Otira: Tunnel History and Walking Tracks

Otira combines a distinctive transport history with alpine tracks in the surrounding area. The settlement grew during construction of the Ōtira railway tunnel from 1907 to 1923 and remained a railway maintenance base until 1999. This history runs through different perspectives on the area: the road and railway cross or pass through the mountain pass, while walking tracks lead into nearby valleys and to a lake.

Gorge, Mountain Pass Road and Railway Tunnel

The road through the Ōtira Gorge and over Arthur’s Pass connects the townships of Arthur’s Pass and Ōtira over a distance of 13.4 kilometres. There are several viewpoints and signposted lookout points along the road. The railway line is also part of the area’s transport history: the TranzAlpine train between Christchurch and Greymouth, in both directions, travels through the Ōtira Tunnel. The road and railway thus offer different ways to experience this crossing of the pass.

On the so-called town side of Ōtira, the old post office was converted into the John Burns Gallery of Modern Art. Alongside the railway history, the conversion of a former post office into a gallery is now part of the townscape. This adds a cultural dimension to the picture of Otira without taking the tunnel’s history out of focus.

Walking Tracks Near Otira

Harper Pass combines a specific walking destination with a longer history: for Māori who traded in pounamu (greenstone), it was the main route to and from the West Coast. The Harper Pass Route starts at the Aickens car park beside SH73, five kilometres west of Ōtira. To access the Taramakau Valley, you must cross the Ōtira River. As access and conditions at river crossings can change, check them before setting out.

Another route through the area leads through Deception Valley to Goat Pass. A footbridge a few kilometres from Aickens Corner provides access across the Ōtira River to Deception Valley. The two destinations can therefore be distinguished by their different landmarks: the Harper Pass route involves a river crossing to access the Taramakau Valley, while the route through Deception Valley leads to Goat Pass.

The Lake Kaurapataka Route offers a different sequence of landscapes. It passes through red beech forest to the confluence of Pfeifer Creek and the stream flowing out of the lake, crosses the stream, then continues along the left bank to the lake. There are several suitable camping spots on the lakeshore; cairns mark the turn-offs to these sites. The route is suitable for well-equipped people with backcountry hiking experience. River crossings and route-finding are part of the trip, as is checking current river and weather conditions.

The Otira Valley Track runs through a deeply incised alpine valley on the northern slope of Mount Rolleston/Kaimatau to a footbridge over the Ōtira River. In fine weather, you may see summer alpine flowers there. The described highlights differ from those of the Lake Kaurapataka Route: here, the alpine valley and the possibility of seeing flowers shape the walk, while there, the key features are red beech forest, a stream crossing and the lakeshore.

Choosing the Right Base for Your Trip

When looking for a holiday rental in Otira, the activities you want to enjoy each day can be a useful guide. The area’s history and tunnel, as well as the viewpoints along the road, are complemented by walks with different landscapes and levels of difficulty. If you are considering the Lake Kaurapataka Route, take into account the stated requirements for experience, equipment and route-finding. For the Harper Pass route, the river crossing to the Taramakau Valley is a specific planning consideration. This lets you choose which parts of the area to explore based on the routes that suit your trip, rather than treating every outing as a similar stroll.
