Follow the Waterworks Walk to just before the dam where the track branches off to the right and climbs steeply up a well constructed set of steps and stairs. It is a 335 metre climb from Brownlee Avenue to the summit with 1349 steps! The track meets the Hakarimata Walkway and the summit tower at 374 metres above sea level.
In spring you can smell the scented daphne, Alseuosmia hakarimata or topara growing beside the track. The tower provides good views out towards the coast and across the Waikato Basin and down to Ruapehu on a clear day.
The Hakarimata Summit Track is accessed via the Waterworks Walk. The Waterworks Walk starts on Brownlee Avenue, off Hakarimata Road, approx. 1 km north of Ngaruawahia.
