This is a Network of tracks in the Hunua Ranges, The Hunua Ranges form a block of hilly country to the southeast of Auckland in New Zealand's North Island. They contain 178 km² of parkland, and rise to 688 metres at Kohukohunui.
There a number of MTB options you can take, from down hill to XC loops. The tracks wind through native bush and are quite narrow with a hard gravel base in most tracks, there is the odd rooty section and some small river crossings. The XC tracks and flat in profile with some small grass hills that are used to connect them all together. These are a good option for a day out as it takes a bit to get there but worth the drive.
