"Unique spot to take a 1km walk through an old tunnel and 3 bridges a beautiful walk along the water on the other side. Recommend taking a thin jumper/jersey for the tunnel walk as the wind flowing through is cool."
Neil Charteris
"We did the tunnel loop, was really nice on a hot summers day as it's cool inside. We started at the car park and did the loop so it was the tunnel then a nice Bushwalk around the gorge/river. Easy walk for all ages 7+. 28th Dec"

In-depth insights and expert knowledge
The History of the Karangahake Rail Tunnel
The tunnel was part of the Paeroa to Waihi railway line, which cost a substantial 141,762 Pounds to build. For decades, it served its purpose, humming with the activity of trains carrying the lifeblood of the region. After the decline of extensive gold mining operations and the phasing out of the railway, the tracks were eventually removed.
Today, the tunnel has been transformed into a walking and cycling path, forming a key part of the Karangahake Gorge Historic Walkway and the Hauraki Rail Trail. This repurposing allows visitors to experience a tangible link to the past, walking or biking through the very passage that once facilitated the region's economic boom. The surrounding gorge also features remnants of mining infrastructure, offering a comprehensive glimpse into this industrious era.
Experiencing the Tunnel Walk
The 1km journey through the tunnel is surprisingly atmospheric. You can almost feel the echoes of the past, imagining the trains that once rumbled through. The path is asphalted and wide enough to comfortably accommodate both walkers and cyclists.
Many visitors, including families, find the tunnel walk to be an easy and engaging activity. It’s a great way to break up a longer hike or cycle, or to simply enjoy a unique natural and historical attraction. The combination of the cool, dark tunnel and the bright, scenic gorge creates a memorable contrast.
