Location: George Denton Park and Polhill Reserve are located in the hills in north-west Brooklyn, and are both part of Waimapihi Reserve.
Entrance and exit points: Numerous, including Highbury Road, Holloway Road, Aro Street, Karepa Street, Ashton Fitchett Drive.
Brief description: This area contains a number of tracks for mountain bikes and walkers.
The Polhill Reserve Loop (built by volunteers) starts at the grassed area near the top of Aro Street and heads uphill on the Transient Track through regenerating native bush to Karepa Street. The Transient track leads to the start of the Highbury Fling track, which winds around the top of the valley to George Denton Park.
George Denton Park, at the end of Highbury Road, has a large grassed area and a playground. Squatters Track leads from the park down to Holloway Road.
At the end of Holloway Road, a stream flows through a pleasant picnic area before entering a culvert. The loop track beside the stream takes you a short way up the valley. Across a footbridge and behind the rustic gardeners’ work shed are two tracks: one leads steeply uphill to the Transient track and Ashton Fitchett Drive; the other follows the side of the ridge to the Aro Street entrance, crossing some private land.
The wind turbine and Te Kopahou Reserve can be reached from Ashton Fitchett Drive, and the Zealandia/Karori Sanctuary fenceline track can be followed all the way to Wrights Hill.
Parking: Parking is limited at all entrances.
Accessibility: Steep in parts.
Dogs: Dogs must be kept on a leash.
Mountain biking: Permitted on new tracks between the wind turbine and Aro Street.
