An easy day trip out from Christchurch, this gravel run takes you through high-country farmland with two working stations on the valley flats and a forested stretch at the northern end. You can tackle it from either the Oxford/gorge end or the Okuku/Whiterock end, crossing over Okuku Pass. Classic high-country views, grazing stock, and a hunting and fishing paradise along the way.

Mostly easy going, but bumpy and rough in places, especially at the south end, and a little steep and winding here and there, so take your time. There are a few fords and stream crossings, one wider and deeper than the rest, and all can rise a lot after rain, so always get out and check the river first. A ute or genuine 4WD is the go over a standard car.

Plenty of farm gates, particularly up north where the forest meets the farmland, so leave them as you find them. Pack a picnic and a camera; there's a popular swimming hole under the first bridge. Makes a good outing for visitors, and a different experience again as a night drive if you've got a decent set of spotlights.
