Porter Road is a trickier forest side route winding through the hills of the Bay of Plenty. The track threads through native and plantation bush, with the close-in canopy giving it a secluded, shaded feel.

Expect uneven, root-laced ground and steep pinches that test traction, so this one suits drivers with some experience and a properly equipped rig. The surface turns greasy after rain, so take care on the slippery sections, and be prepared for a recovery — a winch may be required depending on conditions on the day.

Travel with a mate and carry recovery gear rather than tackling it solo. It's a short but rewarding challenge for those wanting more bite than the main routes through this forest country.
