An 18 km ridge walk along Wellington's Outer Green Belt, running between Erlestoke Crescent in Churton Park and Makara Saddle in Karori, over Mount Kaukau, the Crow's Nest, Kilmister Tops and Johnston Hill. It takes up to seven hours, but can be done in stages, as there are many entry and exit points. On a clear day the views reach the Kaikōura ranges, the Marlborough Sounds, Wellington city and harbour, and the Tararua and Orongorongo ranges. The route is challenging in places and exposed to extreme weather, and reasonable fitness is needed for the full walk. Bring warm clothing, sturdy footwear, lunch and plenty of water, as there are no toilets or water on the track. Follow the purple markers, and keep dogs on leads outside dog exercise areas. The listed access point is on Sirsi Terrace in Broadmeadows.
