Big, rugged high country straddling the Seaward Kaikoura Range, well inland from the coast. The Clarence Valley opens up into a properly remote stretch of country, with wide views, plenty of river and stream crossings, and that backcountry feel you come out here for.

The section between the Kahutara gate and Quail Flat runs about 30 km and takes at least two hours. The road is steep, rough and narrow in places, with several fords along the way. Slips and floods happen, so safe passage can never be guaranteed. It's a hard route, but drivers reckon it's hugely rewarding, and a lot of them call this their favourite side of the valley.

Keep to the formed track, leave gates as you find them, and don't disrupt farm operations or stock. Access needs to be arranged through Colin Nimmo of Muzzle Station on +64 3 319 5791 or [email protected], and there's a road maintenance fee for motorised vehicles.

The road is closed over winter, from 1 May to 25 October.
