinga kai (food gathering). The name Waitaki translates to "the tears of Aoraki," referencing the glacial meltwaters that feed the river system from the Southern Alps.
In more recent history, the landscape was transformed by the massive Waitaki Hydroelectric Scheme. The creation of Lake Aviemore in 1968 drowned parts of the original Deep Stream, creating the unique "flooded canyon" environment you see today. Walking this track is a way to see the intersection of natural history and human engineering—where the rugged, ancient rock meets the man-made lakes that power much of New Zealand.
After a couple of hours exploring the canyon, you’ll likely be ready for some refreshments. Fortunately, you’re in a great part of the country for a post-hike treat.
The Deep Stream Track may be short, but it packs a significant punch. It offers a sense of solitude and natural beauty that is hard to find so close to a main highway. Next time you're passing through the Waimate District, take the turn-off at Aviemore Dam—you won't regret discovering this Waitaki secret.
