Johnsonville Park is a bush reserve on the northern flanks of Mount Kaukau, above Johnsonville and the Ohariu Valley, in Wellington's Outer Green Belt. The reserve is part of one of the largest areas of continuous native vegetation in the city. The Northern Walkway climbs steeply from Truscott Avenue to Mount Kaukau and on to the Botanic Garden. The Skyline Walkway follows the ridge from the saddle of Old Coach Road.
The Old Coach Road trail is a wide heritage track that climbs from the Ohariu Valley to the ridgetop, and mountain bikers use it. A tunnel cut into rock near the top of the Truscott Avenue track dates from around 1910, and the old reservoir dam and pump can be seen at the top. There is a large car park at the Truscott Avenue entrance, and dogs must be kept on a lead. Our pick in Johnsonville for a climb with a view over the city.
