The Historic Tunnel Hill Walk in the Catlins
The Tunnel Hill Walk, also known as the Historic Railway Tunnel Walk, is located 5.1 km north of Owaka along the Southern Scenic Route in the Catlins. This walk offers a unique opportunity to explore a piece of New Zealand's railway history. You can enjoy a scenic stroll through vibrant forest regrowth leading to a 250-metre historic railway tunnel. The tunnel is easily navigable with the light from a phone, and informational panels at both ends provide insights into the railway's history.
A Glimpse into Railway History
The Catlins Railway Line was constructed between 1879 and 1915 to facilitate timber transport, replacing the hazardous coastal shipping trade. The tunnel, completed in 1896, was part of the line that reached Owaka by 1897. As timber resources dwindled and road infrastructure improved, the railway was gradually phased out, closing entirely in 1971.
Exploring Railway Remnants
Several remnants of the railway era remain in the area. The Owaka Museum offers an excellent overview of the railway's history. Visitors can also walk a section of the track from the Matai Falls Track, which takes about an hour and includes a cutting with informative panels.
The railway once featured 16 stations, some of which supported forestry tramways. Exploring side roads reveals railway-style place name signs, including those for Owaka, Tawanui, Houipapa, and Caberfeidh. In Mclennan, a surviving station is visible on private land along the highway.
The Sir Truby King Bridge
In Tahakopa, you can find the remnants of a railway bridge designed by Sir Truby King, a notable Catlins resident. This bridge, the only one privately built to New Zealand railway standards, is now part of the Sir Truby King Bridge Walk. Although not widely known, it is a significant part of the Catlins' heritage.
How to Get There
To reach the Tunnel Hill Walk, travel south along the Southern Scenic Route from Balclutha on the Owaka Highway to a point 5.1 km north of Owaka. The track begins at the roadside, leading downhill along a fence line to the historic railway line.
Other nearby attractions include Kaka Point, Nugget Point, Cannibal Bay, Pounawea and Surat Bay.
