Kaiaraara Track to Mt Hobson (Hirakimata)

Kaiaraara Track offers a striking experience for walkers - a wide array of flora from tiny plants and ground cover to large trees in established forest, historic sites and, towards the summit, panoramas of the island, its bays and beaches and neighbouring islands.

From Forest Road, the track rises steadily to Cooper’s Castle Track junction, crossing the stream in several places using a series of suspension and wooden bridges. A short distance from this junction is a side-track to the remains of the Lower Kauri Dam. 

What remains of the Lower Kauri Dam (1 hr 30 min from Kaiaraara Hut) was built in the 1920s, along with six smaller dams higher up. Logs estimated to contain seven million feet of timber were slid into the dams. Once loaded, the dams were tripped one after the other so a full blast hit the lower dam, propelling the logs into Kaiaraara Bay. The Lower Dam was washed away in a storm in 2014 and only the base can be seen in the stream.

The track above the dam area winds through semi-mature forest with good examples of tōwai and large kohekohe. From here, the track climbs steeply via wooden steps that protect black petrel nesting grounds and sensitive ecosystems to the summit.

From Port Fitzroy, follow Kaiaraara Bay Road to its end. A short walk leads to Kaiaraara Hut and the start of the track.

Keep to the tracks to avoid damaging rare native plants and disturbing black petrels.
