The B6301 is a cross-country B-road in central Durham.
The road starts on the A68 in Tow Law and heads northeast along Smith Street, soon reaching open country. It then runs along the top of a ridge, past a wind farm, climbing steadily as it goes. A deep valley opens up to the left and at the end of the ridge the road descends into it. It crosses the stream, the Headleyhope Burn, just before the B6302 turns off to the right.
The road now climbs up the far side of the valley, more steeply than the descent. It crosses a ridge before descending into the next valley, that of the River Browney. A few hundred yards after crossing the river the road enters Lanchester, where it ends at a T-junction on the B6296.
