The Manuherikia and Ida Valleys – Gold, Water, and Horizons
Tucked between Otago’s highest ranges, the Manuherikia and Ida Valleys provide a road trip through contrasting basins of golden grass, dramatic reservoirs, old gold workings, engineering heritage and hills strewn with rocky tors. Connected by the Ida Valley–Omakau Road and SH85, these valleys form a perfect loop from Omakau, ideal for a weekend escape at any time of year.
In summer, the landscape is dry and sun-soaked, with long days and piercing blue skies. In winter, the high elevations bring snow-dusted ridges and crisp air, a completely different kind of beauty.
Lower Manorburn: Rock Ridges and Quiet Water
From Alexandra, head up to Lower Manorburn Dam, nestled in a schist amphitheatre of dry ridges and big skies. It’s part of the historic Galloway irrigation scheme, though today it feels like a forgotten gem.
Walk across the reserve to the dam itself, where water can spill in dramatic cascades. Nearby, a short climb leads to a bluff with dramatic views over the lake — made slightly more thrilling by the broken-down fence! It’s a great picnic spot, and trout fishing is popular in season.
Ōmakau – Rail Trail Hub and Dark Skies
Ōmakau is the next stop on the highway, sitting at the meeting of the Otago Central Rail Trail, the Manuherikia River, and the road to the Ida Valley. It’s a small but welcoming settlement, with accommodation, a historic pub, and a strong link to Central Otago’s farming history.
Just over the bridge lies Ophir, with its heritage stone buildings and the 1880s suspension bridge, still drivable. Although not a formal dark sky reserve, this area provides superb nighttime stargazing on clear nights.
Ida Valley Drive: Over the Ridge into Wide Open Space
From Omakau, take Ida Valley–Omakau Road, a beautiful cross-country drive over Rough Ridge, descending into the broad, open Ida Valley. There are two superb viewpoints next to the road. The contrast is striking: soft light, pale gold grasslands, and a sky that feels twice as wide.
This is part of the route of the historic Old Dunstan Road, once the main pack route from Dunedin to the goldfields. Today, it’s a highway with access to remote reservoirs, historic trails and inventive heritage.
Poolburn Reservoir: Tors, Tussock and Trout
Detour up the gravel road to Poolburn Dam on a surviving section of the Old Dunstan Road, to discover a Depression-era concrete structure set high in a rocky basin. It’s a place of wind-blown tussock, schist tors, and moody reflections, famously featured in The Lord of the Rings.
Fishing is popular (mainly brown trout), and the rough, remote road has fantastic views. In dry conditions, most vehicles can make it, just allow time and avoid wet weather.
Oturehua & Hayes Engineering: Innovation and Trail Vibes
Back in the heart of the Ida Valley, Oturehua is a laid-back village with a big story. It’s home to the Hayes Engineering Works, where Ernest Hayes invented tools that transformed farming across New Zealand. The original workshop, powered by belts and pulleys, still runs on open days.
Nearby, you’ll find the Gilchrists Store, stocked since 1899 and part general store, part museum. The town is a favourite Rail Trail stop, with cafés, trail services and seasonal events.
Golden Progress Mine & Idaburn: Poppet Heads and Ice
Just east of Oturehua, walk 10 minutes from the roadside to the Golden Progress Mine, where Otago’s only surviving poppet head stands tall above the schist terraces. Two rusted boilers and relics remain from the quartz mining days.
In winter, the nearby Idaburn Dam occasionally freezes hard enough for curling. In summer, it’s a quiet spot for a picnic or an evening drive under Ida Valley’s epic sky.
Falls Dam: Gorge Views and Wild Water
Drive northeast into the head of the Manuherikia Valley to reach Falls Dam, built in the 1930s and still essential for irrigation and hydro. The view from the road is spectacular as the Manuherikia River plunges into a narrow gorge surrounded by golden hills.
Don’t miss the circular overflow drain, which forms a swirling whirlpool when the lake is full. This is a good picnic stop in good weather and a chance to see Otago’s high country water engineering up close.
St Bathans: Blue Lake and Gold Tailings
Wrap up your loop with a detour north to St Bathans, a near-perfect gold town frozen in time. The Blue Lake, once a deep gold claim, now shines electric blue against white cliffs — a stunning contrast created by sluicing and tailings.
The Vulcan Hotel, reputedly haunted, offers food, drink and heritage charm. A short walking track leads around the lake, with views to the Dunstan and Hawkdun Ranges, especially magical at dusk or after snow.

Hints for Travellers
Is this road trip suitable year-round?
Yes: the loop is beautiful in all seasons. Summer has golden hills, dry roads and warm weather, while winter brings crisp air, frosty mornings and the chance of snow on higher elevations like Poolburn and Rough Ridge. Generally, the roads will still be clear, including the rougher gravel options, but stay weather-aware.
What kind of vehicle do I need?
The entire trip is accessible by 2WD in good conditions, but Poolburn Reservoir and Falls Dam involve gravel roads, so take care after rain or snow. Drive slowly and check conditions before setting out.
Are facilities available?
Towns like Omakau, Ophir and Oturehua have excellent pubs and cafés, fuel and basic supplies. St Bathans has a pub and seasonal services. Carry snacks, water and fuel if exploring off the main routes or in quiet seasons.
What can I do besides sightseeing?
The route connects to the Otago Central Rail Trail for cycling, and many areas allow trout fishing (in season — Oct to April). There are also picnic areas, short walks, and interpretive panels at key sites such as Hayes Engineering and Golden Progress Mine.
Where can I stay?
Accommodation is available in Omakau, Ophir, Oturehua and St Bathans — including lodges, B&Bs, campgrounds and Rail Trail lodgings. Book ahead during summer or public holidays.
Are these places family-friendly?
Yes. Many stops are suitable for kids, with space to explore, learn local history, and enjoy nature. Just supervise near cliffs, water, and old mining sites, as some are unfenced or rustic.
Are dogs allowed?
Dogs are allowed in most areas but should be kept on a lead, especially near farmland and conservation areas. Check local DOC or council guidelines where posted.
What’s the best way to link this loop into a longer trip?
This loop connects easily to Alexandra, Clyde, Ranfurly, or Lawrence. It can be extended into the Maniototo and Danseys Pass for a multi-day journey across Central Otago’s gold and rail heritage routes.
