Rangituhi / Colonial Knob rises 468 metres above Porirua and hosts a growing network of mountain bike trails on its eastern slopes. The trails, developed and maintained by the volunteer Mana Cycle Group, wind through regenerating native forest and open farmland within the Porirua Scenic Reserve and Colonial Knob Scenic Reserve. Riders enjoy a mix of easy two-way tracks, intermediate climbs and technical descents, with panoramic views over Porirua Harbour, Wellington and Cook Strait on clear days. The network provides convenient access for Porirua residents and visitors from central Wellington, roughly 25 to 30 minutes by car.

About the Trails
The Mana Cycle Group has developed a compact yet well-connected trail system on the eastern slopes of Rangituhi. Trails pass through kohekohe and regenerating native bush on the lower slopes before opening into farmland higher up. The network forms part of Ngā Ara o Rangituhi and caters to a wide range of abilities while also accommodating walkers and runners on shared sections.
Two primary access points serve the area. The Spicer Botanical Park car park on Broken Hill Road provides entry to the lower trails, while the Raiha Street summit road offers 4WD access closer to the upper network and lookout. Most riders begin at Spicer Botanical Park and climb through the forest before reaching the more open upper trails.
The summit lookout delivers sweeping views across Porirua Harbour, the Hutt Valley, Wellington and, on clear days, toward the South Island. The area remains popular for both local training rides and longer loops that combine multiple trails.
Key Trails
Te Ara Utiwai is the flagship climbing trail, a 6.1 km shared easy-to-intermediate route from the Camp Elsdon area to the Rangituhi Lookout. It winds through native bush with a gentle gradient that suits both climbing and descending in the approved direction.
The Doctor offers an easy 1.6 km two-way option through regenerating forest in the Colonial Knob Scenic Reserve, providing a gentle introduction suitable for beginners. Chimney Sweep is a short 0.6 km intermediate trail across upper farmland that connects with other routes near the summit.
Additional trails such as Tumeke and Crash Palace provide intermediate and more challenging options for riders seeking variety and flow.
