Walking
Enjoy the views from the summit of Mt William, just south of the Bombay Hills.
McMillan Rd car park to Mt William summit
Time: 1 hour 30 minutes one way
Distance: 2.5 km one way
From the McMillan Rd end, the track follows a farm fence line with markers to the Mt William Scenic Reserve. The reserve hosts a wide variety of native trees and shrubs, including kauri, hard beech and king ferns. From the Mt William summit (373 m) there are expansive views to the West Coast and Firth of Thames. Note that a fence has been erected restricting access to the trig. Visitors are welcome to cross the fence at a corner post. A stile will be added in the near future to improve access to the trig.
Mt William summit onto Puketutu trig and Puketutu Rd
Time: 1 hour 30 minutes one way
Distance: 2 km one way
The track continues along a saddle of rolling farmland to Puketutu trig (376 m) and Puketutu Rd.
Conditions
No dogs. The farmland section of the track from Puketutu Road to the reserve boundary (so no access to the trig) is closed for lambing from 1 August to 1 October. The reserve section from McMillan Road to the farmland remains open.
How to get here
