The B4318 is a rural B-road in southern Pembrokeshire.
It starts at a roundabout on the A477 Sageston bypass (although of course originally it continued into the village). It heads east, climbing slowly, past the Manor House Wildlife Park and the Great Wedlock Dinosaur Experience before descending again.
After going through Gumfreston the road reaches the edge of Tenby. Although the B4318 continues straight ahead down the narrow Heywood Lane, the road layout and indeed the signs indicate that the road bends to the right into Clickett Lane to meet the A4139 by Tenby Leisure Centre.
Staying on the actual B4318 though into Tenby we come to a T-junction on the A4218, where it turns right for a short multiplex. Pedestrians can then turn left under the railway viaduct along St John's Hill to end on the A478 Norton close to the sea front. As St John's Hill is one-way vehicles can only use the road in the other direction; inbound traffic has to use the parallel Greenhill Road which some maps mark as part of the A4139.
