Rangituhi/Colonial Knob encompasses 110 hectares of scenic reserve, just a few minutes from Porirua city centre. There are three possible routes offering loop walks, so depending on your time, you can spend three to five hours there.
The more scenic route, beginning at the Broken Hill Road Carpark, takes you past the man-made lakes which once supplied water to Porirua Hospital and through Kohekohe Forest.
The high point, Mount Rangituhi, rises 468m west of Porirua City. On a clear day, you have views of the Inland Kaikoura Range in the South Island to Mount Taranaki in the northwest. Just below is Porirua Harbour (a unique drowned river valley) stretching out towards Paremata and the Pāuatahanui Inlet.
The trail starts from Camp Elsdon carpark and can be completed in both directions.
The summit can be accessed from Te Ara Utiwai trail or from Farm Road.
There are regular bus and train services to Porirua and the surrounding area. Timetables are available from the Metlink website.
