The first kilometre from Otanerito beach is through farmland alongside the creek, but for most of the way upvalley the route traverses Hinewai Reserve through extensive regenerating native forest and some mature old-growth beech forest. The gradient is gentle at first, following the lower reaches of Narbey Stream, with short sidetracks leading to waterfalls. The second half of the ascent is steeper but under shady forest canopies. Eventually you emerge into a parkland of native trees and pasture at Brocheries Flat, before making the last short climb to Purple Peak saddle, 590m above sea level. Akaroa Harbour spreads out below you like a satellite image. For the energetic, a 40 minute steep side track leads to the even loftier viewpoint of Taraterehu, or Stony Bay Peak, 806m. From the saddle the track descends quite steeply through grassy farmland gullied with native bush and surrounded by spacious views in all directions, finally entering town by Mt Vernon Lodge and Rue Balguerie.
