Old Reservoir Walk

Out and back

Highlights & Must-See Features

The absolute standout of this trail is, of course, the Old Reservoir itself. Reaching this historic site feels like stepping back into the 19th century. Built in 1875, this stone-lined structure is a fascinating relic of Cromwell’s early infrastructure. It was constructed out of necessity following a typhoid outbreak, serving as the primary water supply for the burgeoning gold-mining town. You can still see the original stone masonry, the old exit pipes, and even the depth-measuring posts. It’s a tangible, weathered link to the grit and determination of the region’s pioneers.

Beyond the history, the reservoir serves as a natural viewing platform. The 360-degree views from this height are unparalleled. You can trace the path of the Clutha and Kawarau Rivers, see the dramatic schist rock formations that define the geology of the area, and look down upon the Quartz-Reef Tailings—remnants of the intense gold-mining activity that once reshaped this entire valley.

For those who aren't quite ready to head back down, there is an option to extend the adventure. A 2.3-kilometre loop track continues past the reservoir, climbing even higher before looping back to the road. This section is a bit more rugged and traverses some stunning rocky outcrops, perfect for anyone wanting a slightly more "off the beaten path" feel.

Getting There

Finding the trailhead is straightforward. The walk starts from the Bruce Jackson Memorial Lookout car park, which is located directly on State Highway 8, just a few minutes’ drive from the centre of Cromwell.

The car park is spacious and offers plenty of room for visitors, though it can get busy on sunny weekend afternoons. A word of caution: to reach the start of the track, you will need to cross the state highway. This is a high-speed zone, so please take extra care, especially if you have children with you. Once you are across the road, the track is clearly marked and easy to follow.

Wildlife Spotting

While the landscape might look arid and quiet at first glance, the Old Reservoir Walk is home to a surprising variety of birdlife. The hardy vegetation provides a great habitat for native species that have adapted to the dry conditions.

Keep your eyes peeled for the cheeky Pīwakawaka (Fantail), which will often follow hikers to snack on the insects stirred up by their footsteps. You’ll also likely hear the melodic call of the Korimako (Bellbird) or the delicate "stitch-stitch" of the Riroriro (Grey Warbler) echoing from the scrub.

If you are particularly lucky, look to the skies for the New Zealand Falcon (Kārearea). These majestic birds of prey are occasionally seen soaring above the Cromwell Basin, using the thermals to hunt. Unlike the more common harrier hawk, the Kārearea is smaller, faster, and much rarer—a true treat for any wildlife enthusiast. You may also spot Paradise Shelducks (Pūtangitangi) near the water's edge or hear the constant song of Skylarks high above the tussocks.

Seasonal Magic & Practical Tips

Cromwell is a land of extremes, and the Old Reservoir Walk changes dramatically with the seasons.

• Spring: This is perhaps the best time to visit. The hills are at their greenest, the air is fresh, and the wild thyme begins to bloom, painting the hillsides with a subtle purple hue.
• Summer: It gets hot—very hot. Central Otago frequently records the highest temperatures in the country. If you’re walking in summer, start early in the morning to avoid the midday sun. There is very little shade on this trail.
• Autumn: The "Golden Season" in Otago is legendary. While the hills remain tawny, the trees in the Cromwell township and the Heritage Precinct below turn vibrant shades of yellow and orange, creating a stunning contrast with the blue of Lake Dunstan.
• Winter: Expect crisp, clear days. The trail can be frosty in the mornings, but the views of the snow-capped Pisa Range are spectacular.

• Water: There is no drinking water on the trail, and the dry air can dehydrate you faster than you think.
• Sun Protection: The Central Otago sun is fierce. Wear a hat and apply plenty of sunscreen, even on cloudy days.
• Footwear: While the track is easy, it is gravelly. A pair of sturdy trainers or walking shoes with good grip is recommended.
• Camera: You’ll definitely want to capture the vista from the reservoir!

Note on Dogs: Please leave your furry friends at home for this one, as the trail is not dog-friendly. This helps protect the local wildlife and respects the surrounding land.

Local & Regional Context

The area surrounding the Old Reservoir Walk is steeped in stories. Long before the first Europeans arrived, Māori used the Clutha River (Mata-Au) as a seasonal highway for gathering pounamu (greenstone) and hunting moa. The dry, rocky landscape was a challenging but vital part of their seasonal migrations.

In the 1860s, the discovery of gold changed everything. Cromwell became a bustling hub, and the landscape was transformed by miners. The Quartz-Reef Tailings you see from the lookout are a reminder of the massive scale of these operations. Later, in the early 1990s, the valley underwent another massive change when the Clyde Dam was completed, flooding the old town of Cromwell and creating Lake Dunstan. Standing at the Old Reservoir, you are essentially looking down at a landscape that has been "re-written" multiple times over the last 150 years.

After the Walk

Once you’ve made your way back down the hill, you’ll likely be ready for some refreshments. Luckily, Cromwell has some of the best spots in the region to refuel.

If you’re after a world-class caffeine hit, head over to Fusee Rouge Cafe (4.7km away). Voted the best cafe in New Zealand in 2022, it’s famous for its quirky vibe and incredible baked goods. Their breakfast options are the stuff of legends—perfect if you did an early morning hike.

For a more historic atmosphere, drive down to the Cromwell Heritage Precinct and visit the Grain & Seed Cafe. It’s located in a beautifully restored building with views directly over the lake. It’s a fantastic spot to sit outside and soak in the sun. If you’re looking for something a bit stronger, the Penny Black Bar in the same precinct offers craft cocktails and local Otago wines with a waterfront view.

If you have the family in tow, the Five Stags Cromwell is a great, welcoming pub with a big garden bar and hearty meals. It’s the perfect place to relax and chat about the day’s adventure.

The Old Reservoir Walk might be short, but it offers a deep connection to the heart of Central Otago. It’s a walk that rewards every step with a story, a scent, or a view that you won’t soon forget.
