This track is usually ridden as a descent, though some hardy souls do ride up it for training.
The steep descent is over grassed farm track, with a couple of gates across the track.
When descending look for the sign that indicates the bike track to the left, as the walking track ahead is unrideable.
The bottom section (after the turn off to the left) - has very steep clay sections that can be a bit slippery in the wet, along with a few wooden drains to dodge. There is a gate halfway down this track that is always closed, so watch your speed.
On the Summit Rd just up the road (West) from Rapaki Track. The Farm Track is on the elbow of the road.
