Rapaki Track is a walking and mountain biking track on the Port Hills above Christchurch. It has a Google rating of 4.6 from 18 reviews. Reviewers mention the views, the trails and the chance to make a loop, and one calls it a staple of Christchurch tracks, challenging in parts.
The council's track page says the track starts at the junction of Rapaki Road and Centaurus Road in Hillsborough and finishes at the Rapaki Track car park on Summit Road. The track climbs steadily to a flat middle section, then climbs again to the car park, with views over Lyttelton Harbour. A short walk to the summit of Mt Vernon is possible from there, and a loop back by Huntsbury Track is also an option. Dogs must be kept on a lead.
For a view over Lyttelton Harbour and a loop walk on the Port Hills, this track above Christchurch is a place to plan your route and allow time for the climb.
