What a stunning 8.3km track! The Cossey-Massey Loop Track commences at the spectacular Hunua Falls, climbs and descends through mature native bush filled with bird-song and sidles next to Cossey Dam, one of Auckland’s precious water supply lakes.
The track is very well maintained and combines the feeling of a serious tramp with a local walking track – a great intermediate hike. The highest altitude of 353m ensures you get a great workout as you enjoy the beautiful surroundings. It is important to realise that there are plenty of stairs nearer the ends of both the tracks as well as one river crossing on the Cossey Track.

Cossey – Massey Loop Walk Description
This walk combines two Hunua Tracks, the Cosseys Gorge Track and Massey Track into a fantastic 8.3km loop. The loop can be walked in either direction, both have a significant number of stairs to climb in the first part of the walk and therefore to descend as you get nearer the completion of the loop.
The walk commences from the main carpark at Hunua Falls, and after completing the Kauri dieback cleaning station, enjoy the views of the cascading falls from the bridge as you cross the river to start your walk. Turn left to complete the Cossey-Massey Track rather than the Falls Loop Track. Walk approximately 300m uphill until you reach the junction of the two tracks, take the Cossey Track to walk clockwise or commence the stairs on the Massey Track to walk anti-clockwise.
The clockwise route has an early river crossing and very steep stairs to ascend, while the anti-clockwise route has more flights of stairs but is not as steep.

The track is in great shape, with a generally wide gravel path that winds its way through the thick and lush native bush. There are great views of the dam at various lookouts along the track and you get to walk across the front wall of the dam, a nice place to stop for a picnic, with toilets nearby.
Buggies and Wheelchairs
This track is not suitable for buggies or wheelchairs as it has many stairs!
