Kapakapanui is an isolated minor peak of 1102 metres in the southwest corner of the range, dominating the skyline from Paraparaumu and Waikanae.
The open summit of Kapakapanui is one of the best viewpoints in the Tararua Range, revealing not only the full extent of the Southern Crossing, but also the featureless forested maze of the Renata-Maymorn-Akatarawa uplands, as well as the sweep of the Kapiti coastline and the dramatic silhouette of Kapiti Island 22 km to the west.
The climb is steep and the track rough and muddy in places, with the forest still bearing the marks of the devastating 1936 cyclonic storm.
