Millerton is a tiny settlement 2 minutes inland from Granity on the upper West Coast. Millerton Road is no longer maintained and the center portion of the road is now blocked off and heavily overgrown in places and referred to as Millerton Track.
At the North (Bottom) end of The Millerton Trail the track is blocked by a barrier and stones across the entrance to a bridge.
The South (Top) end starts with a big earth bank. I scouted around it, and there was a curved flat section around the mound, not much more than a tyre wide but enough to get the GSA through.
Millerton Track is barely a lane wide when clear, and less so when ducking under trees.
