The track starts from the Te Waipapa/Diamond Harbour wharf. If driving from Christchurch there is good parking in the small village above. Alternatively take the ferry across the harbour from Lyttelton to the wharf. From the wharf follow the road up towards the Village. After a few minutes walking a track leads off to the right, soon dropping down to the beach.
From the end of the beach, a rough track heads directly uphill, following a creek bed through pine forest and regenerating bush. Ignore any side tracks and follow the main trail up the creek. After crossing Marine Drive at a bend, turn right for the start of the next section. The track enters scrubby farmland, soon passing a large historic eucalyptus tree, believed to have been planted by the early European settler Mark Stoddart in the 1860s.
Cross the unsealed Bayview Road and veer slightly left to pick up the track again. This is last place within Diamond Harbour you could start the track, cutting about 30 minutes off your walking time.
The track climbs into farmland and passes the remains of a pioneer’s cob cottage. Mature gum trees planted here form a large square, outlining an overgrown garden. The vegetation from here on up is a combination of tussocks and introduced grasses.
After around 1 hr and 30 mins, the track levels off briefly and soon meets a 4WD track. The track then continues upwards for another hour. Chunks of dark rock littering the landscape are pieces of the old lava flow you are walking on. Very near the summit, a junction indicates 10 minutes left to continue to the summit, or 15 minutes right to the shelter.
The Mount Herbert/Te Ahu Patiki summit at 920 m is the highest peak on Banks Peninsula. The summit is dominated by tussocks, with a few speargrass plants, scattered around a small antenna housing. From here you can look out over the Port Hills to the peaks of the Foothill Forests – Mount Thomas (1023 m) and Mount Grey (933 m) 66 km to the north. To the east is open ocean all the way to Chile and Patagonia.
Either return the same way you came, or continue left on to the Port Levy Saddle and from there to the Rod Donald Hut in 3 hr 20 min. Alternatively you can exit right via Orton Bradley Park, Kaituna Valley or Gebbies Pass, and stay at the Packhorse Hut along the way, which is three hours walk from Mount Herbert. The summit tracks are all part of the Te Ara Pātaka/Summit Walkway.
There are toilets and water in Diamond Harbour and at the Mount Herbert Shelter.
Packhorse Hut and Rod Donald Hut must be booked in advance.
Book online or contact the DOC office.
From Lyttelton, drive around the bays to Diamond Harbour or take a public bus to Lyttelton and a ferry across the harbour to the wharf.
The track is a full day trip and very exposed to the weather, so trampers must be prepared for cold, heat, fog and wind, and take plenty of water and some food with them.
There are limited sources of drinking water on this track. Do not use stock water supplies. Roof collected water is available from Mt Herbert Shelter which should be treated before drinking.
There are toilets in Diamond Harbour and at the Mount Herbert Shelter.

Before you go into the outdoors, tell someone your plans and leave a date and time to raise the alarm if you haven't returned.
