Karangahake Gorge: a family walk through gold-mining country
Karangahake Gorge sits on State Highway 2 between Paeroa and Waihi, at the southern gateway to the Coromandel. It's a deep, bush-clad canyon where the Ohinemuri River runs green and fast, and where the hills are still full of the tunnels, tramways and stone foundations left behind by one of New Zealand's biggest gold rushes. In the late 1800s and early 1900s this was serious mining country: the Talisman and Crown companies worked the rock here, and the whole valley hummed with batteries crushing quartz around the clock.
What makes it such a good day out now is that most of the walking is flat, easy and free. You can wander old mine tunnels, cross swing bridges over the river, duck through a long lit railway tunnel and cool off at a waterfall, all without a steep climb in sight. It suits families with young kids, casual walkers and anyone who wants a bit of history with their fresh air. Here's how to make the most of it.
What Karangahake Gorge actually is
The gorge is a slice of the old Paeroa-to-Waihi railway line and goldfield, now looked after mostly by the Department of Conservation. The tracks follow the river and the former rail formation, so they're generally level and well-formed. Along the way you'll pass the remains of the Talisman and Crown mines, concrete and stone ruins slowly being reclaimed by bush, and interpretation panels that explain what you're looking at.
You don't need to do a big loop to enjoy it. Plenty of people just walk in for twenty minutes and turn around. But the Windows Walk and the rail tunnel are the two things most people come for, and both are worth the effort.
The Windows Walk (bring a torch)
Bring a torch
The Windows Walk runs through old mine tunnels that are genuinely dark between the window openings. Everyone needs a torch or headlamp. Watch children near the window openings and on the bridges.
This is the highlight and the one to prioritise. The Windows Walk threads through old mine tunnels cut straight into the cliff face, and every so often the rock opens up into a "window" looking straight down onto the Ohinemuri River far below. There are four of these openings, and they're the reason for the name. Between the windows the tunnels are genuinely dark, so a torch or headlamp is essential for everyone in your group. Phone torches will get you through, but a proper headlamp is much better as it leaves your hands free on the uneven, sometimes damp ground.
The walk passes relics of the Talisman and Crown mining operations, and there are short side tunnels and an old underground pumphouse you can poke into if you've got a light. Watch children carefully near the window openings and on the bridges. The full Windows loop takes roughly an hour return at a relaxed pace. It's rated easy, though the tunnel floors are rough and uneven, so wear closed shoes with grip. Dogs aren't allowed on the Windows Walk.
The long railway tunnel
Downstream from the main car park is the old railway tunnel, about 1.1 km long, driven right through the hill. Unlike the mine tunnels it's lit, so you can walk the whole thing and see the walls curving away ahead of you, with daylight at each portal and swing bridges over the river at both ends. It's a wide, flat, cool walk and a real hit with kids. Even though it's lit, the light is dim in the middle, so a torch or bike light still helps and is recommended, especially if you're cycling through.
Other walks and loop options
| Walk | Return time | Difficulty | Highlight |
|---|---|---|---|
| Windows Walk | ~1 hr | Easy (dark tunnels) | 4 windows over the river · torch! |
| Rail tunnel loop | <1 hr | Easy, flat | 1.1 km lit railway tunnel |
| Historic Walkway (to Waikino) | Varies | Easy, flat | River, mining ruins, swing bridges |
You can string the tunnels, bridges and ruins together into a few different loops depending on how much time you have. A short rail-tunnel loop from the Karangahake car park takes under an hour and stays flat. Combining the Windows Walk with the rail tunnel makes a two-to-three-hour outing that covers most of the best bits. For a longer walk, the Karangahake Gorge Historic Walkway runs along the river between Karangahake and Waikino and can be walked as far as you like before turning back.
A word of caution: the lower Crown Track and Crown Tramway sections have been closed at times because of large landslips, and parts of the gorge and Hauraki Rail Trail have been affected by storm damage. These tracks also close during and after heavy rain for safety. Always check the DOC website and the Hauraki District Council pages for current track status before you go, especially after a wet spell, so you're not turned back at a barrier.
Owharoa Falls and swimming holes
Owharoa Falls, near Waikino, is an easy stop and one of the prettiest waterfalls in the area, tumbling over wide rock terraces. It's a very short walk from a small roadside car park, so you can see it even without a long day out. The pool at the base and various spots along the Ohinemuri are popular swimming holes in summer. The river can run cold, fast and high after rain, so pick a calm, obvious swimming spot, keep a close eye on children, and don't go in when the water is up or discoloured.
Cycling the Hauraki Rail Trail
The gorge is one of the most popular sections of the Hauraki Rail Trail, a Great Ride that follows the old railway. Cyclists ride the flat river-level trail between Paeroa, Karangahake and Waihi, going right through the long lit tunnel (a torch or bike light makes this much more comfortable). It's an easy, mostly flat ride that families and casual riders manage happily, and you can link it with a stop at the Victoria Battery site or a coffee near the gorge. As with the walks, check whether the rail-trail section through the gorge is open before you set off, as storm damage has closed it at times. If you don't have bikes, hire is available along the trail.
The Victoria Battery at Waikino
A little way along at Waikino sit the remains of the Victoria Battery, built from 1897 to crush ore carted down from the Martha Mine at Waihi. In its day it was one of the largest ore-processing plants in the world, working around 800 tonnes a day using the then-new cyanide process, and it ran until 1952. The site is free to wander, with towering concrete kilns and foundations, and it's an easy add-on if you're curious how the gold was actually got out of the rock.
Getting there and parking
Karangahake Gorge is on SH2, roughly 10 minutes east of Paeroa and 10 minutes west of Waihi. It's an easy stop on the drive up to the Coromandel or across to the Bay of Plenty. The main Karangahake Reserve car park is signposted off the highway and is where most walks start, with toilets and information boards. There's a second car park at Waikino near the Victoria Battery, and a small one by Owharoa Falls. Car parks fill up on fine weekends and in summer, so arriving earlier in the day helps.
What to bring
Pack a torch or headlamp for every person, plenty of water, closed shoes with decent grip, and a warm layer, as the tunnels and gorge floor stay cool even on hot days. Bring a picnic if you fancy it, plus sun protection and insect repellent in summer. There's no shop on the tracks themselves, though there are cafes near the highway.
Best time to visit
Karangahake is good year-round. Summer is warmest and best for swimming, but it's also the busiest, so go early. Autumn and spring are quieter and pleasant for walking. Winter is fine too, just expect cooler tunnels and check track status, as the wet season brings the slip and flood closures. Avoid the gorge straight after heavy rain, when the river runs high and some tracks shut.
If you enjoy this, two other classic Coromandel outings are worth a look: the coastal walk to Cathedral Cove, and the bigger tramp up to the Pinnacles in the Kauaeranga Valley.

Frequently asked questions
Do you need a torch at Karangahake Gorge?
Yes. Bring a torch or headlamp for every person in your group. The Windows Walk goes through old mine tunnels that are genuinely dark between the window openings, and while the long railway tunnel is lit, the light is dim in the middle. A headlamp is best because it keeps your hands free on the uneven ground, but a phone torch will get you through in a pinch.
How long are the walks and are they easy?
Most of the walking is flat, well-formed and rated easy, following the old railway and river. The Windows Walk takes about an hour return, and the short rail-tunnel loop takes under an hour. You can combine them into a two-to-three-hour outing. Wear closed shoes with grip, as the mine-tunnel floors are rough and sometimes damp, and supervise children near the window openings, bridges and river.
Is Karangahake Gorge free to visit?
Yes. The gorge is mostly Department of Conservation and council land, and the walks, tunnels, Owharoa Falls and the Victoria Battery site are all free to access. There are free car parks at Karangahake Reserve, at Waikino and near Owharoa Falls. Just check DOC or Hauraki District Council for current track status before you go, as slips and storm damage sometimes close sections.
Can you cycle through Karangahake Gorge?
Yes. The gorge is one of the most popular sections of the Hauraki Rail Trail, a flat, mostly easy cycle route that runs between Paeroa and Waihi and goes right through the long lit railway tunnel. A torch or bike light makes the tunnel more comfortable. Bike hire is available along the trail. Check that the rail-trail section through the gorge is open before you set off, as storm damage has closed it at times.
